Fixed it !!! your a genius
Same thing happened to me, battery went flat & jump started the car (2001 v70 T5) I lost all the climate control,fan, electric mirrors, heated seats, courtesy lights, remote locking, I got a replacement off eBay but the part number was slightly different, the heater worked but had all sorts of electrical gremlins, after reading the thread I thought it was worth a try....I took the themister off the eBay purchase & fitted to my old dead unit, it burst into life & everything worked perfect & all the gremlins disappeared (so far) so all in all very happy indeed, the local Volvo dealer said on that age of car it would be cheaper to scrap it that fit a new unit, it's unbelievable that that tiny bit can cause so many problems, thanks again

Please tell me how to do this!
Ok...I can now say that I am the CCM expert. After weeks of researching and trying different things, today, I achieved success. My CCM is alive, all functions are normal, and everything is working including the shift lever lights.
First, to recap what I tried (This is only for those that will find this thread when they find themselves in the same situation - and Im sure there will be many because this CCM is a piece of S#i+.)
I tried to unhook battery, touch two together to reset modules and that did not work.
I also left the battery unhooked for several days to make sure that I could reset modules- also did not work.
Someone had luck "jump starting" the battery to send a spike and that seems to wake up the CCM. I tried this a few times too - no go.
I also tried to take CCM out and thereby cutting off its source of power, and then reconnect to see if I could reset it that way - no go.
Most of you at this point would have said its your CCM - you have to replace with a new one 1200, or get a used one 40-50 dollars, and then pay Volvo to reload software (120-130). I said, NO WAY!.
I remembered a post by a guy that had managed to jump the CCM at the thermistor and had revived a dead CCM. I figured, why not? Well, it worked! It worked, and it is seems to be a permanent fix. I went ahead and ordered a CCM I found cheap on ebay (30 bucks) and figured I would just replace the thermistor since it seems this is the faulty part that shuts the CCM down.
Anyway, if you are reading this and have any questions, msg me and I can help you get your AC, head rests, STC, and Valet functions going again, for 0 dollars. I used a piece of wire that I had left over from my other shenanigans, so it did not cost me anything more than my time. Taking CCM off is easy, and this whole process could probably be done in less than an hour.
One word of caution: Disconnect battery when connecting or disconnecting the CCM. Otherwise it will turn on airbag light...I did follow my own advice, but because I was experimenting with different ways to wake the CCM before I jumped the thermistor, I knew it was going to set it off but figured I would rather have AC and a annoying light, than no light and no AC. You can avoid setting off light if you do it the right way.
Thanks for everyone's help. My hope is that others will have an easier time learning from my trials and tribulations.

Volvo XC-90 AC fan blower
I recently bought a used Volvo XC90 2004 and it had a host of issues. Most were outside and cosmetic, which were rectified easily.
One of the issues that was on the inside is the fan blower running even after the engine is turned off.
Here were a couple of things I tried:
1. Removing the fuse and replacing it- this did not work, but the fan kust kept running. When I took the fuse out however, it was hot, which is an indication that something was shorting out.
2. The fan speed was not responding to the CCM controls. That is the fan was on high all the time and I could not turn it off.
3. I tried adding a toggle switch to the fan blower, but apparently, the system is very sensitive so that did not work
4. I bought a used CCM from ebay and replaced that, but that did not work either. The problem persisted.
5. I read finally a forum about the fan blower resistor from a mechanic who posted online and in his explanation he said that the reason the fan blows at one constant speed is that the fan blower resistor is bad.
I tried that and after some long hours of removing the fan blower and replacing the resistor, the system was functioning like new again.
If anyone has any questions please do message me and perhaps I can give some help.
