Question about 1998 Cadillac DeVille
The system blows, but the compressor never kicks in. No cold air. There are no refrigerant leaks. How difficult is it to replace a compressor? Will I need to replace all the system Parts?
Generally speaking if the a/c clutch doesn't kick in it's because of either no voltage or low refrigerant. you can waste the money and just recharge the system and replace the a/c clutch, however it's been my expeirience that often times the compressor goes bad and that money was needlessly spent. this time of year the price to fix the system is far cheaper than the begining of the spring take the vehicle to a qualified a/c tech and your problem will cease. if you have no voltage that means the a/c clutch relay is bad. make sure all relays and fuses are good. the relays are clearly marked. quick to find out is to switch the cooling fan relay with the clutch relay if the a/c kicks in you know that relay was bad. hope this helps
