I have a 2001 VW jetta 1.8T and the chime doesn't work at all. if you leave the lights on, key in ignition. and it doesn't seem to register when the 2 front doors open; only the rear doors and trunk. could the 2 front doors have something to do with it? or is there a fuse? I also hear it could be a door switch? anyway if I could get this problem solved I'd be really happy. thanks
