2000 Chevy Silverado doesn't blow air on any settings

No heat or a/c blows on any settings in my Silverado. I have replaced the resistor, the actual panel that the switch is on, and the blower motor....at this point I can't think of anything else besides the connector with the seven wires on it to replace, but as far as I can tell the wires aren't burnt and the test light says its getting power and ground all the way up. Any possible solutions....Thanks!

The only thing I can think of is, try replacing the relay switch for the blower motor, you replaced everything else, and you didn't mention that. I'm not saying this will work, but it's the only thing that's left.

2000 Chevy silverado 1500 blower not blowing


there are two or three things to check first the fuse in the fuse box next there is a resistor that controls the fan speed that will go bad and last the blower motor itself if you can get to it you can run a twelve volt source to the hot or positive terminal and it should come on if it is still working .

This model has a weak connector on the blower resistor. Remove the hush panel on the passenger side and disconnect the resistor. Look for signs of melting on the connector plastic near the ground terminal. The resistor may also have failed. I have the wiring diagram somewhere if you need it.

Air and heat dont blow hard any more


Sounds like you have a bad blower moter resistor.
The resistor assembly is located on the heater box module
under the dash near the blower moter. Hope this helps.

2000 silverado a/c only works on high fan speed. Blows ice cold. But lowering fan speed, or adding heat to adjust temperature causes compressor to cut out.


Hi! The blower resistor is the culprit here,located on passenger side of vehicle under glove box area. I have replaced several of these for the same problem. You also need to check the connector for the resistor for heat damage to terminals and replace as needed. The harness will come with wiring attatched and heat shrink **** splice sleeves. hope you find this information useful!

Heating Problem w/2000 Plymouth Breeze.


Sounds exactly like what my mom's car was doing as for the blower only working on high. It was the resistor... I assumed it was the climate controls and replaced them but it didn't change anything then i thought that i must be the blower motor and replaced that too but it turned out to be the resistor which is under the dash on the passenger side of the car.
