This was a HUGE problem for these cars. YOU can not fix it. Back in the day, we had to take them to the dealer, and they would send them back to the factory to be repaired. It cost quite a bit of money. It is pretty rare to find one at a wrecking yard that is anygood.
Yes. Optional on the LE
You could have shorted it out. I have a digital instrument cluster that has shorted out in the displays and the rest of the dash went with it. I've been looking for a replacement for 4 years and still haven't found one. Good luck.
Take it to a mechanic.
above the front floor hump under the dash (cliped onto the plastic) (below the radio) real easy find and fix
under the gauge dash
you gotta take the dash off to get to them :)
caused by leaking heater core not radiator heater it is under the dash hard ot get to if the leak is not to big use radiator stop leak otherwise fix is going to be big bucks
dash lights relay
It is under the dash at the steering column.
Dash speakers are 3 1/2 inches. They are a real pain to replace. You need to remove all lower portions of the dash.
buy a new horn and install it
on my 88 it's under the dash in the middle, you can see a small flap. 85 and 88 should be similar
