Hi I'm having trouble with my headlights and some side markers lights. I'm thinking I have a bad switch on the floor there is 3 wires that are going to it green blue brown the blue has power but the others don't even by pushing the switch. Is this the way it's supposed to be. I also don't have flashers working or signals but I think this is a different issue. :crying:

Dimmer switches go bad. I would not waste any time and purchase a new dimmer switch, rather than test wires at this time. IF the dimmer switch does not cure the problem, then you will have to get into wiring work - which can be a real pain.

Again, on the flashers, get a new flasher unit and replace the old one. These too wear out. They unplug and plug in, real simple. Make sure all your fuses are good. Go for the simple before looking for something major. :thumbsup:

Thanks Pontiacjim. I know rats chewed up my wire harness in the engine compartment I splice them together before soldering them to make sure everything worked then I hit the dimmer switch and lights went out so I'll be installing the new switch tomorrow will see if things light up?

That would be a headlight problem, and not the dimmer switch if they are now working. Most likely it is a ground issue, or wire grounding out on the body if rats have been doing some chewing - unless your lights have been replaced at some point with the brighter type headlights offered today and the one that is dimmer is of the older style - regular brightness.

You night just want to pull off the connector from the head light and make sure no corrosion has gotten in there either. Then check your wires for any exposed wiring that the rats may have gotten at and clean up the grounds - which you should find once you follow the wires.

Yeah its going to be something like a loose connection i wiggled wires from the drivers headlight and it got brighter so I think it's a ground that's loose or maybe like you said corrosion built up. By the way do you know the type of bulb that goes in the rear side markers

"By the way do you know the type of bulb that goes in the rear side markers "

Hmmm..... off the top of my head, I'm thinking a good one? :smilielol5: My '68 wiring book says #1895 or #194 for '69. The '68 is listed as #1893 or #194 . Not sure the physical differnces,but that should help.
