My connector on the wiring harness is melted and does not fit on the switch well. I have the whole heat/ac system working properly now but the connector and wire leads at the blower switch look like crap I believe related to a fan relay failure which I have corrected. No fan switch or fan relay when I got the truck, just crappy looking wiring. I see one sponsor sells a reported replacement connector but it does not look like it will fit. Anybody know a part number or a source for this. It's got factory AC.
