Ok, so when I turn on my high beams, my driver side low turns off. Not a problem with seeing, but stupid little things like that drive me nuts. I looked at the wiring diagrams, but am mostly confused. So what I am asking is, anyone have a likely cause for this problem? Thanks in advance, as always, your help is appreciated:clap: .

I'll guess we are talking about a quad light car?

 

Check the low beam filament in the one that does not

stay on.

 

Swap it with the other low beam and see if the problem follows the lamp.

If, it is a quad light system, your DS high beam is burned out, or there is a wiring/connection issue. As Skip said, swap bulb side-side to see if it follows bulb or stays with that side. A volt meter would be a nice thing to have really. One could check for proper voltage at connection and for continuity of the lamp filaments.

It is indeed a quad headlight car. I went out to try to remove it, and just stripped the screw, so I will wait 'til I can get into the shop and use the impact screwdriver. But I did notice that there is condensation in the driver side low beam, could that indicate anything? Thanks again!

I may be making stuff up here, but if it's like the quad system on my mitsubishi truck, you don't have low-beam only lights. You have two headlights that are hi/lo beam, and two that are high beam only. So, it's actually the hi beam portion of your lo/hi headlight that's burned out. This baffled me for a while when it went out on my truck till I figured out it wasn't a low-beam only light.

I had similar problem turned out to be a relay behind the dash low on drivers side, cylindrical metal can with plug on bottom. there are 4or 5 of them just swap one at a time to find hibeam relays
