1987 150 electric windows

Fuses of the same amperage can be temporarily borrowed from another fuse location if a fuse goes out. Replace the fuse as soon as possible.

This Ford F came in with three complaints. The power windows do not work. The wipers do not work and the interior lights do not work. Figuring that they were all related I decided to test the easiest system to access, the power windows. No power. I then went to the interior fuse box and removed the battery saver relay. It is the small relay second from the top left corner. I checked for ground at the upper right hand terminal by first placing one lead of my voltmeter to a positive battery source , 0 volts, bad.

That in itself is enough to show that the GEM module is faulty but I also looked at GEM data with a scan tool and saw that internal system voltage was 22 volts. Hard to do with a 12 volt battery. Diagnosis of a faulty GEM module. To see how to replace the module please click here. This is the reading with a new GEM module across terminals 85 and Just like it should be 12 volts. Another important note is that I asked the customer about water leaks on this side of the truck and also closely inspected everything as I disassembled looking for signs of water intrusion.

Water leaks are a big problem with these modules. One, you could apply 12 volts to this wire with a jumper wire.

Two, you could jumper terminals 87 and 30 together at the battery saver relay. The second will also test the wiring in the door jamb as well. Sparky and community. I have an issue that I is baffling me. I have a 97 F extended cab with the power windows. My most sage advice is not really only look in the diagram, yet understand how the constituents operate when inside use.

Before reading a schematic, get acquainted and understand each of the symbols. Read typically the schematic like the roadmap. The best method to easily instal cables is to be able to straighten them out first. Amperage Rating or even Amp needs in order to be checked for all electrical wiring and devices. If it's blown, replace the fuse. A blown fuse can indicate increased power draw due to a binding or worn mechanical component, so you should continue with then mechanical repair process once you replace the fuse.

Remove the door panel. Check the electrical input on the power and ground wires, which are generally the two largest wires connected to the window motor. Attach the multimeter to the wires, then activate the window switch with the car's key in the on position.

If you are getting power in both directions of the switch, then the electrical wiring to the motor is good, and the motor should be replaced. If you are not getting power to the motor wiring, then you need to check for power going to the window switch. Did you make this project? Share it with us!
