I have a 1991 PA that does not have lowbeams. It is electronically sound in all respect except that the lowbeams cut-out around Feb-04 and never came back on. Highbeams work great and the "light monitor display" shows that the lowbeams are burnt out. I checked fuses, wiring, and yes I did replace the headlamps- no luck. Is there a module or a relay that typically burns out?? Thanks, Dave
