93 taillight help
 

Ok tracking down some of the quirks to the lighting on my truck. Down to just my front rt blinker not flashing but the parking light part works.

The thing that's tripping me out the most is my backup lights won't go off. They are on constantly. I replaced the boards that the bulbs plug into tried bulbs etc any ideas?

Sound like bulb on front blinker as for backup you might have a broken switch in your shifter

Get a test light and find out if you have power to the turn signal at the light, you must have a ground if the park lamp works. I agree backup lights sounds like a switch problem

Any idea where to find the switch for the backup lights?

not sure but i assume you will have to take the steering wheel off to get to the backup switch

On older cars hey used to have a banana shaped module near the base of the steering column. I think it combined the neutral safety switch and backup light switch. Not sure if it's like this on our trucks but I thought I'd mention it.
