Multiple Alternator Failures on 2003 Jetta GL 2.0 by jayint32

I have a 2003 Jetta GL 2.0. It has about 108K miles on it. Recently while driving electrical power gradually drained until indicator lights came on as systems shutdown until finally the car rolled to a stop. I brought it to the mechanic who said I needed a new alternator. He installed a rebuilt alternator. That worked fine for about 120 miles of driving over the course of about two days. Then the same exact thing happened. All electrical systems shutdown and the car wouldn't start. The battery was drained. So, I assumed I got a bad rebuild. I brought it back for a new rebuild, this time from a different manufacturer (same re-builder though). About 100 miles and two days later, the same exact thing. This has cost me about $1000 in repairs, tows and hotel bills. Either I've coincidentally received two bad rebuilds in a row or there is something else going on. Has anybody else had this type of problem? Any suggestions on how to troubleshoot it?
 
Thanks!

So, after my mechanic checked the car out, he found that the alternator is still good, but the 150 amp fuse in the fuse box mounted on top of the battery melted. He replaced the fuse and the car is working now. It is still unclear what the root cause was though of the original alternator failure. It may have been the old battery. I installed a new battery now and plan to drive the car this weekend to see if anything happens.

Clock/Odometer Won't Shut Off After Removing Key by michaelter

Hi. I replaced the battery in a 2005 VW Jetta this weekend. I had the battery disconnected overnight, then put the new one in and the car works fine. Now, when I take the key out of the ignition, the clock/odometer stays on, and the battery is slowly dying overnight again. I drove around for about 70 miles or so to reset the drive cycle but it's still staying on. What do I need to do?

Power Window Gremlins by alf944

Having power window problems on 97 Jetta. The only way to get the windows to go up is by putting key in passenger door and turning key. Only problem is about 10 minutes or so the windows go back down on their own with one one near the car. If you go inside the car after using the passenger side door lock to put the windows up then the only way the windows go up and down using the window switch on the door is if the car engine is not running. After this the windows still go down on their own after you leave the car. Tried to find the power window fuse to pull it when the windows are temporarily up but can't locate the fuse. Rain coming tomorrow...Not a good thing.

steering wheel lock...weird??? by dan191

I just bought a 1996 vw jetta. I bought just a few days agao and it has been sitting for around a year and the battery was dead and the steering was locked and wouldnt unlock, i was told to put a new battery in it and it would unlock for me....so i did and it didnt work.
 
When i hook the battery cable up the alarm goes off for a while and the steering wheel wont unlock for nothing. I have jerked on the steering wheel pretty hard while trying to turn the key over...its stuck.
 
Is this an alarm issue? the guy i bought it from said he just parked it last year and hasnt ever had it do that to him.

Not that it does any good now, but when you were told "put a new battery in it and it would unlock", the correct response was "no, you do that before I buy".

Ah, I see, only $250, that's only a little more than the scrap value, then. Does the key turn? If it does it must be the correct key, right?
 
I wouldn't think it is an alarm issue. I don't think that would result in the steering wheel not unlocking, I could be wrong, though.

Dan Give this a try. Observe which way the tires are facing. If they are turned left or right, give steering wheel a hugh FORCEFUL TUG towards the way the tires are turned and hold the steering in that position while attempting to turn key. Hopefully this will work. Goodluck

What gets me is the car ran fine in the morning but when I went to drive it in the afternoon it would not crank You turn the key on and the ASL light comes on then immediately goes off and a relay clicks in the gear shift console. The gear indicator on the instrument cluster starts to flicker on and off and when I turn the key to start it ... absolutely nothing happens. battery also drains and gets hot after a few tries...plz help
