no heat or accessorys

[turbo minivan]

so i go out and start my 90 T1 shadow just now to let it warm up (since its winter and the windows are frosty and so on) and it starts fine as always, but when i try my center consol for some heat and defrost, theres no power to the heater switches, no power to the radio, no power on the cig-lighter, no power to the rear defrost, and i also dont have wipers, but all other lights, windows, gauges, power seat and so on all work fine.
i checked all the fuses and there all fine, even the 30A fuse that says "heater/acces". im sure not getting to work without heat and wipers on mornings like this! i drove the car last night at around 6:00 and it all worked fine, heat, radio, wipers, you name it, it was working, then a frosty night and now this? what else could it be other than a fuse? i havent played with anything back there and theres sure no water getting at any wires. anyone have any ideas? ill take it to the shop and check it after work in the light, but i need ideas.
thanks.

There is accessory wire comming off the ignition switch which controlls this stuff. I believe our cars have 2 accessory wires. If this is the case is could be a bad ignition switch. Before you do this check the bundle of fuseable links behind the battery. If these are ok I would check the ignition switch

+1 on the above post.
The ignition switch feeds fuses # 6, 7. 8 on circuit Q20 12 BK/TN.
With the key on test for power at those fuses and be sure the wiring is good and secure on the back of the fuse block.
Tilt and non-tilt are the same.
