The heater uses water to deliver heat and the A/C delivers cold with freon. If you have no water, the heater valve is stuck, or your heater core is plugged, you will not get heating but your A/C will still work just fine.

SOURCE: 2003 chevy silverado air does

The air vents are control by vacuum line and or linkage.

Listen for hiss or feel for vacuum leak under the dash,

Feel for broken linkage(s) that are close to the vents.


WORK BACKWARD if you have small hands to feel out where is the missing link.

SOURCE: Heater and Air conditioner does not go on. COuld

Could be a fuse, but try it all the way on high first. If it works on high only, it's most likely the resistor in the fan control. Hapened to mine a couple of times and Chevy charged me about $150 to fix it.

How do I change a rear heater core in a 1999 chevy suburban


go to the parts store and get a service manual for this truck as there is a specific procedure to bleed the air out of the heater core or it wont work... also this isn't the easiest thing to do, especially if it has the rear air option as well

I have a 1994 Chevy Silverado and every time I turn on the ignition, the knocking noise begins from under the dash somewhere. If I remove the fuse to the a/c/heater it doesn't make a sound when I


Try starting the truck so it makes the noise.
Then switch the air control to "fresh".
If noise stops, it is probably the motor that closes flap to recycle the cab air.
It would be found under the dash, under the glove box, & would need to be replaced.

2004 CHEVY SUBURBAN FRONT A/C WORKS BUT THE REAR DOESN'T TURN ON


There is a blower motor control processor for the back blower - it takes input from the front control and the rear control and decides the fan speed. That processor could be faulty, or the blower motor, or a 30amp fuse in the engine compartment.
In the front system you have a controller and blend doors that direct air thru the heater core and evaporator. You would need to check the operation of those blend doors.

Air conditioner


You are saying the blower motor stops when the truck stops moving ?
Or the blower motor doesn't work and the only air you get thru the vents is outside air when the truck is moving ?
