Sort of a renew post I cannot find the relay for my 1999 suburban 2 rear door window defrost relay. It is not located in the relay/fuse box located in the engine compartment although there is a 30 amp fuse labeled rear window defrost, and no relay under dash by parking brake box. any help on this would be appreciate. by the way the dash controller was just replaced and I get a light on for the rear window push button as well as timer works, grid in windows shows good continuity with ohm meter just no power to contacts in door frame.
