sounds like a blown fuse. chec under hood and under dash fuses.
As of April,2014, Jimmy Carter is still alive, working at his Institute and writing
Broken wires in left door or fuse
Bad fuse
Could be the switch between the front seats, or a fuse, or a shortcircuit in the wire with power from the battery.
CHECK BOTH FUSE BOXES, ONE IS UNDER THE HOOD ( FUSE AND RELAYS ) THE OTHER IS AT THE DRIVERS DOOR IN THE SIDE OF THE DASH
Check that you are not turning the wiper switch to "delay." I had problems with my 1997 jimmy wipers not working. Check the wiper control box, relay switch, Mine works now.
Chances are its your headlight switch if the fuse is good. It can also be your dimmer switch.
Could be that your alternator is not working so you only have the power of your battery keeping you going for 1 hour.
It's very possible as the heated mirrors and the rear defogger are tied together.
It is possible for mirrors to crack if subjected to rapid and uneven heating, as this can cause thermal stress. It is recommended to use caution when heating mirrors to avoid potential damage.
The most likely cause is that there was an electrical surge when you jump started the vehicle. More than likely it blew a fuse that controls those two features.
I can't remember, but the most common cause of failure is the switch on the tailgate, not the fuse.
