My mechanic is betting on the blend door. I guess I am skeptical that this problem wouldn't somehow be related to the new compressor work....Who knows, maybe it has been a problem for a while, but not noticable without an assist from the Carolina heat and humidity. Any idea on cost involved in fixing a blend door??
Just for my own education/curiosity, maybe you can help me understand the system a bit better. In the attached jpeg, the ice cold cooling pipe splits into two... the top is very cold, but the other is only slightly cool. Why?
Will be taking it in next week. I'll post an update when the problem is solved.
Thanks again.

That picture helps a lot.. it looks like the low pressure side line goes into a expansion valve and splits off going into the evaporator core in the dash and the core into the rear console. You might have a small blockage on the side that goes into the dash evaporator...you should be able to tell if there is a blockage by checking the pressures with a vacuum pump and gauge set
