Did the window motor thermal bypass...OMG do they work better.

Re: Did the window motor thermal bypass...OMG do they work better.
Since this thread was brought back from the dead, I thought I would post this. I just bought some ACi window motors from AdvanceAuto (part number 82460 w/ lifetime warranty), and they are quite different when you pull off the cap:
As you can see, this appears quite a bit different than the photos posted previously in the thread.
For starters, you can remove the cap without having to deal with the commutator armature & brushes. Second, the thermal switch* seems completely different. I'm tempted to install this 'as-is' since the engineers may have fixed the "slow assed motor" problem, but this new design would at least simplify the thermal bypass mod -- it'd take 2 seconds to bypass it.
*-I'm assuming the orange piece in the cap is a thermal switch.

Re: Did the window motor thermal bypass...OMG do they work better.
I just finished this, and saw no improvement. I soldered a heavy gage wire across the strip, and the motor works virtually the same. The downward motion is slow, but it is also working against the spring. The upward motion is working with the spring, and goes faster then down, but about the same speed as before. I also tried this with the motor out of the car, to see if the auto down feature was shut off by the thermal resistance thing. The motor keeps trying to roll down, no matter what. As long as the motor has power, it will roll down. I had the whole window assembly out. Crank, gears, spring, and all. So the auto down feature is here by confirmed that it is not shut off by the thermal resistor.
How ever, why did I not see the faster gains others have?

Verify that the switches are working correctly with an multimetter, check voltages.
Maybe the motor does have some damage.

maybe you just have high expectations

here are some more pics, a very easy and very rewarding mod! and auto-down still shuts off by itself somehow... i replaced the thermal resistor with speaker wire..

It appears that you are soldering a short in place of a suppression capacitor. Since the capacitor is across both brushes, it is unlikely that this motor will run as no current will be available for the armature.

Im not sure what it is, plus I dont like the new motor. It appears to be the normal motor found in cordless power tools.

Re: Did the window motor thermal bypass...OMG do they work better.
My driver's motor really needs this mod! My pass window has always been slow but I've never tripped the thermal limiter. The driver's window wasn't bad, but all of a sudden, it won't go up on its own without stopping. I don't think I'll bother with relays, though I might (if convenient) measure the voltage at the motor while it's operating to see how much it would benefit from relays.

Re: Did the window motor thermal bypass...OMG do they work better.
It is possible that the yellow part is a re-setable fuse. They are fairly new and would work better in this application than the copper strip. They contain a polymer that expands after a certain amount of current and effectively turns them off. Once the load is removed and they cool off, they turn back on. A motor drawing too much current (like one pulling a sticky window) would cause this to happen.
