My dash air became inop because of a plugged thermostatic expansion valve. Classic symptoms were very low suction pressure and very high high side pressures with no cooling. Simple diagnosis but not so simple of a fix.

First challenge is to remove the old TXV. In my 99 it is in the bowels of the lower dash area. I finally gained limited access by removing both the HWH control panel and the rear view monitor. After evacuating the system, don't snigger I have a reclaim unit, I removed the TXV.
