Backup lights

Backup lights stay on while truck is on

Backup lights

Postby Bridgerview [OP] » Jun 16 2011, 7:05pm

My backup lights are staying on as long as the truck is running or in the on position. I have a manual transmission in a 04 silverado 2500HD. I have a suspission that it is my backup switch gone bad. Does any body have any ideas or seen this before? How difficult is it to change out the switch? Just looking for ideas on how to fix this issue. Been pulled over for driving with them on, I promised the officer I wasn't going in reverse. Any help or ideas will be very helpful,

Never changed one on your truck but it can't be that difficult. I am guessing the wire colors going to the switch might be green and located on the transmission. Unplug what switch you see and see if the lights go out. That much is FREE!

Tried that and they still stay on. Hoped it was something simple like the switch was bad, just wondering if any one else has had to deal with this before. thanks,

What you suggested, unplug the switch. I can take it apart right where it goes into the transmission. Anyhow thanks for the help, I'll keep plugging away on it to find a solution.

You sure that was the reverse sensor you unplugged? The nature of the switch is such that it requires pressure to make contact (reverse lights on). Removing the wires from the reverse sensor switch will break the contact and make the lights go out.

If you did find the right switch, then there's a short somewhere - that switch should interrupt the (+) side to the backup lamps.

Any trailer hitch wiring work done that caused it? Anything plugged into the back lights (LED light bar, aftermarket lights, etc)?
If you want to do what you want to do, you have to do what you have to do.

I would think it has to be a switch that is normally open
and is now permanently closed.

pull the b/u light fuse in the fuse box so you can find out if there is a short before or after the fuse box.
