Hi there,
This is t he most frustrating problem I've had in years.
My A/C compressor will not engage. On close examination of the CCRM with engine running, fan on high, and a/c on max, I noticed that pin 21 has battery voltage, pin 22 has no voltage, and pin 23 has no voltage. I interpreted that the PCM has found something wrong with the engine and cuts off the a/c compressor.
However, I found that there was some liguid (water?!?!) coming from inside the high pressure switch and misteriously traveling along one of the wires. Is that a bad high pressure switch ? My problem is that I just bought another one from the dealer and it still does the same thing - sweats and the fluid goes down the bottom wire.
Is this normal for a high pressure a/c switch ?
Also, any suggestion on what sensor could be going wrong ?
Throttle position and temerature sensors seem OK when measured Ohm with digital multimeter.
Could it be the MAF sensor or the IAT sensor ?
The self-test codes show 33, 1, 33 and I am not sure what that means either. The only thing I found is that code 33 possibly means "EGR " problems.
Does that make sense ?

Please, any tips are greatly appreciated!!!!
Thank you for reading this.
