2017 EL: blower motor resistor problem

[Millerwelds1]

I've replaced two of them since January, and the last one I replaced just went out today. I'm using genuine motorcraft part. Just wondering if anyone else is having them same problems.

Also, it seems to happen when the A/C is on high when starting the truck.

Have you taken it to the Dealer for diagnosis? It sounds like something else is causing this to fail repeatedly IMO.

Did you replace the wire harness as well?

No I have not replaced the harness.

One of the wires was melted and I spliced this in and have had no issues since. I did not replace the resistor.

What make model is yours?
Thanks

I'll check out the wires.

So I got underneath and saw the wire that was getting hot, cleaned the contacts and plugged it back in, started the truck, turned on the A/C, wiggled the wire a little and it came on and off with different positions, so I agree it is the wire not the resistor. Thank you for the help. I'll be ordering a connector or replacing that wire.

Had the same problem, you have to replace the wiring harness as well. There are two green looking cables, don’t mix them up.
