Default A/C AIR CONTROL-blows warm air

I have a 97 se. It doesn't have climate control but it has rotary ***** that control the fan/temp/a/c,heat, defrost. My air condition lines get ice cold in the engine compartment but the air coming out the vents is about 65 deg. Actually, The air is colder at the driver'* side vents than the passenger side. My Haynes manual only shows the controls for a manual slide control. I could not locate any arms or doos to see if maybe one was stuck and not letting cold air in. The a/c was working great as I just had it serviced. I've got to go out of town tomorrow so any help would be appreciated.

OK, nobodies answered me which seems unusual on this site. I have read many post I found searching the site but they seem to all deal with systems with ECC. I don't have ECC! Can someone point me to a post that covers this? Does it have a vacuum tank like the ECC system does? Please help!!

The airmix actuator test still works the same, its just the actuator is a different part# for the manual control than the ECC. Test your airmix actuator and if you see any odd movement the its time for a replacement or redneck fix.

Why was it serviced, what was the problem???

a good indication of only cold air on one side means your under charged,
what'* happening is your evap. is only cold half way up instead of the whole
thing,,,, not saying that'* your problem but.....thats one good indication.

it'* possible you still have a slow leak..

The reason I had it serviced was because I had installed a compressor, evaporater, & oriface tube/dryer. After I posted on Sunday, I was checking my vacuum lines and noticed my compressor wasn't engaging. I took it to the shop & they said the compressor is leaking at the seams. Unfortunatly, I bought the compressor a while ago so it isn't under warenty. I'm probably going to just let them fix it ($411.00) so i'll have a warenty on everything. Thanks for the help.
