i recently installed an aftermarket stereo in my ls. after the installation my ac unit is not working. all the fuses relays and wires r fine. clock and seat belt warning is also working only ac doesn't work. any help!!!

 

What year....?
How do you mean it does not work? Doesn't get cold? Doesn't blow through certain zones? Climate control unit doesn't turn on?



Who did the install? Where did you/they tap into for power and remote? How did you/they run the wires from the battery and through the car? Any other work done?

 

A/C system has a diagnosis system. On 95-97 you turn the ignition system on while pressing Auto and Recirculate.
