99 passat wont start and windows wont work. i checked all the obvious fuses and relays. i had a blown fuse changed it and it started then a day or so later it did the same no start no windows i changed the ignition switch today and no change still no start or windows

SOURCE: starter enabler fuse blows which means the starter motor does not work until fuse is changed

It is possible that the starer is pulling too much amperage- 1st thing you need to do is find out what if any other consumers are on that circuit, 2nd you need to find out how much amperage is being consumed by the starter. 3rd test you wires most likely if a wire problem it is the heavy hot wire on the starter or the back of the alternator has a loose retaining nut

I had a prolem like this one time a while back. what i did was got the wiring diagram and checked everything that was running through that 30 amp fuse. on the one i was working on it ended up being an injector wire pinched under the valve cover and it didnt short out till the car was driven til it warmed up and expanded after the valve cover gasket was changed. hope this helps!

THIS ONE IS COMPLICATED ONE RELAY AND SO MANY PROBLEMS CAN CAUSE THIS PROBLEM
1) THE RELAY YOU ARE HAVING TROUBLE WITH ON THE FUSE BOX COVER THERE SHOULD BE A CHART OF WHAT FEEDS WHAT WHAT DOES THE LID SAY IT FEEDS
2) TRY PULLING THE FUSE TO THE SUN ROOF AND DOOR LOCKS AND REPLACE THE RELAY IF IT STAYS IN YOU HAVE A PROBLEM WITH ONE OR THE OTHER. THIS COULD BET A MOTOR PROBLEM ON THE SUN ROOF OR A DOOR LATCH PROBLEM.

IF THIS DOS'NT WORK I'LL HELP YOU THE BEST I CAN WITH OUT SEEING THE CAR. THIS IS ONE OF THOSE PROCESS OF ELIMINATION REPAIRS AND TO TAKE IT TO A REPAIR SHOP THIS IS GOING TO BE EXSPENSIVE

SOURCE: 2002 GMC Envoy, i put the key in ignition and

Ignition switch and neutral safety switch. Next time it happens wiggle thekeys in the ignition switch and try to restart.If it starts its probably the ignition switch. Then locate neutral safety switch on brake pedal and put meter on B+ wire from switch to starter relay and see if you get B+ on the would -be- crank. Next locate B+ wire from starter relay to starter hook a meter to it and see if you get B+ on the would -be crank.
Where ever B+ is missing is your problem.
