This was my exact issue after I figured out that the hot wire going up to the 30 amp fuse in the engine bay was melted. I cut that wire off and extended the wire to the positive terminal of the fuse block stud. I added a 30 amp fuse in line and the fifth setting for the fan speed worked great. After that, I checked the wires again at the blower motor resistor and found the same issue that you had. I appreciate your video. You did a great job.
So wait even though you might of like me bought another resistor and after market 3 green thick wiring kit just for the radiator to the fan at Orielys this after it had melted the plug into the resistor etc. My a/c 3 months later still doesn't work like it did now it does have 260k miles but I've got all new everything radiator fan clutch water pump etc. so if I do the ground thing it's gonna be the fix all problem of problems?
Update. Forgot i made this vid. Glad i could help everyone. And no . I never had any problems after this . My ac worked for 3 years and then sold the truck
I'm willing to bet all you would have to do is tighten the grounding screw on your frame and maybe clean it with some sandpaper and that will probably stop happening
I'm on my second resistor, and I thought that the fan itself was drawing too much amps. I definitely noticed the melted Connection in the plug. This was going to be my next try. So you grounded the motor itself in isolation of the resistor bank? I got to watch more closely. Thanks dude..... okay it looks like you made a bridge. So it can ground either way. Correct me if I'm wrong before I catch my truck on fire
That black wire goes on up & grounds (gm didn't do a reliable ground) so he cut it & extended the wire to ground it up front right side using a screw to the frame to get a better ground. In turn it stopped the over heating. The old ground he just left, it's useless.
If you haven’t changed the blower motor it will continue to fry your resistors and wiring. As the motors age the brushes inside wear out and require more amperage which causes the problem.
At Full speed fan , it should bypss all the resistor circuit, or at least close to zero amps should flow thru it - having better direct and lower resistance route to reach motor

does it work on all speeds?
Yes! But I had to bypass the ground wire going directly onto the blower motor itself.
Best advice I've found yet. I'm going to definitely try this fix

Did it help

This works excellent!! Thank you so much!
You’re a genius 👍🏼
just did what you did works mint, thanks bud
Was it hard do i have to plug in the connector after or leave it open
What wires can I hook to bypass the resistor
Did the fix last? Thanks so much! Sucks Chevy won’t correct this issue.
Mines doing the same thing. Thanks for the fix
How’s it working?
Is it still working as it should? Been thru this about 11 times also!
Fuse would have been good but awesome. Was wondering why they wanted a new harness with the resistor

Were you getting water inside where the resistor mounts? I'm having the same issue but water coming in and frying it. You can smell the wires burning
Same thing with my 2000 Jeep Cherokee. I replaced 3 heat resistors already

Best fix
You couldn’t show us where is the other end of the black ground wire so i dont get it just run a wire to the plug and the fram thats it ?

I added a 2nd ground wire and the wires are still getting warm not super hot
I did this it worked great.
I am about to do the same thing with my Avalanche. How has this been working long term? Thanks for the vid👍
It still working good?
Dos it matter what color wire i use i only have red ??
Color doesn’t matter, you could always wrap it in black electrical tape if you want
Hi did it give any problems after that
No

I did that and my blower wont tirn off
Sounds like the ON/OFF switch is wired into the ground rather than the positive 🤔.
What is the make and model of your vehicle?
