I jumped in the car and took off the other day. The windows and door locks were working fine when I parked the car but now all of a sudden...nothin'

I checked the fuses, they are OK. I checked the door connectors, fine. I even tested the windows by applying power directly to the wires at the plug; motors work fine.

Anybody had this experience before?

Have you checked the switches themselves? Maybe the harness got unplugged.

I am not really sure but I think that there is a power window and door lock relay. It should be located in the same spot where the other fuses are.

yeah, I checked the switches. Both are OK. The thing that is irking me is that BOTH are not working. Which means that there is a common flaw...something both windows need to work.

Relay? I don't know. I don't have schematics handy. Maybe the main power junction box? I'll keep poking around.

The locks have a relay. The windows do not. The pdl relay is located in the passenger kick panel. There is a ground connection for it. See if the is screwed to the kick panel.

Each (I think) is powered from the junction block which is fed from circuit breakers in the fuse block. The PDL relay gets control power from the CTSY fuse.

Toddster,

Any luck on your problem?

they shouldnt have a fuse. Should be a metal circuit breaker in the fuse box, not one of the colored plastic fuses. They unplug just by pulling them out too.

No luck yet. I ran some continuity tests and everything seems OK. I feel like Geordi on Star Trek, "We should be going like a bat outta hell Captain".

I'm going to have to pull the dash...rats. I hate it when it gets hard.

Unless you burned something up I don't see what you'll learn by pulling the dash, unless you just want a better look at the junction block to see if something has come loose. I believe you can see the junction block from up top if you remove the driver's side speaker.

The Pwr/Assy circuit breaker feeds power to the PDL via the heavy gauge orange/black wire to the junction block (white rectangular box just below the windshield to the left of the driver's side dash speaker, bolted to the kick panel).

The WDO circuit breaker feeds power to the windows via the heavy gauge pink wire to the junction block.

Be sure that both the heavy gauge orange/black wire and the heavy gauge pink wire are solidly connected to the junction block.

Have you checked both circuit breakers? It would be a coincidence if both circuit breakers blew at the same time but it could happen. As Roger mentioned the circuit breakers are silver rectangular cans slightly larger than a fuse and are on the passenger side of the fuse box just about in the middle of the box. They simply pull out like a fuse.

In case you don't already know, you can squeeze the two plastic tabs that hang down slightly on either side of the fuse box to release it. The fuse box will then swing down for easier access so you can view the fuses without having to lay on your back underneath the steering wheel.

Do you hear the pdl relay clicking when you try either switch? It gets control feed power from the ctsy/lid fuse via a small gauge orange wire. This orange wire has a splice (S-125) in the cross car harness somewhere above the steering column.

Keep us posted on your progress.

Good luck,

Carroll

Many times the wiring the windows and pdl will get broken where it goes thru the rubber bellows between the doors. If you find nothing else......check there....common problem. Good luck.

OK, here is a progress report that may interest you all.

I finally had to tear out the dash board and trace every single wire to it's point of origin. I did continuity tests on all switches, wires, and tested the motors with direct current (10amps). Everything checked-out OK. I was on the verge of insanity until it occurred to me that I did my continuity tests with a standard multimeter that puts out about 100ma. Window circuitry is designed to withstand up to 30 amps so I tried testing everything at various amp levels. SURE ENOUGH, the passenger switch failed continuity as current went above 10amps. I replaced the switch and viola, the windows work again.

But the power door locks still do not work and I do not see the connection between their failure and the window failure. I can only assume it was some sort of power surge. I don't know how or where it could have come from since all of my fuses and fusable links are OK.

I've checked the relay amd wiring for the door locks, I have a feeling that the one of the solinoids or switches is cactus. I'll keep you posted.
