I figured out the root cause of my issue. When the temperature of the evaporator core is nearing freezing, the compressor cycles on and off. I pulled the sensor from the evap core, the compressor no longer turns off and the air is coming out very cold (too cold). I still have to verify the sensor i...

Could your compressor clutch have too large of air gap, even though new?

I've used that aerosol A/C Pro Flush & Clean three times (3 different vehicles) to backflush lines from condenser to compressor (and also the serpentine condenser on one of those). In all cases I used compressed air to evaporate any remaining solvent; I'm in Arizona so that didn't take long. All...

Is your truck regular cab or 4-door truck with dual air? If 4-door, I'd say 1.6 lbs R134a is not enough

Disclaimer - I'm NOT an AC professional. But it seems a good time for a brand new compressor to help with both of your issues, contact board sponsor ackits.com

Cusser I respect your experience and contributions here. My comment about no sight of Teslas in the middle of the day in AZ and NV is sourced from a similar comment by the venerable poster by the name of Bohica [Brad] 2 years ago. I will admit that anyone parking ANY vehicle in the direct sun in su...

There are no Teslas on the road in the summer daytime heat in Arizona I'm in Arizona, and there are quite a few Teslas on the roads here, even in summer. I know 3 Tesla owners and each says the AC works fine. And one friend owns an electric Mustang, says fine. 12V comp will exhaust the capability o...

I worked in an industrial chemistry laboratory for over 4 decades. SwageLok fittings are absolutely the best, and the by-far most-common fittings used in gas (and liquid) chromatography. What that means for us here is that these fittings were leak free for hydrogen (explosive) and for helium molecul...

David - just curious: is this a GM vehicle and the leak on the driver side of condenser?

But I do agree with the point made above. If you aren't having any problems with the system currently, I would leave it alone. Disclaimer: I am NOT an AC professional. I also agree that if you feel comfortable and cool, then the system is working fine, so do not attach gauges or "top off"...
