Hi there,
I had this car for about an year and got 110K miles on it. All of a sudden, my AC stopped working. I took to a local mechanic and he changed the Body Control Module, followed by the AC Controller. He tried everything he knew, and kept the car in his garage for 5 days! Finally he gave up and gave the car back after he put all the old parts back.

Now the AC & Stereo do not work (Yes, Stereo worked just fine until this guy touched my car). On top of it, I see the 'Airbag Deployed' symbol turned ON! I have no clue what could have gone wrong, during the repair. Should I have to take it to dealer? Any guess?? Appreciate any help.

Cheers
Safuvan

I also lost one of the Power Windows (left-rear) which was working just fine, last week!

Sounds like the Multiplex Control Unit. It's inside the under-dash fuse/relay box.

My left-rear door is now "OUT OF" the Central Locking! This one doesn't lock/unlock when central locking is used! This was also working fine before the vehicle was repaired. Can this also be a Multiplex Control Unit thing?

Short answer-yes, it basically controls everything.

Get a service manual. It has like 20 pages of troubleshooting for the MCU.

I gave the car to another mechanic and their diagnosis was "Possible Computer" problem and recommended me to take the car to a dealer. I live in Tampa, FL. Can anyone suggest one reliable dealer around?
