Read the BAC output at the ECU- the duty cycle should increase big-time (voltage will fall a good bit at the pin) when the A/C is switched on, if it's working...

It does? I know the 89 FSM has that info, but not my 88. It's the copy from iluvmyrx7.

OK, OK, I admit I don't know where I got this sheet of paper. I don't really remember where I copied it from. It's been laying around for a while. It's page F2-75 and is out of section ....CONTROL SYSTEM F2. And a subtitle OUTPUT DEVICES. I assumed it came from the 88fsm that is online. Must have been the series five I got it from. Don't know. It is informative though
