Turn the key to the accessory position and see if the blower / windows work. I'd need to see a wiring diagram for the ignition switch but I suspect it is failing.

Turning the key back and forth a bit might help. I'd also put a test light on a fuse that gets power from the accessory circuit and see what happens.

In instances like this, I've back fed power the supply side of a fuse to see if the circuits are intact. If power is fed to the load side of a fuse and the total loads of other circuits on the supply side are higher than the fuses rating, the fuse may clear so pulling the fuse first is a better strategy.

Loving all these suggestions guys - thanks again.

Temperature is supposed to get above freezing next week (heat wave coming !) - can't wait to get out and give these ideas a try.

This sounds like a good step to try.

Partial Update ....

Damn near froze my fingers off, but managed to check all the fuses and they are all good. Played with the ignition switch and got no results either. However, did have a look at the ground terminals behind the air intake box. They are covered in a nice even coat of green, so they are obviously suspect. Will give those a good cleaning when the feeling comes back in my fingers !

The Power Window Switch and the A/C Heater Control switch share the same ground circuit G203. The air bag control ground is G202.

You might want to check the ground G203 to see if there is bad contacts at that location.

On mine the ground wires corroded away from the eyelet. Ended up putting 3 or so wires per eyelet and recrimping, there are about 20 ground wires between both sides. Be sure to scrape the wires clean and check the grounds on the passenger side inner fender area as well.

Even if doesn't fix the blower issue, it will save you from other ills like no fuel pump. headlights, turn signals and more since everything not inside the car uses these grounds.
