When the air conditioning quits working on your Chevrolet Silverado pickup, the first thing to do is to open the hood and verify that the compressor is properly engaging. A compressor that won’t engage can often be fixed by a home mechanic for a very small cost by checking the electric components and refrigerant level. More serious issues must be handled by a trained technician.
Fuses and Relays
The first thing to check if your compressor will not engage is the electrical system. Check the fusebox first, which is located under the hood near the driver’s side fender on 1999 through 2010 Silverado model years and on the left side of the instrument panel on older models (refer to your owner’s manual). Locate the red 10 amp fuse marked A/C COMP and remove it. If the metal ribbon within the fuse appears burnt or broken, replace the fuse. If the fuse is okay, the next suspect is the air conditioner relay.
