Default Rear Defroster/Power Lock Gremlins?

Greetings!

Every time I try to turn on the Rear Window Defroster, the indicator light stays on for only a few seconds, then shuts off & I can't turn on the defroster at all.
Also, after trying to turn on the defroster [& getting the above results], the power door locks don't work....
[If I had not tried to turn on the Defroster, the locks would work]
Come to think of it, the power door locks will work fine when I first get into the car after it'* sat for a while, but by the time I get to my destination, they don't work...then after the car has sat for a while, they work again... :?
The fuses look fine, but I'm going to replace the Circuit Breaker anyway to see if that could be the problem...Any other suggestions?

Thanks!

Let'* start by cleaning the ground buses & see if that helps. Here'* a link to the TechInfo article.

If they are on the same breaker and it sounds like they are....

The problem could be your defroster. I have the same problem with mine. I haven't tried the locks yet, but if I use the rear defrost, after a minute or so, the breaker trips out and then I can't move my seats untill the breaker cools off and resets itself.

I am not %100 sure, but I think that it might be from only a couple of the defroster "lines" in the back window working. Some of mine are broken and only a couple of them work. I believe that only haveing a couple lines working acts like a short, drawing more current then the breaker can handle.

Like I said, I am not %100 sure on that, but that is what I figure my problem is.

Well, I did clean off both of the Ground Busses, but as I was finishing, my Buddy came over to borrow the car for a week [while his is in the collision shop after hitting a deer ], so I didn't get a chance to try the defroster to see if cleaning the Ground Busses did it..
But all of the defroster 'lines' / elements are in perfect shape: no breaks/gaps.. :?
So we'll have to wait a week to see if that took care of it before I try anything else...
But since he took the car, another [worse] Electrical issue has cropped up so I've started another thread
