Folks, I've not found anything on here that describes the problem I'm having.

I bought a new motor and regulator for my tailgate in my '78. What's strange is I can test the motor by itself (runs both directions). However, when I install it in the regulator, it won't run either direction.

I'm just running wires straight to the motor like I did initially, but the motor will not attempt to turn.

I get that it might not go one direction, since the regulator is in the up position. However, it won't even try to lower the regulator.

Almost seems like the regulator spring is way too strong for the motor to flex it, but it appears that it's not even attempting that.

Anyone run into this? Bad motor, or am I missing something obvious?

Thanks in advance for any advice.

Jim

So are you saying the motor is not strong enough to operate the regulator.?
When you test the motor is it in the wire harness or are you just putting power to it on a bench?

That's what I'm guessing. Motor is not strong enough.
I'm just testing this on a bench to make sure it works before I go to the trouble to re-install.
Just running power to the wires of the motor. Works fine in both directions when not installed to the regulator (regulator is mounted to a bench), but won't do anything when installed to the regulator.
So, motor works, but.... not enough power?
Just curious to see if someone else has ever experienced this. Motor is from LMC.

That’s strange. It does not even try.?
Maybe it’s not getting adaquate ground being it’s not mounted to the tail gate
If it were me I would try it in the gate before I call it bad
Verify it’s getting power in the gate with a multimeter
Then if still nothing condem the motor
It’s not too hard to do and the regulator needs to go in anyway.

No, ground was fine. I'd already verified. And the reason I was doing this was to avoid to going through the trouble of putting it in and then finding out it didn't work.

However, I found the issue this morning. Loosened the motor a bit to see if it was binding, and that was it. For some reason, I did not have it aligned perfectly in the regulator.

Had to flex the arms just a bit to get the motor teeth aligned with the arm teeth, bolted it back down.... and now it works.

On to the next issue.

Nope, they don't. Thanks for the ideas.
