Thank you John. First thing I thought of was the compressor. On this vehicle, the compressor is in a bad spot to see but I will look again. But if the compressor wasn't running all along why would there be such a sudden surge of cold air? If the clutch wasn't engaged and then engaged I would think t...

Times to start are random, could be up to hour or more after ac turned on. Very cold air starts suddenly, seems to run indefinitely while on trip but not tested on very long trips.. Engine off, not restarted for awhile, may or may not come back on right away.so cycle begins again. Once when cold air...

Latest update: The car was taken to a professional. He attempted to charge the system and found same condition as I did: Could only charge the system partially.

Thank you. I hate to say it but I may have to give this to a professional. My time for my own repairs is very limited these days. I do know you guys will guide me along the way. As for the sealant, I do not think I have used much other years. I do know that shelves seem to be loaded with r134 with s...

The r134 was pure. A second can I tried did contain sealer but almost none of that ever got into the system. I will toss that. Actually very little of either can was taken in. Also I tried two different charging kit cables and the gauges behaved identically in both- going into "overcharge"...

I have a 2015 Hyundai Santa Fe with about 160k miles. The A/C system has had a very slow leak for several years. If charged in the spring, I could get well into summer and fall without recharging. Recharge was just attempted. Attaching the meter/r134 to the low pressure side and shaking the can back...
