Tail gate regulator lift motor

[Wonderwagon]

Want to move and test the motor that actuates the regulator attached to the tailgate window.
12v battery battery, negative lead attached to the regulator frame/ sub- assembly. Positive lead connected to one of the two needs from the motor. One lead up the other lead down?

Thanks

Don't thing so. The motors that are in the doors are tested by: One lead to one male part of the plug, the other to the other male. Should go up. Reverse the wires, should go down. Don't see any reason why it would be different on tailgates. Smarter minds than mine can tell you what it's called. Reverse polarity? Cam

The outside of the case does not need to be grounded.

You apply positive to one lead and negative to the other. The motor will go one direction.... Reverse the polarity and it will go the other.

Was afraid of that, tested as your saying. Hoped I did it wrong, only other thing is using a 12v battery with about 8 ah, May noy have enough current with the cold and thick grease. Thanks for the quick reply. Will remove the motor, and get it and the regulator out for clean up as i set out to do.

What Big John said! I have never spent any time on a tailgate window, as I don't have a wagon, but looking at other posts here, the pw motor looks to be somewhat more robust than the regular window motors, due to the size and weight of the window. I don't know what the regulator looks like, or how the tracks that it must slide up and down in are situated. In my car, there are plastic rollers that guide the regulator up and down the tracks, and these rollers can break up, which causes the window to jam up. You should take a look at those too. Also, is there a relay for this motor? Might want to investigate that too, make sure it is not rusted and it is grounded well. Just my thoughts. C Shaft

Most also have a safety switch that can be bad, prevents the window from working if the tail gate is down.

So, the tailgate motor uses a chassie ground. Took one lead of "shotgun" energizer. A 12v battery with a momentary switch in series. With two alligator clips on the motor end. Grounded the negative to the regulator frame mountin stud, had shiny metal threads for good contact. The other went to one of the motor leads, being challenged, started with the ("Red" in correct) Dk Green motor lead arms went down. Switched to the black and the arms went up. So chassie grd it is.

When the manual says right side opening, I forget its when your looking at the sheet metal or passenger side, it's 17 inches compared to driver 14". The latch assembly needs to be removed prior to the regulator/ motor assembly.

Arms need to be in the furthest up position, pulling the assembly to the passenger side access hole. Rotating it down, once the roller reaches the upper left corner. The motor will just clear, kinda rotating it down and pulling it out to clear the other roller. Rotating the whole thing counter clockwise, one the arm and motor clear the acess hole.

It's cold out when it's 20 with the wind brr. No pics to cold.

That surprises me... All the other window motors don't need to ground to the chassis.

Sorry.... I should not have assumed they were.

What year car are we talking about here... I have to go look at a wiring diagram now.

69 plymouth wagon. When I looked there was no grnd symbol attached to the motor. Just the two leads one through the limit switch tied to the Brown at the key switch. The other Dk Green connected to the yellow wire back to the key switch as I recall. Red home runned? I'll look again as well, outdoor xmas lite time.
