Paul,
Thanks so much. The instructions were very well written. After I understood that I had to pull pretty hard and wiggle the headlight knob, it came right out.
However, I was disappointed to find that changing out the headlight switch didn't fix my issue of pulsing headlights/pulsing dash lights.
Since I'd recently put in a new alternator and a new voltage regulator, there were only two more thing left that it could be...the condensor for the alternator (mounted with the voltage regulator) or a bad ground somewhere. I was hoping that a new condensor (FYI- Kragen Auto Parts calls it a capacitor) would solve the problem...it DID!!!.
The thought of hunting for a bad ground just seemed daunting.
Thanks again Paul.
