Default heater and turn signal problems

hi everybody.
i was wondering if anyone else may have had this problem.
a few days ago, i was driving my '89 with the heat blasting when all of a sudden the fan blower sopped working.a little down the road i noticed the turn signals not working.now i've noticed the interior lights not coming on when i open the door.the hazards are still working.i tested the flashers on the fuse box and checked the fuses.there was also an inline fuse below the blower motor that is good.
any ideas?

It maybe one of the fusible links has fried. All of the links come off the large battery terminal on the starter relay located on the right inner fender behind the battery.

Each wire will have a rubber bead on it. Grab the bead and give it a light pull away from the power post. if the wire stretches it has fried. There may be visible heat damage to the wire also.

It actually sounds like 2 separate issues. The dome lights being in there own. Will they turn on with the headlight switch if you twist it?

The blower and stereo sound like you have a bad ignition switch. There is a couple of accessory feeds out of the ignition switch. If one burns out in the switch you will loose just some of your accessories.

It is a little tricky to get to, but if you look on top of the steering column close to the top of the brake pedal, you can see the ignition switch. It is operated by rods that run up the column to the key switch. Look at the connectors and see if there is any melting present from a bad connection.

the dome light doesn't work with switch if its not working, but is still intermitantly going on and off(short in that wire i think). i removed the switch from the 1st solenoid you pictured. i cleaned contacts and reinstalled but no luck yet. i will try ignition switch at work today.

well,i checked the ignition switch and all's well there. got sick over the weekend so nothing then, but when i started short hunting again i noticed an entire side of the fuse box was dead. thats where the fuses are for the horn, wipers, turn signals are.started unscrewing fuse box and what a long screw it was. i'll fiunish tomorrow and if thats not it i'll invest in rain-ex. yeahh!

I figured it out. It is the fuse box.I ran a wire from my hazard lights fuse to the blower fuse. and everything started working. now the only problem is that the blower motor stays on after i turn of the key. the only fix for that is to "jump" to a "key" fuse or replace fuse box.
