89 300E Door Locks keep blowing fuse
Yesterday I got into the car and the temperature registered at 115 F. The car started fine and then I noticed that the dome light remained on, and the seatbelt light kept flashing. Both remained on the entire trip. When I tried to lock the doors, the locks did not work. I replaced the 16 A red fuse this AM, the doors worked once, then blew the fuse again. What did I fry? Thanks in advance for your help.
