Replacing turn signal switch on 2000 Jeep Grand Cherokee 

Glad it helped

Well, I missed on that one, it was the flasher the whole time. If it was a customer's car, they would have had that part installed no labor charge.

@@57bagre Can't get 100% all the time.

That should be a quick part install (if it fits!) I should not have to work it in my schedule, should just do it when it arrives, weather providing.

Weird problem. I'm thinking maybe corrosion between fuse box and connectors behind it, like maybe the fuse box outside? or could rain be getting in under the windshield and onto the inside fuse box. Let me know what it turns out to be.

@@57bagre I will pull fuse box off and check tomorrow. Inner is clean and dry. I've disconnected all the lights and nothing. Still glows, still makes reverse lights and right turn signal light up when I turn on left signal. Right side works fine though.

What about the wire loom from the inner fuse box to the tail lights that runs down the driver side floor board under the carpet on a car, (and under the cab and down the frame rail on a truck) could that be damaged? but you said the heater fan not working, this wire loom would not effect the fan is why I suspect the outside fuse box.

@@57bagre you know I haven't checked that yet, could be salt and snow got into it. We had gone sledding and we were all snowy and wet. I'll have to pull those out and check for cuts in the wires or possibly connector. And its my defrosters that caused the heat to pop a fuse. If I hit my defrosters it makes a click and my turn signal light brightens then dims. That would run back with that same cluster of wires wouldn't it? For rear defrosters?

I think you have a good place to start running down that trouble. Let me know how it goes.

Not at all! Now if I was in a curve and I didn't straighten the wheel for a split second as I hit the bump, then I would expect it to shimmy a bit. Interesting you should ask as I am setting up to do an upper ball joint on the GMC dually as I write this, I just came in to grab the camera. I better also show how to check the front end before I tear it down.

@@57bagre I have been in one that did it and it's far worse than I expected. Almost as scary as violent head shake on a motorcyle.

That's dangerous! I'll definitely show how to check the front end. Maybe a different video since it is a safety issue for those who don't know how.
