Left front Daytime Running Light /Turn signal
OK my Corvette Forum friends, again I come to you with a situation and request your assistance.
I have C5 2001 coupe. The left front running light and turn signal don't work. The left side parking light does work. The rear turn signal and brake lights work as they should. The right side lights all work as they should. I have already replaced the bulb with a new one (twice, two different blubs). I already replaced the #40 relay, even though I swapped the #38 and #40 and there was no difference in either one. I have read other posts where the running lights, 4 way Flashers and turn signals were inoperative... I think my situation is a little different than that. My situation only pertains to the left front Daytime running light/Turn signal Any and all suggestions will be greatly appreciated... |
when I turn on the 4way flashers, 3 of the four work. the left front does not. Where does this wire harness plug in the to main harness? I want to run back up the harness and check the connections.

A fried L/F bulb socket can be a problem too. They get cooked over time from all the heat from the OE incandescent bulb, which is the source of the C5 parking light/DRL issues in the first place.

Cannot be the fuse if the RF light works since the same fuse services both sides and if the relay #40 and the LF bulb are known good, there are only a few things that it could be.
Wiring between the relay and the bulb, the bulb socket itself, the ground (Splice pack 100 and G102 which are on the left side frame near the headlight) or a BCM problem since the BCM provides the ground for the coil side of relay 40. Is or has the carpet in the passenger foot well been wet?? No, never been wet If none of the above are found to be a problem it could be the portion of the multi function switch that operates the LF turn signal. Separate electrical power path in the MFS for LF, RF LR and RR signal lights. So, I found the plug under the Right Front headlight. I unplugged the harness and used my volt meter. I touched the black wire prong with the negative side of the meter. with the red probe I touched the Dark Blue wire prong (right side light) and got a 14 volt reading. When I touched the Light blue wire prong (left side light) there was no power... Therefore I'm leaning toward the Multifunction switch... What are your thoughts? Where can I get the correct GM part number for this? I looked on GM Parts.com but they only show the switch for NON Telescopic steering column. Mine is telescopic. |

Unfortunately I cannot help you with sourcing the MFS as I have NOT had to do that yet. I did just do a quick look on a couple of parts places (Rock Auto, O'reilly) and they do NOT seem to make note of the telescopic column. That is not conclusive in my mind so I might call a local dealer and ask if there are two different parts or not...... http://parts-catalog.acdelco.com/cat...log_search.php Click on "wipers/lamps/fuses" > then "Lighting Modules and Switches" I've changed one out before and not nearly as difficult as I expected. |
Just went through this.....no head lights-was twisty thing on stalk switch..
