No AC system charged
98 Transport the AC has worked get until this summer. It was serviced back in 05 by the dealership with a lifetime warranty.
I checked the low pressure side with one of those "recharge" cans and it looks to have enough freon. The compressor turns when I hit the AC button but I get no cold air. Any suggestions on where to start? Low pressure is cold and high pressure is hot.

Re: No AC system charged
I rented an air fold manifold gauge set and checking pressures low side is about 30 high side was about 175 buddy of mine told me check the planum for debris and the cabin filters were pretty clogged which I cleaned out last week but I assume it may be more clogged before that?

Re: No AC system charged
Lifetime warranty on an A/C system? Never heard of it!
Your high/low pressures are ok.......is your air temp actuator working? With vehicle at normal operating temp, turn system to ECON or Vent, with A/C off, fan on hi....turn temp lever or knob on control head to full hot.....should get 140-150F with a thermometer in the I/P register....now turn to full cold......should get ambient air temp(temp of outside air).......if you do, actuator is ok......

Re: No AC system charged
From what I can see all of the vents/doors work but still no cold air. I checked it again today and apparently the HP shrader valve stuck open and I lost all of my freon.
 It's off to get diagnosed, evac and refilled. Going to call the stealer tomorrow and see about the lifetime warranty.
