Turn signals..imagine that. Left side marker will not flash sometimes and if I plug in the NEW bulb I can see that it is only burning at a minimum where you couldn't tell it was on unless you were looking for it (but not flashing). My hazards work fine..except my front left turn signal indicator does NOT work (it work when flashers are not on). I can see a faint left turn signal indicator light on my dash lit up. Also, I don't believe this is related, but who knows?? I have had my interior lights stay on while driving. The only way I can seem to get them off is to lock the car with my remote.

If you don't have a multi-meter, get one. Check the bulb socket for corrosion or grounding. Also, chase down the wire loom for the socket and looked for frayed wires, worn insulation, etc.

cleaned the connector, checked the wires and shook them too, nothing changed. It will work with flashers, but not my turn signal. Flasher is working. Is there any possible way it could be in the multi function switch? Any other switch it could be?

I would check the multi-function switch. They can get debris in them as well as just plain give up and break.

Is there a way to check if the multi switch is bad other than replacing it?

Please add your year and trim of your vehicle to your signature line. That way when you start asking questions in other areas of the forum, we all have a better idea on how to assist you. Click on "Quick Links" above, go down to "User Control Panel" and then click on "Edit your Signature" It'* pretty straight forward from there.

For a 1988 and later model looks like for the LH side you want to check for voltage on the Lt. Blue for front and the Yellow for tail. The RH is Dk Green for Tail and Dk Blue for front. These wires will be coming from the Trun/Hazrd Switch Assembly.

Thanks, you have been a great help. I will be continuing to look into it tomorrow.

Call me a redneck...but I don't know if I have the time to take the entire steering column apart. Has anyone every tried to cut the wires, pull them through and them reattach them after the column or is there something else in the column that I have to mess with. (I already have the multi switch unscrewed)

Something that has me perplexed. I looked at the switch which is VERY simple. I took it apart cleaned the contacts and greased them again and reassembled, but I am still having the same problem. Right side works...not the left, but the contacts look exactly the same...in great condition. Could there be something else? Wires look good as well.

It seems as if I found the problem. After all the testing and wiring and whatever... it appears as if the contacts in the other bulb were the problem. Cleaned the contacts and everything seems to be working fine. Thanks for all the help.
