I HAVE 1996 JEEP GRAND CHEROKEE ,THE INTERIOR LIGHTS ARE COMING ON AND OFF AND THE DOOR LOCKS ARE CONSTANTLY LOCKING AND UNLOCKING AS i AM GOING DOWN THE HIGHWAY. i REPLACED ALL FOUR DOOR SWITCHES, THINKING i MIGHT HAVE A BAD SWITCH THAT WAS CAUSING THE PROBLEM. ANY IDEAS???????????
THANKS

I would look at the wiring harness that routes through the door from the main body of the jeep. Good chance you have a wire frayed or broken that is making intermittent contact, causing your lights and locks to operate.
