Rep Power: 283 A/C Problem
2002 Honda Civic HX, 215k miles on body, swapped engine to JDM at 180k miles.
The A/C is blowing hot air. I got a can of 134a refrigerant to refill it. The can has a pressure gage on it that reads from 0 kPa to 80 kPa. I turn the car on and put the A/C to full blast and leave the car running. I open the hood and attached the can of refrigerant to the low side port. The pressure gage immediately spikes off the chart beyond 80 kPa. I can tell that no refrigerant is leaving the can because the can is not turning cold.
Any clue what this means?

If you think a good mechanic is expensive, try hiring a bad one

You need to pursue electrical stuff instead.
When you turn the AC on do the radiator fans kick on?

Re: A/C Problem
Wait wait wait..... google converter says 80kPa = 11 PSI?
You SURE your gauge reads in kPa?

Re: A/C Problem
80 is plenty of pressure to get the system to start operating.
Disconnect the 3 wire connector from the compressor, and ohm test between the outer two red wires. There should be continuity.
EDIT: The center wire operates the compressor clutch
Pull the connector off of the pressure switch, start the engine turn the AC on and check if there is a ground on the blue wire.
