its possible because i did unplug the fan that wasn't working and plug it back in.

i also had another thought and i don't know if it could be related, but the previous owner put LED lights inside of the headlights, like a cheap AUDI impersonation or something. The right head light LEDs quit working for a few days so I traced the wires and kind of tugged on them and they worked after that. i really have no idea what kind of mess they made with the wiring or where it actually goes or what it is hooked to. she also had LED lights in the interior that weren't working. i was able to get those to work and put them on a switch so they weren't always on. i never use them, i just wanted to see if i could get them to work properly.

another clue might be the DIC going out. i wonder if there is a fuse in the unit itself. the fuse in the glove box for it is fine. but it quit almost simultaneously with the car running hot. that happened once before but i just unhooked the battery and hooked it back up and it was fine after that.

maybe there is just some wack wiring going on with those headlights, or an exposed wire touching something somewhere causing all kinds of silliness.
