electrical problems....please help

[mydelsol]

I have a 90 tsi awd and i have no dash(guage) lights or instrument lights. they just wont turn on at all. i have checked fuses under the dash and under the hood and they looked fine. also my fog lights dont turn on. my heat wont blow any air either. when i turn the knob the fan turns on under the hood, but no air comes out of the vents. when i bought the car, it had no radio and it has an aftermarket alarm hooked up, but it wasnt used in a long time and i didnt get a remote for it. i have researched for hours and found that usually when the fuse goes out, the tail lights dont work, but mine work fine including the turning signals. i found some info that the dimmer for the dash can get messed up and prevent the lights from coming on, but i dont know how to check my dimmer out for malfunction. any help is appreciated. thanks

replace the the dimer switch. it happened to me...friend was replacing my stereo and shorted everything else out. i replaced it for 10 bucks (salvage) and everything works fine now. other friends old nissan did the same thing as well.

Yeah dimmer switches go bad. Or there may be a short somewhere in the wiring. Get a voltmeter and check to see if any power is getting to the dimmer switch.
