Subject: No high beams on 1987 9000


The high beams don't work on my 1987 9000T and I can't pass inspection without them working (they haven't worked in about 5 years, but new mechanic at the inspection station). Low beams work OK but when I use the stalk switch for either flashing or turning the high beams on, neither the highs nor the lows come on. Dashboard high beam indicator went out about a year ago, but seemed to work even though the high beams didn't). I checked the bulbs - OK (put them in another car and high and low beams worked fine); fuses (one each for left and right), OK; I pulled the relay panel from behind the glovebox, noted that the horn relay and the "headlamp" relay had the same #'s (4 prong relay), swapped the relays, horn blows OK but still no high beams. My conclusion is that it's the switch, on the steering column which controls the high beams, turn signal, hazard lights, and cruise control. Turn signal and hazard functions are OK, cruise doesn't work (hasn't worked in a while either, but there are too many components to conclude that it's the switch). From my reading of the factory wiring diagram, there are no other components in the high beam circuit path. I understand some later cars may have a "big relay" which controls this which often goes bad. The biggest "relay" in my panel is a "filament monitor" which checks (I thinks) that all the bulbs are working. In checking part numbers, 1986, 1987, and 1988 each used a different part # for the switch. The switch is $250 min from a dealer -- anything I've overlooked before plunking down the cash? Suggestions/help/sympathy greatly appreciated -- thanks in advance. Alan
