How to Troubleshoot the Air Conditioning in a Cadillac Escaladeby Contributor
Problems with an air conditioning system can be time consuming and costly to fix in a vehicle. Save some time and money by trying to troubleshoot the air conditioning problems on your own. Learn how to diagnose these problems in a Cadillac Escalade and possibly avoid a trip to the dealer.
Listen for the blower motor first. If working properly, the noise of the blower motor will increase when the air is turned to high and decrease when it is turned to low.
Find the blower motor in a Cadillac Escalade by removing the trim panel directly below the glove box. The blower motor is a black piece with a white colander-looking piece attached. Find the retaining tab and push it down while turning the blower motor counter-clockwise to remove.
Adjust the temperature controls to make sure they are working correctly. The dials should have the proper amount of resistance. If these are not working correctly, it may be a fuse problem.
Locate the fuse box by opening the driver's side door and prying off the panel near the steering wheel with a screwdriver. Remove the effuse with the fuse extractor mounted to the fuse box door. Escalade models newer than 2000 models will have extra fuses in the door as well. The fuse in an Escalade that controls the AC is number 12.
Check to make sure the dome lights and graphics display are working properly. If they are not, then it may be a control panel problem.
Remove the entire trim plate on the dashboard by easing it out with a screwdriver one edge at a time. Unscrew the control panel and gently ease it out before unplugging the electrical connection.
Touch the control cables to make sure they are regulating the temperature correctly. Find them while the control panel is removed. One should be warm to the touch and one should be cool to the touch. If they are both warm, then this is the problem.
