Stop by AutoZone or Advance Auto Parts, they have free service to check the battery. It looks like with wipers you have a separate problem. You are right it might be wiring, but it might not. Most likely you just haveoxidized wires, so you need to check that. Also the mechanism which is responsible for wires can be damaged, ware off or just rusty.

No it is an internal battery and the manufacturer, although realizing that the battery life seems to be an issue, has not offered a fix for the problem.
There is no problem it is when you put anti-freeze in the washer bottle that you have a problem.
my best simple guess would be that there is a problem with your battery.... if you can, try another battery and see if that fixes the problem... if not, the problem may lie in your electrical re-charging system, like your alternator or wiring... but, before you replace the battery, clean the battery terminals and terminal connections.
No idea but I have the same problem with mine !
If your 1997 Passat dies sometimes, you might have an issue with the alternator not charging the battery. You could also have a problem with the distributor or the coil.
I know that sometimes sat nav has a problem in a 206 due to the athermic windscreen that can block some of the siggnals on gps. Check with car hand book to see if this is the case for your car. Not sure what you can do to fix problem though, check with manufacturer
I have just came up on this same problem with my 2000 Kia. Turns out it was the Ignition switch. $160.00 to have it replaced.
Have you removed the battery cables and cleaned the battery posts and cable connections? This is a frequent cause for the problem that you describe.
I had the same problem in an old Chevrolet, and it turned out to be a short in the battery. Check it out.
Its probably just out of battery and it also takes ages to load up sometimes.
I've never had any particular problem with it, although the crudely made magazines have proven to be an issue sometimes.
