I have a 96 Chevy Silverado with a 4.3L v6 (210,000miles) and the blower motor only blows on the floor and the ac wont work i tried changing the mode door acuator -(don't know how to spell that)and that didn't change a thing my ac is charged but it won't allow the compresser to engage. I also replaced the heater switch and that worked for about an hour then something smelled like it was burning and it quit working

I see this question has been asked a few times and nobody responds to it. Why? I know somebody must know the answer because to many people have had this problem when you do a search.

I am having the same problem. 1996 Chevy Silverado/K1500. I noticed it starting making a thumping noise whenever i turned my truck on a couple months ago and then last week I started it up and the directional controls wouldn't work. It just stays blowing on the floor. The heat works, cold air works, the AC won't work because I can't get it to blow out of the dash. You said you fixed the problem, so I hope you see this post and can let me know what it was/is.

Thanks
