Air Conditioning problem
1994 Ford F150 Two Wheel Drive Automatic 150000 miles
----------------------------------------------------------------
My 1994 Ford F-150's air conditioner blows hot air. Tried re-charging but got a warning that there were other problems. Has R-134, but won't take a charge. When turned on air blows for a short time, then a vacuum sound of a door shutting but no cold air on any setting.
I don't have the $$ to go to a shop right now so... help with advice on doing it myself would be great. Thanks.[img:30ddc4d263]http://www.2carpros.com/forum/automotive_pictures/225729_pocketorangecorrsmall_1.jpg[/img:30ddc4d263]

remove ht ecovers to th eunder sid eof th edash and see if you can find the door that is shutting.It may have a leaking vacuum diaphram on the blend door, and that can keep it from staying ont he cold setting. Does the compressor ever engage? If not use atest light to see if it is getting power. What are the line pressures ?
