Again issues with the wife's 2002 Volvo S60 (non-turbo).
|UPDATED|10/20/2014 5:45:20 PM (AZT)|/UPDATED|
She reporting that the fan blower works only intermittently. I could not get it to work at all tonight. The fan speed is controlled by an analog knob. Also, the A/C switch (which has it's own electronic push-button on/off switch) seems to be turning itself on and off at random times.
I already checked the fan motor fuse which is fine. (Of course, it should be if it works occasionally.)
I'm thinking it could be loose connection to the fan motor, a bad fan motor, or a bad Climate Control Module, which, from what I can tell, means replacing the entire dashboard control panel.
Any thoughts on this stuff?
Thanks!

Adam, take it in to a shop that can scan it for HVAC codes.....see what pops up, and go from there.
Yer prolly on the right track thinking it's the module, but it could certainly be a loose/corroded connection somewhere.

Yes..it could
No
Afaik...no.
Autozone et al can only scan for OBDII codes(emissions related). Plus, being a Sveedish car, the HVAC system may require a specific protocol for diagnostics. I can look once I get to the shop, and see what might be up with it.
Replacing the dash module with a newer, or different type module will most likely not work. The CAN(communication area network)communication between the four thousand(slight exaggeration) different modules on the car has to be right....changing to a different type module prolly will disrupt that. HVAC is not my field, so anything is possible.
You might only need the fan switch, might be a relay going goofy, or any one of many other possibilities.

Adam, the HVAC codes can only be accessed by a capable scanner. The module is the control panel itself....easy enough to swap, I s'pose. Since you say the A/C seems to also have a mind of it's own, I'd be suspecting a problem with the CCM, as you are. The CCM will need programing to get all the doors, fan, and temps to work properly, according to Alldata.....
There is also a fan control module....a little harder to get to.
I'd still suggest taking it to a shop that has a capable scanner to get codes before spending $$$$ on a module that may or may not fix it. Most of the latest scanners(good ones) from Crap-On or Matco will do it....ours will, anyway.

Thanks for the info. Took it to my mechanic to pull codes. It said "low blower motor".
So, I'm going to pick up a fan motor from my Volvo dealer and try to replace it myself. Any way to look up with the book-time is for this job? Do you happen to have access to a professional how-to for it? (Instead of an armature video, that is.)
Thanks!

I emailed you a link to the r&r procedure. Not sure if you can open it, so let me know. If you cannot get access, I'll copy it and send it that way.
Shows .9 hours to replace.
