Here's an issue. No lights. Found a relay next to the battery and it powers the high beams only but I'm not getting the power to reach the low beams. When the switch is turned on a clicking noise is heard under the dash but only the park lights come on. I know with the number of times the instrument panel has been removed, the circuit for the park lights on the panel is damaged and doesn't come on but the external lights do. Help!!!!!!!

the low beams is controlled from a relay by the fuse box in mine one side of the switch is high the other is low, I just jumped it out as the relay was always sticking to high beams. that's where I'd start with the ole spark chaser. (my book is in my truck at the windshield place so I'm not sure until I get the prints back if yours is wired the same as mine. I think the wiring changed after 83. tomorrow if you haven't got it sorted I'll give you a step by step to finding where the voltage is going.

But prolly relay. or your switch in the column.

When I noticed the no light issue, I serviced the switch. She already had work done on the light system, so when it stops raining cats and dogs I'll check it out again.

Check the light switch itself. The contacts on the switch get corroded over time and don't make the right "contact" anymore. Rubbing alcohol and an emery cloth will work.

Easy to check and fix!

sorry finterman expected to get back to you before now, the windshield installer guy busted the replacement windshield trying to put it in urgh. I forgot to grab my book out of the truck while I was there. Now I have to wait on a new friggin windshield. I feel like I'm about to start my period lol.

well I have some strange happenings on my light circuit as well. It seems like if anything goes to ground it triggers the high beams panel indicator (could be one light out, relay switched but defective lights etc...) well I replaced my low beams and mind you I have the relay jumped out so there is no possible way the high beams can come on (either via the switch or relay) but occasionally I'll lose the pass side beam and the high beam indicator will come on. (now I jumped out the relay after replacing it, the contacts was still "sticking") well I reached down to the fuse box and felt the 2 fuses that run your beams (two 10 amp fuses first to positions closest to the engine bay) they were hot hot hot. I'm surprised they haven't blown. I think stock beams are supposed to only pull like 4.6amps per light on the low beam circuit, so I'm thinking something is intermittently going to ground.

which brings me back to your issue finterman. first off if you have power at the relay that is powering your high beams then you have power there to power your low beams (the relay just switches it), thoroughly inspect that relay base for lose female metal thingies in side the base and the wiring on the backside if everything looks kosher make a jumper and jump between the com and switch legs. (there should be a diagram on the relay or you can figure it out with a multimeter) you should get your low beams on one of the switch legs. if you do disco you found your problem if not let me know and I'll figure out some more things to try.

Sorry to take so long to reply. The day after this post it went back to the electrician, so I could not check anything. Will be going to see the electrician Wednesday. Info soon after.
