Hi,
My 2001 S60 just developed a new problem. The interior climate motor started running continuously with ignition off. Wifes car, she parked it and of course came back to a dead battery. I pulled the fuse for a quick fix.

So my initial thought was that this was due to a bad Relay. I spent a couple hours researching this problem, and could not find any specific relay to control the climate Control system. So yesterday I took the time to pull all of them/with the exception of a few of the smaller relays in the trunk. Bottom line- No Love, the blower motor continued to run.

Researched every thread on the subject this morning and am leaning towards replacing the Resistor again, [ I did replace the heater resistor within the last year or two.]

A couple of threads stated the Climate control Module could be faulty.
Any Thoughts on how best to isolate and trouble shoot by problem are appreciated!?

Is there a dedicated relay for the Climate Control, if so where is it located?

Does my car have both a heater resistor and climate control Modual?

Also my issue of Vida has expired so I cant access any of the information

PS, I posted this yesterday under S60 but had no replies so I am reposting here!

 

Can anyone tell me if the Climate fan is switched through a Relay. IF so where is it located?
