I just installed a '97 into my '95 2 days ago because it had fried. Three green plugs in the back as well and so far so good. No issues except for my trip computer which doesn't want to work. Not sure if there is any relation there.

OK, update! I installed the used control module and my A/C is back on again. No flashing as of yet. I haven't checked for codes though. I have noticed that my trip computer no longer functions. Is this directly tied to anything that we've been working on? I will be keeping a close eye on the A/C ...

hmmm.......do you guys think this could be a fan resistor problem. Isn't running only on High the symptom of a failed resistor pack? Brandonium, you might try searching on that to see if it gives you any useful information.....still looking for simple, less costly explanations. :)

Do you think a ...

EBAY!!!

There are more I'm sure, if you refine your search a little more. Does that look like the one in your car ...

Is this part not available except from the dealer? I cannot find a Auto Climate module from any of the online sources.

So this morning I re-installed the A/C control unit, cleaned out the sensors near the grab handles and checked DTC's. Still no go.

The blower comes on high but that's all I get. No power or control from the unit itself. Is there a built in mechanism that tells the blower motor to run on high in ...

I seem to recall similar symptoms once, including the fan behavior, when my cabin temperature sensor was clogged with dust but it never went as far as total system failure. I think in you model there is one located in each grab bar above the front doors. Just blow them out with a brief squirt from ...

OK, I removed the A/C control unit and removed the top & fascia. I can see no issue, burns and it doesn't smell as though it has cooked. I checked the DTC's and was unable to pull any codes from B1. Only B2 contained codes. Fuses check out fine. I am not sure where to go next.

Hello All,

For the past 2 years my A/C Auto Climate Control would flash upon start-up (A/C + Recir). A few weeks ago it started flashing while driving followed by the lights turning off and the fan going into High speed. The climate control unit would then come back on and I would have control ...

Well, I think I am relenting and may probably finish all but the CV axles then drive it a mile down the road for a shop to finish. I jumped on it for an hour yesterday and while my new bar and socket didn't break it sure didn't budge. The Volvo is parked right next to my collector vehicle so I am ...
