2003 GMC Yukon A/C only blows when driving.
My A/C in my Yukon only blows when I am driving. The faster I drive the better it
blows. Any suggestions?
The fan isn't working or is gummed up. Take it to a shop. When you're driving fast, does it make a difference if you turn the air recycle button on or off? They should be able to fix it. My A/C makes a fairly loud clicking noise when it's very hot outside. One per second. The noise comes from the inside near or under the steering column. I'm thinking its a vent door trying to open/shut. It usually stops after about 10 minutes. Otherwise, the A/C itself works fine. I also have a 2003 Yukon STL 4WD
with R134A refrigerant, that is how it works best for whatever reason (when it is driving, not idling).
