When that switch went out on my '88 coupe, you'd turn the headlights on and the instrument cluster and taillights would not light up. Replaced the switch, problem solved. Its not uncommon for the switch to break.
Thanks Peter, - it was on the old forums but since they are becoming a ghost town I thought I'd take the opportunity to repost herePSA said:Laurent, didn't you have this whole procedure posted somewhere? I remembered it as the best procedure I'd ever seen, but couldn't remember where you had posted it.
