1999 Volkswagen Passat Q&A
1999 Volkswagen Passat Question: Maybe a fuse has blown?
Checking your fuses is an excellent place to start. If you find a fuse blown, determine what is on that circuit and disconnect on thing at a time until the fuse stops blowing. Try the heater motor and wiper motor especially. Make sure there isn't a bunch of leaves and debris up by the windshield, this will cause water to contaminate the electrical system, possibly causing your problem. - Bret Bodas
The electrical portion of the ignition switch could be failing. Not at all uncommon....... - spyder
