    Climate Control Replacement

    I recently purchased a 2008 Escalade that had button wear on the climate control unit. I ordered a new unit and replaced, easy fix besides the cost. My question is, does this have to be dealer programmed or is this just a user changeable item?

    Since I've changed it, once it reaches the desired temp (using auto) the vents stop producing air and the blower motor will be louder than usual. If I manually cycle the fan control up to high the blower will be extremely loud and then after a few seconds quite down and blow as normal. The rear does not stop and opertaes as normal during this time.

    Is this a coinsidence that my blower motor or blower module is going out at the time same time I replaced the head unit or does it need programming? Thanks for any help.

    Hello computerman,

    I would be more than happy to reach out to the dealership in regards to if this unit needs programming in regards to this concern. I see that you are looking for the other community member’s input but I just wanted to extend my assistance if you would like it. Thank you very much for taking the time to read my post. If you would like my assistance, please just send me a private message with your name, contact info, VIN, mileage, and dealership you would like me to contact.

    Make sure it is the exact part number on the back of unit, they are different models even though looking the same, no reprogramming must be same model number

    So I found out from searching other forums that new 2007 and up climate controls must be programmed to your specific vehicle to work correctly. I was apprehensive to spend the $70+ to get this done and possibly not fix the problem. I gave in and did it...after 30 minutes at the dealership it now works great. As an alternative, the tech suggested I could have just removed the faceplate from the new one and installed on the old unit which would have saved me the programming cost. Only 4 hex screws hold the faceplate on. Hopefully this will help someone else.

    it would be better if they just sold the button instead of buying the whole damm module

    I had the exact same issue on my '09. Glad you found the issue. There is actually a TSB that exists about it. If you replace the climate control head unit and don't get it programmed to mate to the vehicle, your condenser will freeze up on you. That's why the air stops blowing and the fan sounds like a jet taking off, it's blowing against a block of ice. Easy way to visually see the issue is to pop the hood when it happens and your AC lines will be coated in thick frost.
