1989 Ford Bronco Other - Windows & Glass

Question: My rear electric window is stuck in the down position. Previously to this it was stuck in the up position. I sprayed silicon on the large gears in the center and managed to get it to go down. Now I hear no motor noise and the window does not go up. The fuse seems fine. Where is the switch mechinism located on this model (what has to be depressed to allow current to the electric motor---trip switch????)......sometimes I had to apply pressure to left corner to get window to engage...please help.

Technican: Do you hear the relay click?

Owner: I hear no noise of any kind. I am using the key in the rear door to activate the window. Nothing happens at all. No click, no noise, no movement. Is there a button of some kind that depresses when the door is up that may not be working properly. I had problems in the past with this but put pressure on the door which made the window go up. Where is it located. What can I do to fix this problem?

Technican: I've found from my years at a Ford dealership that this problem is most commonly caused by the key acuator.I don't know what kind of conditions you drive in, but where I'm at, there is big dust issue.You need to pull the wire running to the motor with the gate down and jump direct power to the motor.If nothing happens by switching power left to right, then yes you have a bad motor.If the motor operates the actuator is at the key area.You also stated that when you applied pressure to the gate, the glass would sometimes work.You need to check both latchs and clean them and make sure they fully engage with the striker bolt.The striker usally has a plastic collar on them.If this is worn, the latch is not making a full lock which will also not allow the glass to operate.

Owner: I did as you said and pulled the wires and applied direct power to them. The window went up/down dependent on positive/negative power. So the dc motor is fine. Both the left and right latches do not have any type of plastic sleeves on them; just bare metal. How does the latches affect the powering of the window. Is there some type of sensor/switch on them??? Now about the key actuator I observed from the inside a left and right button and I could manually push either in. But when I did nothing happens. So how does this actuator work???

Technican: When you turn the key it ativates the up/down buttons.With the key in the on position, check the power wire going into acuator.If you have power going in, next dissconect the power going into the motor add check for power here while turning the key in the gate.If no power then yhe acuator is most likely bad.The latches themselves on some models act as a secondary safty so you can't open the gate with the glass up.The strikers fall into place by assuring the lock is in the full lock position.And yes, some are all metal, while others have the plastic sleve.Check for any unusual wear.If you had no power going to the actuator, check power to the interior switch. Paul

Owner: Just one last question. As I am a novice not a mechanic. When you say the acuator. What is the Acuator (location, etc). Is it the same mechanism as what I am sticking my key into? When I turn the key it moves a metal arm onto a button and depresses it. Is this thing with the buttons the arm pushes in the acuator or is the acuator something else in another location? thanks for all your help.

Technican: Yes this the acuator.Check power into and out of it.8 out of 10 times this is the problem. Paul
