Hi

My climate control panel on my 2002 V70 2.4 Turbo (65,000 miles) is stopped working after a battery replacement...

Background: my battery was getting weak and I went to O'Reilies (parts store) and they checked the battery (while it was installed in the car), and confirmed I needed a new battery. I bought a battery from them ($100) and they asked if they wanted me to put it in and I said sure.

Now that the battery is in, my climate control panel is not working at all (shifter light is also not working). Everything else works fine. I have checked fuses and couldn't find anything (maybe I missed something, but I don't think so).

I have seen a few other posts on this, but I only saw suggestions of disconnecting the battery, then connecting the positive and negative leads for 30 seconds, then reconnecting the battery, to "reboot" the system. I have done this a couple of times with no luck.

The nearest dealership is 100 miles away. I have seen other posts that suggest the CCM can be "reprogrammed" at the dealer, or that the CCM may need replacing for about $1,000.

Did a simply battery replacement really cause a $1,000 problem? Does anyone have suggestions on things I can do to revive my climate control. Can a swap a used Climate Control panel into my car, or will it still have to be programed?

Any suggestions, help, or similar experiences would greatly be appreciated. My apologies if this is already addressed on the forum, but I did search and I haven't found a solution...

Please help... Thanks

Hello, Remove the battery and touch the cable clamps to clear the car's "short term memory". Turn the key to Pos. II, fan to zero (off). Now reconnect the battery. I read this on one of these boards a while back. MAYBE the "lock-and-unlock-the-car-5-times" trick was employed too. I read that it reestablishes communications among the seperate modules. Good Luck.

Thanks for your response. I tried removing the battery and touching the clamps, then reconnecting with key in position II yesterday (a couple of times in fact). Note that I don't think I can turn the fan to "zero" due to the way the controls work and the automatic climate control?

Regardless, still no luck. I didn't try the "lock-and-unlock-the-car-5-times" trick, but I will try that tonight.

I wonder if there is something I am missing, or an extra step to the procedure above?

Any other suggestions or experiences would certainly be appreciated.

Thanks

I tried disconnecting the battery, touching the clamps, then reconnecting with key in position II, then locked unlocked several times, but climate control panel still shows no signs of life...

Anyone have any other ideas?

Thanks

Well, I finally took it to the Volvo dealer in Chattanooga TN and they "reloaded" the software and it fixed it! They charged about $120 for the software reload.

I had called the Dealership in Nashville and they said the CCM would have to be replaced and it would cost about $1,000 and that the software could not be reloaded. I even emailed Volvo corporate asking if they had any info on how disconnecting the battery could cause this to fail, and they actually called me back the next day, but they basically said too bad. The guy that called even suggested that maybe it was just a coincidence that the CCM failed at the exact same time the battery was replaced. I told him that "he and I both knew that was not the case". He then suggested that the battery had been installed incorrectly causing the damage to the CCM, so I asked him how a battery could be installed incorrectly other than connecting the wrong terminals to the wrong cables. He said he was not a mechanic, so he couldn't answer that, but that the car was out of warranty so damage would not be covered. I then told him that I was simply trying to figure out what could have happened so that I could get it fixed, but he really didn't have any answers. I was VERY unimpressed and this was obviously just a lip service courtesy call and they had no intention of giving me any information on what could have caused this... Really lost faith in Volvo on this.

However, I was very happy with Volvo of Chattanooga and they were very helpful. They also fixed my fuel pump (they informed me it had been recalled). They also said my alternator was failing (I have had occasional "low voltage" warnings), so they also replaced it (this was NOT cheap, but I figure it had to be done). Overall I was happy with Chattanooga Volvo!

Bottom line, the Vovlo technician said that software can typically be "reloaded" to the CCM to fix this.

I have the same car, but can't remember when there was a recall on the fuel pump?

 

It came out about 1 to 1.5 years ago. It is mainly for cars in warmer climates. The plastic nipple or regulator cracks on the assembly causing a fuel leak. The warranty/recall I believe is good for 10 years 150K miles.

 

I don't normally post, but given that i actually troubleshot my issue with success and with the method so many of these CCM threads suggest hasn't work for anyone... i figured i would share.

I have a 2001 v70 T5M, woke up on this 15F morning to the lower panel on my console not working (you know, the one that has the seater warmers, fan control, heat control, defroster... ya...). None of the lights on this panel were on.., none of the electronic controls worked.

First i checked fuses 23, 24, & 25 via the driver's side door fuse panel (its the one neatly tucked into the end/side of the dash that meets the door jam). (don't forget to use the nifty fuse puller that is on the plastic panel that houses the extra fuses). None were bad. I thought for a fleeting moment one had been loose, but apparently not.

Anyhow, i took the advice so frequently stated "to have never worked for anyone" that is, i touched the positive and negative leads of the battery harness together for about 30 seconds and after-wards all has returned to normal...

The scary part is the thought of what the dealer might have charged me either for the part i didn't need or for their monkeys banging on things to determine the same thing i did in about 5-6 minutes.

Hopes this helps at least one person.

P.S. Change your upper engine mount, strut brace mounts, and lower torque rod yourself.. its cheap.. and it makes a huge difference on an aging car...

 

Just for clarification, I hope you disconnected the battery terminals from the battery first before you did this; yes???

 

I have 2005 V70 and on the positive cable there is another cable connected to the battery - I think the second cable is the ground cable. when you touch the the positive and negative cables do you do it with or without the ground cable.

Please read my problem on another thread:

Climate control LED lights always on

 

Hello, Holy Cow! It's almost one year after Leej got his ACC system back. Could you please post the part number of the download you purchased in Chattanooga? A part number always helps to move the conversation along-especially when $1,000 part replacements are being tossed around. I swear those dealership people have left the world of reality. When I got my transmission downloaded the gal in the service department blithely said, "Oh, the double bump (upon engagement) means you need a new transmission". She said it like it was a run in my stockings. Kira

 

I was having the same problem with a dead climate control module after disconnecting the battery on my 2002 v70. i tried disconnecting the battery again, shorting the leads, and reconnecting with the key at position 2, to no avail. I managed to get my climate control back again when I jump started the car after the battery conveniently crapped out. then i got a new battery and when i installed it the ccm died. i jumped it again, with the new battery still hooked up, and the ccm came back. it's something try.

 

Had to have ball joints and a few other things replaced after one failed-horrible experience but luckily happened in driveway of my work! Had repaired and when I went to pick up my car was asked if I had always had a 'dead' dashboard and a 'rough' engine. The odometer light bulb is out-but you can still read it-other than that NO!

Went out to car, turned it on, and first thought was what happened to my full gas tank! Then realized none of the gauges were operating! Mechanic did some research and reset something and got the dash back and the engine running smoother. All happy until I go to crank on the AC -nothing. Same as other posts I see here-climate control, bottom of the panel with the head rest release etc. and the shift lights not working.

Owner of shop spent almost 2 hours trying all the 'tricks' he could find on internet-seem to be same as most I have found. Could jump starting it be the trick? And as I know next to nothing about cars-do I have to let the battery die first? Worried the dash will go out again! What's the trick to that?

Would also like the part number/name of the software to reboot if necessary. Thanks for help and sorry for lengthy post!

 

 

I have a problem with the auto lights not turning on when i open any doors, but when i tap on the light cover (basically turning on the switch the light turns on). But i have more problems than that..........my cluster gauges and lights don't work (but it can do the self or trip test), the headlights, hazard, signal, and highbeam don't work (but the left parking light turns on when i start the car even when i don't turn it on), the AC/Heater control and lights don't work (but the fan blower will turn on even though i don't turn on the fan), and the power locks don't work. All this happened at the same time in my 2001 Chrysler Town and Country. It happened after the battery died and i have a towing company charge the battery and that's when everything starts malfunctioning. The tech checked the battery and alternator voltage and fuses and they are all good. I checked grounding and loose connection under the dashboard and they are all intact. The only thing i noticed and maybe can be a culprit is a short, ignition switch (i don't know if this has something to do with auto interior dome lights when car door is open), or a reset in the BCM or some computer module that controls all these thing (which i don't know how to do). Also, the battery is less than a year old and Alternator voltage is good. Please help me! thanks.

 

Here's something to try, I didn't think it would help, but it did in my situation. (CCM Lights always on, cluster going out, random things not working)

First disconnect battery. Unplug all the radio connections. (CCM needs to come out first, but reconnect after unplugging radio) Then reconnect battery with key in POSII check if symptoms still present.

Next try the same above, except with the plug behind the mirror.


After driving the car for 2 days with these two things unplugged, I plugged them back in and all was back to normal and everything works as it should without issue for over 10 months.

 

Hi
I have a v70 td 1998 without trip comp. Also I have the computer(engine) and clock instruments from a same type of v70 td. Could you please help me what should I do?

Tx a lot,

jepe

 

when you say jump start it do you mean hooking up cables to another car and jump it?
