Allegedly the driveshaft shop was going to work on getting me a working driveshaft today but TBD since most of the Dallas metroplex is closed due to yesterday's sleet and overnight freezing temperatures.
I did have the opportunity over the weekend when it was 80 (gotta love Texas weather) to do some other work on the Bronco.
One issue was the rear window wouldn't roll up or down from the switch. Initially, I checked the fuse but all the power stuff (power windows, power locks, rear window) are on the same fuse. On the '88 there is a diagram on the panel when you remove the fuses that will tell you what is what and which fuse controls which functions. It will be pretty obvious when a fuse goes because you will lose a lot of functionality at once it seems.
Anyhow, on the window. I removed the handful of screws keeping the back panel on and was able to access the motor. However, I found it was easier to work with the tailgate down. I unbolted the top, lifted it up a little, and had a buddy fold the tailgate down.
Note: There is no support for the window, no frame, etc. So Be sure to put something under it to support the window just in case.
I found that my rear window motor has been replaced before and someone had messed with the wires because there was some clipped wire and mis-matched color wires in the tailgate.
My test using a portable jumper battery was to run a wire to each side of the motor. There are two wires and which side is the power wire determines if the window goes up or down.
Keep in mind there is extra wiring running to the key to control the motor going up and down. I have to tackle that part next but don't assume its the motor without testing the switches and running current directly to the motor.
