Chrysler Repair: 2005 Dodge Minivan: radio fuse keep blowing, dodge minivan, sorry fot


Question
I'm at my wits end with this one. Dealership not being very helpful. Here is the problem.
The radio/cd player suddenly stopped working. The lights light up, you can load and unload cd's, but radio does not turn on. Went to dealer they said needed a new unit. Unit was replaced went to pick up, it still didn't work. Tech checked fuses found a blown one changed it system worked for a few days. Now system comes on and goes off whenevr it wants. When it does not work can still load and unload CD's but nothing plays and radio does not work. Changing the fuse works for a few hours but than same thing happens again.
Just got it back from shop, who told me they replaced the fuse, than ran the car for two hours and system still works. When I picked it up it did work, but this morning when I started the car, radio is now out again. Any ideas?
Here is a little back ground information also, when I bought the car, dealer installed a Remote Start Unit. It worked well for two years than system would start than shut off immediatlty. Dealer replaced a part (? Skrim ?) twice but problem was never resolved. I was tired of this issue, so I asked for my money back on the unit. They gave me a credit to use in the future. As far as I know the system is still in the car and I think this is related to the current problem, but nobody at the dealership wants to listen to this.

Answer
Hi Tom,
I suspect that there is a short in the wire that the fuse serves on its way to the radio, probably a break in its insulation that is causing to touch another wire or a piece of the body structure. The remote start unit could be involved if it was wired into this same fuse or its wiring in entangled with the wires for the radio. My latest van manual is for '02 so I can't be sure I have the details applicable to your '05 but if you would tell me which fuse is blowing and its amp rating I can see if this agrees with what I show for the radio supply.
