Sounds like the reverse switch is bad.

 

Go to the TDS site and read their instructions about the pull down hatch. Most common problem is stripped gear nut. Been there and done it.

 

Agreed. "motor keeps running" = "broken gear nut"

Check the Tech article I wrote on TGO for instructions on repairing the 1986-87 & 88-91 hatch pull-down units.

Stuck down without the motor running could be a bad reversing switch or more likely the unit just needs to be re-set. The pull-down unit only runs on the down cycle if the striker-sensing switch is pressed. To re-set the pull-down unit is simple. Just reach down into the hole that the latch portion retracts into and press on the striker-sensing switch. That switch is located just in front of the latch as you face the pull-down from the rear of hte car. Presing the switch SHOULD cause the motor to turn on and power down until the reversing switch is tripped. You'll hear a CLICK when that happens. The motor will turn off at that point. Release the switch and it should power all the way back up and be re-set. There are seversl reasons why the pull-down unit needed to be re-set . Most commonly the hatch hook contacted the striker-sensing switch but failed to be latched. The pull-down started it's downward cycle until the hatch closed. At that point the motor continued down but the hatch hook came off of the switch. The motor stops immediately. Re-setting as described is necessary at that point.

88ttopta needs a new gear nut. I just listed the instructions for re-setting the pull-down unit for anyone else that needs to know.
