trailblazer

I recently( this week) got a 2002 trailblazer. i have a problem with the airconditioner coming on when you turn the knob to 1 or 2. it only comes on when it is set to 3. any suggestions. i am calling the dealer cause its still under warrenty. haven't had it a week yet. should i anticipate any problems from this vehicle that any one is aware of. thanks

did you check the dash control switch for the airconditioning system?
also see if the relay is malfucntioning. my past a/c trouble was about
the condenser. during a frontal crash, it was wacked. the
a/c
condenser was the only new part i installed in my a/c system.

i took it back to the dealer and they replaced the sensor or relay whatever. now since they disconnected the battery the remote lock and unlock doesn't work. it worked when i took it up there. does it need to be reset after the battery has been disconnected. if so how do i do that.

I think you have to take it to the dealership to get your kep fob to work and re programed. there is nothing on it or in your car to make them work together that you can do yourself.
