Default 13 F-150 burning smell from ac vents

I tried searching and saw some people said they had this issue but never the fix. So when I start my truck a burning smell, like plastic burning comes from the ac vents. Now it's doing it more and more and not going away. Tonight I pin pointed it to the truck doesn't even have to be running. Just turn on the blower motor and bam smells like my trucks gona burn to the ground. I'm guessing blower motor or blower resistor. Anyone else have this issue and find the fix? I hate the smell of burning plastic. My truck also sits a lot but that's nothing new. I'm about to try and find the blower resistor and see if it smells burnt I guess.

If anyone else has this problem, it's for sure the blower motor resistor. Smells like it was about to burn the truck to ground. 40000 miles and already shot. Not impressed.

Harness first, I change the Harness that connect to the module, and fixed it. I you don't do that the module will fail again.
