09 reverse lights stay on

I just bought a new 09 GTCS.

2 weeks ago (739 miles on it) I ran over something on the interstate at night and cut a tire. It also knocked the rear bumper cover loose on the drivers side.

I got a new tire and reattached the bumper cover. It has minor damage but not much. (still hurts though!)

Now I notice the reverse lights stay on almost all the time. When they are on (and not supposed to be), the cruise control doesnt work. When they do go out while driving, the cruise works fine.

I took the back panel in the trunk out to check for loose wires. Nothing made the lights go out. I shook and knocked around under the car but the lights stayed on.

Any ideas???

Thanks!

+1 on the sticking reverse light switch. I believe the reverse light circuit disengages cruise so it can not engage when in reverse.

Well... 2 things you should do...

1.
I'd recommend basically reseting the electric system... With the car off, take apart the trunk again (I've done it around 10 times trying to get my sequentials working... I know, its a pain ) and disconnect the tail lights from the main harness. Plug them back in, then turn the car on. That's what I'd try first. If that doesn't work, then disconnect the battery and leave it disconnect for over 30 minutes. Plug it back in, start her up, then see if the problems still there. If it is... See #2! I'd try the first part again after reseting the battery before going to step #2 though.

2.
Go to FORD! They have the knowledge to easily fix the problem, and with your car being an '09, you have full warranty! But only go there after trying #1.

Good luck!
