Update!!! Shortly after I published this video one of my viewers wrote to inform me he has had success by sanding the carbon impregnated rubber rather than re-coating them with conductive paint. Because I have seen some remotes which no amount of cleaning could restore, I don’t believe that will work in every case, but I thought it was important to add his suggestion. Please read his comment in the comment section of this video.
Here is a link to my updated video.https://www.youtube.com/watch?v=_znMPaZYZAc
————————————————————————————————————-
A gentleman came in my shop with a door and window lock control panel from his 2006 Hummer H3.
After looking at the circuit board I realized it had the same problem I’ve seen many times with television remote controls. The conductive surface on the rubber pad had worn off, so I recoated it with some conductive paint also known as conductive glue, and that fixed the problem.
Because I’ve seen some of these repairs come back needing a second coat of conductive paint, I was wondering if anyone viewing this video knows of a longer lasting conductive paint than what I’m using. I’ve seen youtube videos where some people used small pieces of tin foil which they glued to the rubber pad and that seemed like a better option than conductive paint, but perhaps someone watching this has some better tips they would like to add to the comment section of this video.

Bare conductive electric paint; subscribed today as well thanks! if my MacGyver fix stops working i will have to decide between $11 paint or $22 part:). https://amzn.to/2TGJ9U8
Thanks for the video! my 06 H3 74k miles driver window and door locks stopped working. I rubbed the pcb board contacts with 1500 grit paper and that for now fixed the driver window and door lock. Interesting to me: the door lock chimed when I pushed lock but the locks did not move
I have hummer H3 06 that the module allow the windows to roll down but none of the lock will unlock or lock
Can you show how you open that to get to that circuit board because I can't seem to open mine there are two little red knobs on the inside and I'm not sure what they are I took off the three screws
what is the easiest way to access this part? Do I need to take the entire panel off? if so, how? If not how?
I have a question. My door locks and windows work fine on my 2008 H3. But the switches no longer glow. It has happened to both doors and the temperature control knob and air flow knob (I'm not sure what to call them). How do fix it?
Liked Shared and added to playlist. Hope you have a very prosperous new year.
I have used that paint before, but don't remember the brand and found the same result as you where it does not last very long. The foil idea sounds like it might be worth a try.
OK, here's hoping you take this as the constructive criticism it's intended to be. While that paint works well on the contacts of the PCB you really shouldn't be using it on the rubber pads for remotes or as it turns out, car in-door controls. The thing is that the contactors on the rubber part are infused with carbon and only need to be buffed off with a piece or paper. If you take normal notebook or printer paper and wipe it across the carbon pads it takes the shine off them and they usually work fine after that. I learned about this back when I still had an original Nintendo as the controllers would fail from heavy use. It works like a charm every time.
The contacts on the PCB are a different story entirely. They paint that stuff over the PCB contacts so it doesn't gloss over the pads on the rubber part so much creating a longer lasting device. I just thought I'd clear that up to save you some headaches later down the road. I'm sure I don't have to tell you what a mistake a layer of conductive dust is for electronics so I'm not going to say anything more about that. As for this video, well it's "diversify or die" right? I can definitely understand why your working on door switches. Happy Newyears and cheers man.
liked and shared. good job
guy with diamond rings and hummers he can afford to get new parts
