Tried to attach a print of the wiring diagram for the HVAC on my '93 C2500. In it you can see connector C209 and what looks like two GM part nos. for each connector half. 12034481 and 12034482. Did a search and keep getting a msg. saying not a valid GM no. on the internet. This connector is buried behind the HVAC control panel and that panel kept blanking out and finally quit. Pin 150 carries all the ground current for the cont. panel and the blower motor and it had become contaminated with the green cancer and overheated. Melted a large hole right in the middle of the connector. I did a good repair on that wire and had to bypass that line away from the connector. I'd like to keep this good old truck in it's original condition as much as possible and was wondering if anyone knew of a source for GM connectors this old? I figure a junk yard part will likely be in similar 27 yr. old condition.
