My H1 CTIS failed in the worst possible place. Tires deflated to 15 psi on Washington coast beach. When it was time to go back, compressor kept pumping but at the same time deflating of tires was taking place.
SO here's what's going on. With engine running I selected front tires and pressed compressor switch to inflate. I can hear the compressor operating but at the same time the air escapes. Switching to deflate and than back to inflate doesn't make any difference. Switching to all wheels or rear only has no effect. Can someone help me.

Thanks,
Paul
