I sprayed some cleaner in the connector, and probably should have put some dielectric grease in also, but I used an electrical lubricant spray instead. Reassembled and it works like new.

One word of caution, the motor assembly is marked "Dispose of if Droped", so don't drop it.

Step 1. Remove the running board from truck, 4 13mm nuts and 2 13mm bolts unplug wiring.

Step 2. Remove motor cover. 2 small torque screws.

Step 3. Spray lubricant behind the circuit board to lubricate transmission.

Step 4. On rear of the hinge there is an 8mm bolt remove it and knock out aluminum wedge. Remember which way it comes out. That wedge is a keyway that makes the board move with the motor shaft.

Step 5. With the wedge removed, spray all the moving joints with lubricant and work the hinges up and down, until everything moves freely. Working the lubricant into all the joints.

Step 6. Install wedge back into place; install motor cover back on to motor. ( Make sure that the rear bearing is aligned to accept the motor shaft. you might have to wiggle it back and forth to seat the cover. Plug in wiring harness and try it out, then install it back on truck.

Very simple and easy to fix. It probably will take you less that 1 hour. I will post pictures this week when I do the other side. The side that I repaired deploys up and down twice as the other side now.

- You save a bunch of weight

- If you can get same year/model - it is a bolt on
- Existing holds underneath make it somewhat straightforward

You did a great job showing how to fix the problem, I followed the steps with no problems...except one (and it's a biggie). After putting it all back together the board works opposite from how it's supposed to: when the door is open, the board goes up...close the door and it goes down. I tried disassembling it, rotating the motor manually to the opposite position, reassembling etc...but it does the exact same thing. Any ideas would be greatly appreciated.

I have read in other posts if it is just one door, that sometimes you just have to spray WD40 on the door switch but on my 04' Navi,there are no switches exposed and mine doesn't work with either door anyway.

I got underneath and found a wire coming down out of the floor connecting to the floor board mechanism. I cleaned the connection with spray electrical cleaner but it did not seem to help.

Anyone have any other ideas?
