Hello,

I have a 2000 Bravada and the climate control is not responding.

We just went through Hurricane Irma in Florida and after the hurricane left, we had to get more gas for the generator. On the way back to our house, the roads were flooded because the runoff had time to go downhill. After detouring multiple times, we eventually had to travel through one flood and the water was really high. There were smaller cars like mustangs going through and police present. Luckily no water came in to the cab but the wake of an oncoming car was worrisome. We made it back home to the dogs no problem.

Today we got back in the car and noticed that the air was not blowing. All the status lights for recirc/vent/ac/rear def. were solid on and would not turn off. I disconnected the battery for a few minutes and reconnected it. Now the lights are all off but the ac compressor is running.

None of the dials nor buttons will respond to changes. All fuses are fine too.

Someone suggested on another, older thread to check the Motor Control Module but I do not think this would be the issue as it is not just the blower that has the issue.

Thank you in advance

 

Not 100% familiar with your electrical, but chances are the water got into some of your control boxes and or connectors. It may start working when it finally evaporates.
