a/c problem part #2
Ok I hope this will help me out this is what I have I found outso far with the help of sonma_zr2 maybe some one can help me out further on what to do next.
With out jumpering any of the sensors key in run postion engine not running I take and ground the ground wire on the relay the one that gets the signal from the pcm and it engages the clutch. This also works with the engine running. So now I know the circut is working and I am not getting the correct signal from the PCM to turn it on.
What can I do know to narrow it down?
Bad PCM?
Bad sensor?
This is what I know about the switches.
cycle switch up on the accumulator.
Switch between the radiator and the pump if you jumper the connector it tunrs on the fans
There is a 2 plug connector on the back of my a/c pump but I do not know what it it does.
then of course the power plug for the clutch coil.
Which switches could be bad or which ones do I need to jumper to by pass for low to no coolant?
Could my a/c and heater controler in the car not be telling the computer to turn the air on?
anyone know anything else for me?
Thanks

this is the same problem we had with Nate'* 95. We stopped at this point not knowing how to procced. I think he actually had pressure in the system, just couldn't make the damn thing run. even forcing the ac clutch while engine running still wouldn't cool.

Well I am getting 12 volts to the line switch that is between the compressor and the radiator but that one turns on the fan?
I am guessing that one is not the low pressure switch?
Is the low pressure switch on the back of the compressor?

Since we're not getting to the bottom of this, I'd like to suggest you find a local A/C shop and get it tested. Down here, most places will charge you a $25 diagnostic charge if you don't get it repaired there. At some point it makes sense to pay that much in order to find out what is really wrong, IMO.
You can then do any repairs you need from there.
