You need a rear window motor for the tailgate window. Take the rods out of the doors that run the power locks, then you can at least lock it manually.

As mentioned above, be sure it IS your motor bad before buying a replacement. many things can cause the rear glass not to function properly and one of the most overlooked problems is simply the striker bolts which are the studs on the interior of the rear qtr. panels, if the plastic bushings on them have cracked off the tailgate wont actuate the safety switch properly thus not allowing the window to operate. the motor may just need a gear/clutch kit for around $12 which consists of 3 plastic rollers and a gear (most auto parts stores carry this repair kit) i have even seen them fixed with 3---1/4" nuts...

power door lock solenoids are $$$$, and a pain to replace, may want search your local boneyards.

Thanks for the tips I am sure it is the motor it trys to go up but is too weak. Comes down fine.
I just unhooked the PDL and use it manual.

Bronco90, if the motor tries and has trouble going up, you'd be well advised to try the cheaper bushing kit mentioned above. BTDT on our own Bronco 90, F-150 P/U and, Merc Gr Marq several times in 300M miles.

The reason it's too weak to push up the weight of the window is because the friction surfaces of the plastic (nylon?) bushing in the kit are too worn.

Now if the window is stuck down so as to not allow access to the wiring, switch, and motor etc, motor shows NO sign of activity, amp gauge doesn't flinch when either switch is tried, fuses have been checked, door latches all check out"I'd" appreciate knowing what should be my next step.

But, if your motor still show life and the window will move, you still have hope. Be sure to lube the window channel too to decrease the work on the motor both now and in future.

Hope this helps.

Now can someone help me with my edition of this type of problem?
