Hi
I own a 2000 Jeep Grand Cherokee Laredo and the break lights don’t work. Checked fuses they are ok. Any suggestions would be great.
First thing Id check is the switch at the base of the brake pedal. It could be broken, or simply out of adjustment.
Also check on the ground wire.
Along with checking the brake switch make sure you are getting power to the switch. Use a test light to check that. If the switch is ok and power is good then check the connections in the rear for a problem.
