Air only works on high

I have a 2003 Chevy Silverado and the air will only blow through the vents when it is turned all the way up on high. Otherwise, no air comes out at all. Help?

Your blower resistor is bad look under rt side of dash by the blower motor you will see a flat plug into a piece bolted in air box this is the resistor. the wires are bad about burning up also un plug and check that if so gm sells a replacement plug. sometimes you can clean if you caught in time

When i turn my A/C on it blows hot air and there is a leek on my pasenger side dash board. what is it


Had exact same problem with my 2006 Chevy Silverado 1500. Would blow hot air thru drivers vents only and sometimes if I turned truck off and restarted would blow air conditioner for a bit. Rec'd recall letter from Chevrolet in January for this problem.

2003 Chevy Silverado ac bashboard vent not blowing.


There are controls in your car where you can control the flow of air to certain parts of your car. Make sure that you have it turned to where it blows out of all of the vents and then the air should come out of the dashboard. If this continues then there might be a ventilation hose that has been disconnected and is not getting air to that part but the other hoses are still connected.

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")

Relaced battery now vents don't work


There is a flap in the venting that can stick. This vent is contolled by a vacuum operated actuator that may be leaking. This actuator has a vacuum hose that runs to the contol panel. Check the vaccum lines hear as well.

It sounds like the HVAC head needs to be recalibrated, most likely when you unhooked the battteries you lost the memory to the control head, it's in a default position/state.

2003 chevy silverado air does not blow through vents. Condenser works. Pipes are cold. Fan works. Modular (next to fan) repalced to get fan to work. Heater air conditioner controls under radio replaced....


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.

I have a 2003 chevy silverado that is blowing hot air through the vents when the temp is set at its coldest setting


check under the dash to see if the blend door is operating, this ian internal door between the heater core and the a/c evaporator. also check that the drain hose from the evaporator make sure its clear and water is coming out of it,otherwise the evaporator will freeze solid and therefore no cold air
