see if you have power to the switches. if you don't, check the plug behind the kick panel, see if there is power there.

i dont have a DMM to check if there's power

Harbor Freight sells them for a few bucks or just get a test light for a few bucks...Tj

You'll probably want to get one, or at the very least a test light. Coming from someone who worked their way through a number of typical XJ electrical issues, they're sort of notorious for electrical problems.

VOMs and test lights are cheap when compared to taking it to the shop.

A 12 v light bulb, some wire and electrical tape works in a pinch too.

Are you able to use the switch on the rear door to roll down the DS window?

mine does the same thing. Was told by jeep mechanic that jeeps are famous for this.

The way the circuit looks, it would be unlikely that front and rear driver side switches would fail at the same time... It's more likely that the two switches in the driverside door would go because of water damage or abuse.

It's a critical TS fact of weather or not the rear switch still works??? Make sure that the lockout switch is not on and try the rear window switch in the back door...

Did he bother to share the fix with you or was he just willing to point out the obvious?

if its not a fuse its mainly plausable that the switches are bad , i work in a shop and come across this alot even on newer vehicles

The way the circuit feeds this... Pretty much a givin that the DS front window switch is bad, not the wiring.





The rear window motor gets power 2 ways:

1. From the front DS window switch through the rear DS switch. (If the window functions normally from the rear switch, the front DS switch for the rear window is likely bad)
2. From the lock out switch (vio/wht wire) in the front DS door to the rear DS window switch. (If the rear DS switch will not work either, that switch is likely bad or the wiring from the door jamb to switch or switch to that motor)

I don't remember if the 88's switches were all interchangeable but if they are it is easy to comparatively TS by taking a known good switch (from the Pass side windows) and put it into the DS where you have the problem. Be very carefull because the switches are held into the Bezel with very small/fragil clips that are easy to detroy or send flying off to never land...
I have had good luck with reusing the clips (that don't get away) by lightly crimping the hooks that hold them in place.

Check wiring between drivers door and body they break here a lot.

put manual windows in

on a serious note
i didnt see anywhere if you know for sure if your motor is good , unplug the motor itself and going into it there should only be 2 wires , get a good 12v source , either a battery or a jump pack works great , make 2 wire leads , hook them up to the 12v source and touch the prongs for the motor and see if the motor works before going and tearing thru all your wires in the door , this will proove for sure if its the motor , if the motor works then you have wireing issues elsewhere
