The air conditioner in my 96 LTC blows nice and cold until about 10-15 min's after the engine warms up.
Upon a cold-start, I turn it on, w/ the EATC set on 60. The compressor immediately kicks-on, runs for about 5-8 sec' then switches off for 5-8 sec's. It does that four to five times before the comp. runs continuously, as it is supposed to do.
The black cylinder that's next to the coolant reservoir-- the condenser (evaporator, maybe?)-- Whatever it is... It becomes cold to the touch, and
*Condensate builds-up on its outer surface, as it is supposed to.
So, after 10-15 minutes, the compressor will shut-off for 5-15 secs, then kick-on for 5-8... And just keeps going through that cycle and the inside air quickly becomes warm.

> I recharged the system about three wks ago, and it does blow noticeably colder... When it's working for that 10-15 minutes, that is.
> I am unable to get the EATC to enter test mode. Pressing OFF & FLOOR simultaneously, then while holding those two buttons down, pressing AUTOMATIC is supposed to do it. Am I doing something wrong?

*Just a little fun-fact: Contrary to popular belief "condensate" is the actual water itself that forms on the outside of a container which is colder on its inside, than the outer air temp (a glass w/ ice in it, for example)--
"CONDENSATION" is the
process which causes the condensate to form. [I didn't know that 'til recently(!)]
