Re: Clock. Rear wiper.
Hello! Welcome aboard! I'm afraid i'm still learning where fault diagnosis is concerned with Jeeps but they do both seem to be real head scratchers! I'm thinking p'raps the wiper fault may be with the switch or circuitry rather than the wiper/motor itself but i'm sure someone a lot more knowledgeable than me will be along shortly! Best wishes.
