Removal of turn signal switch 1986 pontiac parisienne

Turn wipers to off then turn the car off. We have the same problem in our 1986 Pontiac parisienne brougham

This sounds like that actual turn signal switch assembly. To replace it you must remove the steering wheel and disassemble the column a little. This takes some special tools and skill.

look for signs of a windshield leaking water into fuse/relay box- located near pedals under dash. Also remove small plastic trim below steering wheel ( 2 screws) and unplug black connector with 6 or 8 wires directly under steering column. Turn key on if wipers are stopped then your switch is bad- steering wheel must be removed to change switch.

Sounds like a bad turn signal switch because, the brake lights also run thru this switch.

The ignition switch is on top of the steering column. You will have to remove the trim piece under the steering column and then loose the 2 bolts (1/2 inch) that holds the steering column. Watch your shift ind if it starts to move you will have to unhook ( silver or black clip with a small cable attached to it). Make sure you unhook the battery and block the wheels to keep the car from rolling. The switch uses the same bolts and the dimmer switch. Remove old switch and install new switch.

remove steering wheel, lock plate and directional switch. then you can access the ignition cylinder
