Hey guys, so i have a 1997 cherokee country edition w/heated mirrors and defrost and basically everything but leather. however my defrost for the mirrors and rear window will not work. any ideas on the best place to start looking for where my short could be coming from? just for a history i replaced the rear wiper switch last week and noticed the defrost switch wasn't pluged in. so i plugged it in and tested it. it powered up and then turned off. when i went to start it later it wouldnt start as it blew the 30A fuse which is for both the rear defrost and starter.
