Just replace the acctuator on the drivers side of the heater box, you can buy the part at almost any parts store its three screws and one electric part. if i remember right the socket is a 7/32nd or 9/32nd. dont plug it in until its all bolted back on.

A/c and heat dash vents won't work but all others are fine


check the actuator motor on the heater sounds like the motor is not directing the air as it should. The motor is in the center of the truck inside attached to the heater and has arms on it to move the heater and ac doors.

The fan motor on my 2001 silverado 2500hd only blows thru the defroster and feet ports and not straight ahead


Vent ducts are controlled by vacuum valves, listen for suction sounds from the dashboard while moving though zone selections. If heard replace bad hose or repair the current hose.

I drive a 2004 silverado 1500 and the 10A fuse keeps blowing for the vent selector. It'll get stuck on one mode. (Either defrost, or feet, or something). It on its third fuse in a month. The AC works...


Sounds like a bad actuator, the actuator is a small motor used to control a door in the heater box, there are a few doors to control temp of air and then one for mode (location of air blowing out ) and one for recir. try to locate and unplug it and replace the fuse and see if that stops the fuse from popping if it does then replace the actuator.

02 SILVERADO. AIR ONLY BLOWS OUT DEFROST VENTS. REPLACED CONTROL PANEL. NO LUCK


I had a similar issue on an 05 silverado. Air would only blow out of defrost vents. But this worked for me:

1) Unplug HVAC fuse for 10-30 seconds
2) Start truck
3) A/C comes out defrost - wait about 10 to 15 secs
4) A/C then starts coming out the floor vents for about 5 seconds
5) A/C then starts coming out the dash vents.
6) While the A/C is coming out the dash vents, turn A/C OFF (otherwise it cycles back to defrost for good).
7) Turn truck OFF
8) Restart truck and it should work fine

(Found solution on another forum from user "ccurran")

My Defrost doesn't work


Check to see if the duct hose to the defroster vents has come loose. If air is blowing out under the dash when you have the control set to defrost, then this is likely.

The fan/blower only works on the high setting.


It probably is the fan switch itself. They are around $30. for a new one. You can take it out and check to see if you have power to all the settings with a ohm meter or test light. They are not real hard to take out.

Heating/AC mode door does not move2004 Silverado 1500


If it is a ATC automatic control temperature , you will have to find the code. if it is vacuum controlled you will have to check the vacuum hoses that control the mode door. maybe something fell into the defrost vents and it got stuck. the only solution for that is to try fishing out the object through the vents..
