Hello Everyone, I need help for my cruise that quit working. this happened sometime after installing new LED taillights. Don't know if this would have caused the problem or not. Anyone had this problem?

 

Welcome to the Tahoe forum. It'd be a pain but you could put the OEM lites back in to see if the LEDs are the problem.

 

I know its simple and maybe obvious but as shawnvw said in another post...did you check the fuse?

 

Problem is probaly to do with the LED's. The cruise module needs to use the filament in the bulbs as a path to ground for it to work. You could use a relay to open the light blue wire at the cruise module. Have the cruise side of the wire go to ground through the relay, then the car side of the blue wire to activate the relay and lift the ground.
