63- headlights won't work

[jonzcustomshop]

After a brutal week of changing auto transmissions on the 63 3 times (the one constant was a "good" converter that I didn't know was bad), now the headlights wont work-- they did when I parked it 6 years ago with the bad trans.....
the running lights in the hood, dash lights, and taillights all turn on, just not the headlights--they are still plugged in at the core support---

What should I check, or look for??

Dimmer switch would be my first guess. I thought my switch went out, so I bought a new one, but that didn't fix it. Then I remembered that I had disconnected the plug at the core support for some reason and forgot to hook them back up Anyways, I left the new switch in, and about a year and a half later, that new switch went bad. Replaced it with the one I first took out, and that switch has been great ever since

Times 2 on the dimmer switch. Usually it just the connections as they are prone to corrosion due to their location especially if the cab or windshield leaks.They have pigtails available

I agree on checking the dimmer switch.

Thanks guys! Yep dimmer was triggered- bright is no light, and dim the lights come on! Don't know why I didn't think of that.... A little off my game! Haha...

Will have to check out the connections in the daylight.

The contacts on the dimmer get dirty so it doesn't work. Cycle the switch about 10-20 times and it should start to work.
