Dude, my truck has that same problem. The right side low beam is dim while the left side is bright like it should be. I have an additional problem of the high beam for that side staying on after I switch back to low beam. I have to turn off the headlights and turn them back on to get that high beam to shut off. I replaced the switch in the dash on a whim, but after looking at a wiring diagram I realized that couldn't be the problem. Now it's down to chasing a short in the wiring, a job which I'm not looking forward to. I have a Sport with the quad headlights, btw.

Best of luck fixing it. I'll post back if I figure out the problem with my truck.

 

the dim light could be solved by using a relay harness, the switches tend to cause a major draw of power from the lights, typically bad grounding, since its ground switched its a bit of a snaffu.

 

Hey Dracozny, can you tell me a bit more about the relay harness? I'm not sure what that is. Thanks for the reply.

 

relay harness just uses the stock wiring as a trigger to a relay which feeds power directly from the battery to the headlight, that reduces the load on the switch and gives the lights more power. newer harnesses can be found that do not use relays. should be able to find those for about $30+sh

 

I had the same problem as OP, used the relay harness and it worked like a champ.

 

esmith...before you do all this stuff check the fuses under hood over drivers side wheel...i rewired light...spent lots of cash at a garage...thought i checked everthing....then found a blown .25 cent fuse...i see dim lights everywhere !!!
