2003 Blower motor resistor and harness

A while back I replaced my blower motor resistor and it came with a redesigned harness via amazon. See attached pics. It took a dump and I'd like to go back to the original harness. I'm not sure what resistor, harness pigtail and wiring diagrahm I need to reconnect it all. Anybody got a link or access to the correct part#s? Thanks

So what happened it melted? One of those wires looks awful small, may have caused an overheating condition. GM makes the appropriate repair conector.

No, nothing melted. Just went tits up and I need the proper replacement.

All of the resistors I find have a 7 pin connector and my harness has a 5 pin connector.

A 10 second search brought up S916 from Orielly. Its the 7 pin harness.

Ok not sure how that helps when I have a 5 pin harness? A search under my VIN shows a 7 pin but that doesn't make sense. On top of that the connector to the blower is a different size.

Re: 2003 Blower motor resistor and harness

Well your post confused me. You say it came with a redesigned harness, then talk about all the resistors being 7 pin. I read it as you originally had a 7 pin, then got the one with 5 pin and new harness, then wanted to go back to 7 pin.

Anyway, S1619 is the 5 pin connector. You don't have to go through O'Reilly its just literally the first thing that came up in a search.

EDIT: RU631 comes up as a 5 terminal resistor and harness. Oreilly has it in stock in your area for $77.

If you want to keep looking search for Sierra 5 terminal resistor. You'll get better results.
