Hey guys.. Here's a good one for ya'll to ponder.. About 3 nights ago I turned on my headlights to head home when I realize that only one came on (the right one). So when I got home, I thought I'd try the high beams. Low and behold, the left lowbeamer came on. So I figured half the light bit the dust and replaced them all. I get everything installed (no easy feat either) and hit the lights. WTF? Same problem!! [img]images/icons/frown.gif" border="0[/img] When just the low beams are on, only the right light comes on, but when I hit the highbeam switch, they all come on. Any ideas anyone?? I'm kinda stumped since all the wiring passes thru the left light first, right?<P>Thanks guys!

When you turn on the high beams, is the high beam or low beam filament lighting in the bad outer unit? If it's the (correct) high beam that's lighting and the low beam isn't functioning, It's either a broken connection to the hot contact or a bad ground for the low beam.<P>If the low beam is lighting when the high beam's are on, you may have the plug wired incorrectly, with the connectors switched. <P>Either way you should be able to check for juice with a volt meter and figure out what's going on. Compare results to the correctly working light and see what you get.<BR>Use the ohms scale to check for conductivity on the ground circut, there should be negligable resistance. <P>Good luck!

Thanks Dave!<P>I went out and tried to find what you were speaking of but failed. So I did what a stressed out person did.. Pulled the wires out again. heh-heh.. I sprayed the dickens out of it with electrical cleaner and pluged it back up. Well, ain't that a monkeys uncle.. It works! So now I have 4 good T3's sittin in the garage. I am currious as to why it just decieded to quit that night. Since I'm talking about lights here, might I ask where the ground wires are for the tail-lights? I need to clean up some gremlins that be stealing juice at stoplights.<P>Again, Thanks Dave!

Taillights usually ground to the body thru the pod. Look at those miserable GM sockets and you'll see a prong that contacts the pod when you twist the socket into place. Sometimes it's bent, sometimes corroded. Clean it good and set it so it makes good contact with the light pod and then scuff the socket opening on the pod to clean off corrosion. <P>And then sometimes replacement is the only option. Didja know GM used three different taillight sockets those years? and even though they'll all plug in the same, the focal length is different- meaning if you use the wrong one, the bulb won't be in the right place with respect to the reflector, and the lamp will be either too dim or too bright.
