Having problems with your 2002 Jeep Grand Cherokee ?
High mount and right rear brake light out. high mount is blown but the other 3 are fine. Can the high mount prevent the other brake light from functioning?
Nope, high mount comes directly from the brake switch, the other two come from the brake switch to the turn signal switch then to the back, seen a couple of the circuit boards bad in the tail lamps, if one side is working good try plugging the good side into the other side and see if it still works, if so its the tail light.. P.S. if vehicle has trailer wiring double check that too, usually that's a huge issue...
