No Lowbeam Headlights?????

I have a 97' PA.When I go to dim the lights,there are no lights.It works fine on high beams.I have checked all the fuses I can find related to the headlights.I am totally lost.PLEASE HELP:banghead:

Sorry no one timely replied. First make sure the low beam lamps are not burnt out. If the lamps are good then check the 12 volts at the lamp socket and make sure the ground is good. Common problem for a lack of low or high beams is the multifunction switch (MFS - Stalk).

Where would that be located? I just replaced a bulb awhile back and they were working fine.It just stopped one night and the next night it worked for a liitle bit the stopped all together.
