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,
