Help Me Plz, Avalon Problems Fuse & Window

[Hostage]

Okay I have to seperate problems. I own a 96 Avalon.

Prob #1: Back right window will not open, neither the master controls switch or the passenger switch can open the window.

Prob #2:

Okay I was driving yesterday and my A/C, Clock, and Radio went out. I checked the fuse and my 15v blew. I replaced it later that night and the next day while driving it went out again. It occured about 30 minutes after driving. I called the dealership and they said it would cost 80 bucks to diagonse the problem. I am thinking about keeping the radio off and putting a new fuse and see if it holds. If it does, I am hoping it is a problem with the radio. I don't know what is causing the short and I hope someone could help me solve this. I've done no customizations to anything to my car. I have been driving a lot in the past 3 weeks, about 1,200 miles.

LMK and thank you,

Doron
