I just had the evaporator replaced and the A/C was working
well until I went on a road trip. It seems to be very cool
when starting but after 20-30 minutes at high speed( 65-75 MPH) the air from the vents slowly warms up. I have brought the car into the local lexus dealer and they say everything checks out. Can compressors freeze? or is this possibly something else. Thanks
