Hey guys I just purchased a 1994 bonneville ssei. I just had all the a/c done and it was working great, well a couple days ago i turned a/c on and only hot air was blowing out. The compressor kicks on and everything and i have all the right pressures so i know i didnt leak any 134a or anything. Doesnt matter what temp you set it at, still hot air, im assuming its the blend door actuator but im having trouble finiding it? What do i pull out glove box, actual dash, etc? Thanks for the help

My Riviera has 5 of them. 2 behind the glove box and 3 under the column. I would try to find a factory diagram to see which actuator controls what.

Have a looky here and see if this might help...

Thanks guys! Sorry for the late reply... It works when it wants to now, it'* winter so heat is the issue but I went the link mike sent and found some stuff that may work!
