SOURCE: 99 STS AC is blowing hot air

I had the same problem but it was blowing hot air on the passenger side of the car. I assume you have the dual zone controls that I have as well. The problem is most likely the damper that controls the flow of hot and cold air into the car. The motorized component of the damper is most likely not working and its stuck in the hot air position.

I had mine replaced by a repair shop so I cant tell you how to replace it but it may be something that you can do if you have the time and patience to work on it.

Good luck

SOURCE: I HAVE A 1994 CADILLAC STS AND NEEDING TO REPLACE A HEATER CORE

This can be a very difficult repair. If you pay someone to do it, the labor costs are very high due to the amount of labor necessary to even access the heater core. I cannot tell you step by step how to do this. I can however tell you that you will have to remove enough of the dash to allow access to the core. Go slow, be careful and do not break any of the parts. Use common sense to figure out how the parts come apart. Look for screws and clips. Some plastic parts just snap together. Take digital photos as you go along to help you in reassembly. It is just a matter of getting to the core and removing it. Of course you will need to drain and flush the cooling system, replace the thermostat, and add a fresh 50/50 mix of DexCool & Distilled water after installing the new core. Be sure and set the heat to high when pouring in the fresh coolant. Bleed all air from the system.

there is a vacuum actuated valve in line from the engine to the heater core, right on the firewall. a lot of times it is removed for less restriction. if you replace it and the vacuum lines are in tact it will cut the flow to the heater

I have a 2001 cadillac sts and it only overheats when the ac is on why?


The AC sheds the heat from the passenger compartment through the condenser (which looks like a second radiator), which is in front of the engine's radiator. That “preheats” the air that pulls heat from that radiator.

If the radiator has all it can do to shed the engine's heat using the air that is at ambient temperature, preheating that air will push it over the line into overheating.

Additionally, the AC removes the heat in the passenger compartment through the work that the AC compressor does. The AC compressor gets that power to do that work from the engine. This in turn causes the engine to work harder, creating more heat to get rid of than when the AC is off.

If the coolant is old, replace it.
Ensure the belt is tight enough on the water pump.
On many cars there is an electri fan that comes on with the AC, mounted in front of the condenser. If you have this, ensure it is operating.

A.C compressor reads off on my dash. Also I refilled my refriderant and it didnt work. I own A 97 Cadillac Seville STS.


If it builds up too much pressure in the system it will shut off compressor. May be an AC pressure switch problem if compressor does not even come on.
