'95 88 AC issue.
'95, 88 with analog dash. I had the ac system checked and all was good in relation to pressures and proper amount of R134. The problem seems to be in the heat control. It will not allow cool air to flow thru. I noticed the problem even with it on "vent". Only hot air comes out. I suspect the dash mounted temp control is not allowing the heater control valve to close or one of the duct doors is not operating as it should. When you activate the AC/Heat/Vent control, I can hear the duct doors move. The guy who checked the AC system concured with these possible problem areas. The compressor will come on, but it cycles on and off rapidly. I did a site search but could not find anything on this problem so I am asking for some help here. Its fixin to get real hot here.

Most likely, your airmix door actuator has a cracked or failed internal gear. Does the '95 88 have dual climate control?
Do a search using "airmix+actuator" and you should have all the information needed to have cold air again. Post here if you have further questions and we will try to guide you the best that we can.

Thanks for the quick response and tip on where to search. And no, my rig does not have the dual climate control. Thanks again for the help. I will post what I find when I get it figured out so the next guy will know.

Good point, imidazol. I am not 100% sure, but I believe that the '95 88 had the compressor that cycled, but again, I am not positive.

since he had it checked by an air conditioning guy, I'd think the charge would be okay--but...

My 93 leSabre had the cycling compressor; 98 has V555 which stays on and adjusts the pump amount--unless the low pressure switch would be turning it on and off from an almost low freon charge. which could be this case.
