Got a volt meter? Check and see if you are getting 12 volts at the connector for the compressor clutch. (probe both wires, only one side is hot, the other is ground, ground the meter at the battery.....)
Heyyou
I put the gauge on with engine off I got 85 psi. Started engine and the compressor kicked in (that was a surprise) it pulled down to 25 psi. What does that mean now.
Ah, still low on charge. There should be a chart on the can, that will show pressure you want, in relation to outside temp. Charge to the correct pressure for current temp, and you should be golden.
