I have a 99 q45t ac gets cold then warm. Replaced ac compressor had the system evac. no leaks refilled, same thing. Noticed when I'm on driving above 60 it gets cold, but @ lower speeds warm air. Any thoughts??

If air isn't being pushed through the condenser, it isn't going to be cooling down as nicely.
Also, there should be some electric fans in front of the condenser that turns on when you turn on the A/C, see if they're working.

The fans are working almost to hard. Engine temp is perfect, I'm hoping it's not a bad ac compressor. It took a lot to get in.
