After searching 13 pages in Villager, and 8 in Quest, psmith22 has the closest to my problem, but request any and all to assist me.
I have 2001 Villager, front air blowing warm. Underdash controls work appropriately, along with temp control. Saw them physically move. Rear air works great. Compressor cycles on/off every 20~30 seconds. Compressor relay obviously works, but also switched with another to see if it was faulty, same cycling. Checked pressure of 134, steady around 45psi. I added more and got up to 65, but no difference in temp out of vents or compressor cycling. When I disconnect, then reconnect gage, pressure reads 45. Also bypassed high? or low? switch on dryer bottle, and with compressor running for a few minutes straight, no difference in vent temps.
I think I have a blockage in a line somewhere. If that is the case, how do you track it down? This van has just under 100k, and no accidents.
Is there anything else that can be checked? I have a pretty grumpy wife right now.
