part three.

Can I jumper the single wire leading to the compressor to 12VDC to cause the compressor to run?

I would like to at least acheive a complete fillning so I know the rest of the system is functioning and can cool the car.

I can then track down the continuing fault(s) pressure switch, or bad wire or A/C compressor relay?

P.S. I would help if I could find a complete schematic showing the A/C system components and locations.

part two:

I then connected a 134a container which weighed 17.40 oz with the fitting and after opening the can (which was upright) and the gauge high and low valves and the quick connect valves the system began to fill. The 134a container began to cool, I had about 40 psi I think the filling soon slowed, and after about 30 minutes I knew no more was transferring. I then closed the high side quick connect valve and the high side gauge valve. I have my assistant start the car and turn on the A/C. I expect the compressor clutch to then kick in and the compressor would then aid in the rest of the system fill. HOWEVER, the evil compressor will not engage, so I can fill the system any further.

My questions now:

Is there a pressure sensor or switch somewhere which is falsely preventing the compressor clutch from being engaged?

If you are on-line now maybe you can help:

Thanks for the advise guys. I was not trying to run the compressor with the vacuum connected. I had connected the vacuum pump as suggested to evacuate the system, It immediately brought the low side gauge to full vacuum, I let it run for about an hour. I then disconnedted the vacuum pump, by removing the center yellow hose from the vacuum pump and attaching it to the center secondary fitting on my gauge set. I then opened the low and high side quick connect valves and the low and high side gauge valves. there was a quick sucking of the yellow hose air from disconnecting it and then the vacuum stayed at greater than 29mm Hg for at least 30 minutes. This told me there was no large leak.

Gloyle,

Hey, thanks for your help last week on my '93 Loyale needing to find the ECU test connectors. I have now purchased a Chiltons manual, it didn't have that info in it. I now need to replace the outer boots FWD only, and replace the hood cable. The manual shows enough for the Boots but should I try replacing the boots after dissassembly and inspection, or just get rebuilts? I also will need to get the AC working, any advise?
