A/C systems are hard to diagnose without having access to the vehicle. One of the most common problems is undercharge (Not enough freon in the system) indicating a leak somewhere in the system. Other causes could be a burnt A/C compressor clutch fuse, defective compressor clutch, defective compressor/belt, defective High/Low pressure switches in the system, defective evaporator icing switch, defective wiring... Basically, you're better off getting the system diagnosed by a good A/C knowledgeable mechanic...

2000 caddy Seville ...after starting and engine warm turn on the heater and it blows cold air. Fan works / waiting for hot air and then all the sudden it kicks in. Engine at normal temp


Low coolant, if there is an air pocket in the engine it will make it to the heater core. Once there , the air coming out is cold/cool. Once the coolant fills the heater core, it gets hot. If the coolant is fine hot or cold, then have the HVAC system scanned.

The passenger side air temp control has a problem. Check connections at switch. If you have a volt meter you can check the switch for continuity or ohms of resistance. No continuity, replace switch.

99 deville,cold air on pass. side warm on drivers side


There should be a nozzle on the left passenger side that has blue for cold and red for hot so if there is a light on the nozzle all you have to do is turn it to cold if you want it cold. Caddy's have dual heat so you can change what you feel coming out push the nozzle in and the light should go off. Therefore making the car on the same hot/cold.

1999 cadillac deville air wont work


There's a blower motor (fan) under the hood and up against the firewall near the center of the car that takes some work to remove. It has gone out in the last 2 of my 4 Cadillacs. Turns out if you're not real careful with the positioning of the spark plug wires they will brush up against it, and if one of them gets cracked or brittle it will "arc" and short out the blower motor. The a/c compressor should still come on (you'll hear a click when it engages) but you won't get any air blowing into the cabin, hot or cold.

The part was like $200 stock (year 2000 prices) and it took about an hour to remove it. My Caddy at that time had this damn strut bar going across the engine bay which we eventually removed to get to the blower motor.
