1980 - plastic connector on A/C compressor - Diode???
The plastic connector broke. Went to the parts store and found one that has s diode in it. I don't know if the old one has one or not.
Does a 1980 need the diode?
If so, why?
Will it hurt the A/C compressor if I use the connector with the diode?
Thanks.

There's a diode on the wipermotor connector, not on the AC pump I think. At least I never saw it... are you sure?

I'm not sure what year they started putting the diode there. I don't have one on my '78, but ksems has it in his '81.

I think it is there so that when the compressor kicks on it doesn't feedback into the system (I think).

I checked *removed the AC stuff) my compressor has the diode too :)
Never noticed that before, then again I don't care for airconditioning. ;)

Thanks for the info guys! I hope someone with an 80 can check and let me know if the connector has the diode.
Marc78: Thanks, I read that post and it does not contain the answer, it was more about the compressor connector. That's the post that got me wondering about the diode.
Twinnie: I like my A/C. :yesnod:

kgraumann:
I mean the small black plastic connector on the top of the A/C compressor that has a black and a green wire coming out of it. This plastic connector may or may not have a small diode between the wires. Mine does not and I want to know if this is correct and if it will hurt anything if I install a connector with a diode. Thanks for checking.

Thanks for checking kgraumann!!! :cheers:
GM must have started using the diode on the 1981s. It probably has something to do with the ECM (computer)????.
My question now is, will it hurt anything if I install a connector with the diode? My guess is that it won't but I'd rather be safe than sorry.
