I am a proud owner of a 99 GMC Yukon 4x4. Its has a little lift, nice big tires, headers and dual exhuast. I freaking love it!
I have a PROBLEM though....my ac and heater sux! The heater only works when I am going 70+ mph and only is hot for maybe a minute. The ac does the exact same thing. I have put freon in it...nothing happened. I changed out the Heater Valve...still no heat. Then under the driver dash I found that the Blend Door Actuator arm was loose so I put the little plastic deals and spring bake in the arm...again nothing. No heat no ac. It blows great though.
Im so frustrated with this i went through the winter with no heat and now summer time I need ac.
Please help me out!
