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.

Would it have codes even if no indicators are showing on the dash? Is Autozone or Advanced capable of doing a proper code scan?

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".

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.
