Hello;
Have your heater core backflushed. These vehicles use DexCool and they clog up terribly. The DexCool antifreeze does not mix with anything so you will need to flush the system. Hope this helps.
Thanks;

My 97 cadillac deville over heated 1 time on the highway. after filling it with coolant i dont have any problems. why did it overheat that 1 time


if you are using coolant that is mixed 50-50 with water, the water will evaporate. If you are having issues and using straight antifreeze without a water mixture, you may have a small coolant leak or a small leak in the head gasket.

AC and blower sometimes does not come on immediately, Info center reads check coolant but coolant level is fine. Any relationship between the 2 issues??? 2001 cadillac deville


No coolant has to do with heat. freon has to do with ac. Now when you said your ac AND blower doesnt come on right away are you saying it does this ONLY when its on ac or when its on heat too. I would first change out your coolant level sensor or add coolant (which you said was fine) and see what happens. but im sure they are not in relation as the blower motor is on its own circuit

Hello my friend has a 1995 deville that wont heat. He thought the blower was bad so we put a different on it and wired it to run with the key on. It runs but will not blow air into the car. None of the...


If the blower was working why did you replace it?
Heat is made by the engine, and then it is sent into the heater core and a fan, blower motor, blows heat into the car.
First - check that the coolant level is full. If not add MIXED coolant.
Then drive a few miles for the engine to get hot.

If coolant level is full, the thermostat might be bad, or the heater core might be plugged.

I have a 97 Plymouth Voyager and I don't get how air. How can I fix it? Can anyone help me?


check your coolant level. if its too low, coolant may not flow through the heater core which heats the air from the blower. also, if your thermostat is stuck closed, the same thing would happen. if your coolant level is fine, you may have to take it somewhere to check the thermostat.
