When you turn the switch off the taillights come on, sometimes it is both and sometimes just one. I have checked all of the fuses and the brake sensor, but it is not the brake lights. The taillights and the blinkers will blink fast sometimes and work normal. I replaced all the bulbs. If anyone could give me some advice I would greatly appreciate it. Oh yeah, I checked for bad grounds as well and I just do not know. I am clueless.

Hey JOSHUA3585,

I would check all of the bulb sockets in the front and the rear to see if you have any terminals inside that have melted together. If they seem okay its sounds like the multi function switch is having a problem. Check it out and get back to us.
