headlight troubles GRRRRRRRRR

Ok so on my way home tonight, I flipped on the headlights and it looked like I had one out. No big deal as I had some new bulbs at home. I noticed before I changed the bulbs that one was fine (drivers side) but the passenger side bulb was really really dim. getting power but not putting out much light at all. I tried moving the harness around a little to see if it was possibly a bad ground or something but got nothing.

I swapped out the bulbs with new ones, same thing. Checked the fuses, all is well. One light is fine, the other is dim. The harness doesn't look damaged or anything. I had plans to go out this weekend on a trip and would like to have some lights lol

Anyone have any ideas that might help? I'm lost on this one.

Get a voltmeter and start by checking the good headlight. Then start on the bad side, at the bulb connector. Trace it back until you match the voltage in your good headlight and find the fault. Could be a wire rubbed through or something corroded or unplugged halfway. Good luck!

The Voltmeter's a good idea....i need to get a new one anyways, this sounds like a good excuse to do it lol.

wouldnt a wire rubbing through cause the light to go completely out?

Does sound like a ground problem.

G105 may be corroded.
Its on the PS inner fender (under the hood), just forward of the blower motor.

You may have to remove the cruise servo (one bolt) to get to it.

a ground issue does seem to be the overall opinion. i traced the harness back and found the ground on the fender. it looked fine but i pulled it off and cleaned it up anyways. maybe ill try running it to a different location just for fun and see what i get.

Shane, the light that is dim is like.....REALLY dim lol. I'm at work now......not working lol, but I'm going to get a meter and try a new fround and see. I'm really not sure what else to try. A friend of mine is a mechanic and is really good with troubleshooting wiring issues so I'm going to bounce it off him too and see what he thinks.

The only problem I have with taking it to a dealer is they'll probably throw parts at it until its fixed leaving me with a $300 bill for something that was probably a $10 part lol

I have had exactly this issue when my truck was new. I didn't feel like waiting at the dealership so I pulled the right bulb out and found the ground wire in the connector spread open so far that it melted the plastic a little bit. I was able to take a pick and close it up and all was well. It actually got so weird once when I hit my brakes the fog lights would turn off.

I figured it out. Thanks for all the help guys.

When I took the bulbs outlast night, I noticed I was running 80w by 100w bulbs. I dont recall putting bulbs with that high of a rating in there but oh well. The bulbs I have in now are the stock wattage and were giving me the same problem. I unplugged the bulb when I got home from work to run some tests with the multimeter and when I was pulling out the bulb, it got bright.....

In a nutshell, the plug itself was pretty much fried. I was able to clean it up and filled both plugs with some di-electric grease and they're working fine now, but I need to swing by AutoZone and get a new plug harness and splice it in.
