BACKLIGHTS WILL NOT TURN OFF

Try jacking rear wheels and rotate wheels if no rotation strip hubs free brake shoes or remove shoes put back together and tow away

If the 3rd break light on the rear of cab works then check the panels where the bulbs snap into make sure there is no corrotion if so replace the panels you can get them at any auto parts for $20. to $40 each.

hope this will help.

yOU WILL HAVE TO PLACE THE sWITCH IN THE STEARING COLUME IT COST ABOUT 90 DOLLARS.

sounds like a bad park pin likely your truck was hit when parked or you park on some steep kills and dont use the parking break and have bent the pin and it is now loose in the hole
the pin is a pressed fit pin and they do come loose

just a little rusty is it ???\

theres a product called release all spray it down the parking break cable ends in the parking break housing
also if need to work asap put truck in reverse and slowely work it back and forth rock the truck

or if all else fails remove tires and wach drums with a hammer untill they release then once open pull the cables with vice grips and have friend pull hand break
so you get a back and forth motion untill cable free remem ber there are 2 rear drums on every truck
so do both cables

There is a plunger on the Brake Switch which is behind the Brake Pedal (arm). This can be checked and adjusted by "unscrewing" the plunger (out) so it makes better contact. Test the brake switch plunger to rule out if the brake switch is bad - and needs to be replaced.

its possible the switch on the e/brake unit broke, take a flashlight and locate a single/double wire that goes to the e/brake assembly (this is the piece you depress with your left foot) and look to see if the wire is broken or the switch the wire goes to is broken.

my eclipse did that. It was the fuel pump. It finally just died one day and wouldn't start back so i would go ahead and replace it.

check the cable you can adjust it under the dash were it conects to the parking brake pedal

Check all the lights, I know on my 85 the circet is open if more then two bulbs are burnt out. As soon as I changed the two bad bulbs the rest kicked in. Didn't make much since but it worked for me.
