Refresh my memory - what is the diode for at the compressor?
Posted to HVAC Forum on 11/4/2004 7 Replies

Typically on GM vehicles there is a diode at the compressor.

I've looked in my books and can't find what the diode at the compressor is for.

What happens when the diode is bad - as in open?

Thanks in advance for the answers. Login to read more.
