Thank you for going the extra mile with diagrams. Unfortunately, were are not able to find a fuse marked #3 nor any fuse that seems to be related to the defroster.

Thank you for your time.

Can you take a picture of your fuse box so we can see which configuration we are dealing with. Please use your phone and upload here to the site so we can see what's going on.

Cheers, Ken

Wanted to let u know we gve up trying to figure out the fuses and took to the shop. $45 to replace fuse. He said he used a testerto find fuse as Jeep is not very user friendly on fuse diagram. Thank you for your time.
