Climate Control Module Troubleshooting

broadusc · Post by **broadusc** » 13 Nov 2017, 23:06

I've looked at the other threads here, but don't see a solution. My climate control module has gotten more dodgy as time has gone on since I bought the car a few months back and now can go a day without working at all, which isn't great in the winter. When I first bought the car, I replaced the blower motor transistor, and things worked through the summer. Now the AC and Recirculate buttons flash when I start the car and the blower motor is very inconsistent whether it works or not. I bought a used climate control module on eBay, and I'm getting the same exact results now that I've installed it. What else can I do to troubleshoot this? Although not impossible, I'm assuming that two climate control modules are unlikely to have the same problem and it must be something else.

Tough to find good testing information on these. I've tried as well, but it sounds like yours is even worse than mine.

Xemodex has repair services listed on their website. About $350.

The blinking lights indicate a problem has been detected. You need a scan tool to get the codes and determine a solution. The blower should always work in 'manual' mode, but check it to determine if it runs slow or fast only. The blinking lights can also be caused by a dirty cabin temp sensor.

The "manual" mode is either on or off. If the unit is working, I can set it to any fan speed. If it's not, it's just dead. The fan control does nothing. I've hooked up my code scanner, but it's not throwing any code. I've cleaned the cabin temp sensor on both and both had a little dust bunny on them. Since my original post, I have to say that the "new" used climate control module is more consistent than the original one that came with the car. It usually works after it's been sitting overnight (thankfully), but if you shut it off to run in the store, it won't work when you come back out and start it up again, and then may not work until the next time it sits for a while. If you put in on auto, it's pretty much the same behavior.

A generic scan tool will not work, you need VIDA/DICE or a Volvo scan tool that can check Volvo specific codes. One that also can be used for SRS, ABS, and CEM codes. Not cheap, unless it is PC based and you have a spare laptop.

Ultimately, this turned out to be a bad blower motor. It finally went 100% kaput, so I had a local shop scan it to be sure and it was throwing the bad blower motor code. I swapped it out and it works like a champ now.
