So I got the remain bit of 134 removed my my AC system. I read up on the instructions and proceeded to try to refill with Duracool.

Connected the gauge to the low side and stated the engine with the AC on MAX.

Screwed on the can and inverted it and turned in the knob to puncture the can. The gauge went upto 60+ as expected then climbed to 100! and nothing was happening. The compressor was not engaging so I tried bypassing the switches. Sometiimes it will come on for a second or so.

The gauge just stays at 100psi. Nothingis being transfered.

I closed the valve on the can and pulled off the hose set, gauge still at 100psi.

My coach had a 134 adaptor, so I tried changing it to the new one in the kit... no difference.

Its like there is a one way valve holding it in at the coupler

What am I doing wrong?

Thanks
