fan switch

  1. VW Jetta MKIII 1991–1998
    '97 Jetta. When I have the fan switch position 1 and 2 the A/C works fine, compressor is on and blowing cold. When I turn the switch to position 3 or 4 the A/C turns off, compressor off and light on A/C button off. Thanks for any ideas or help on this. Bob
