I understand that our light switches can be the culprit for intermittent non op headlights (my truck is an '83) Is it a matter of reflowing the solder or other. Are new switches still available or other? Thanks!

 

i would be looking at the dimmer switch on the floor. most common cause of headlights not working.

 

Yep, there is no "click" function (detent broken) with high low switch and one mount broken on floor switch - time for a new one, will test in the am-thanks

 

Yep, pulled floor switch, oem, plug a little burnt and melted slightly, picked up a new switch at Napa and also a 3 prong plug and wired in - all good now, thanks Wolfie!

 

no problem. like i said it is a common issue because of the location. i sometimes try to fill them up with lithium grease to help keep moisture. i also keep a couple on hand just in case since they are cheap. it may also be worth installing a headlight relay harness under the hood to take some stress of the dimmer switch connector. it can also in some case make a noticable difference to the light output of the headlights.
