These will help.

Thanks.

If it is just the left side the bulb is probably blown. fuses will take out both sides

The rear light assemblies need to be removed and the replaced. The filaments have either melted together or the wrong ones installed at some point. Let me know if you need anything else.

I would check if they also run off of a relay, You could have a wire that is either broke or it is grounding out somewhere.

Signals are now controlled by a module on the right side of the steering column under the dash. Before doing anything yourself, bring it to the attention of the guys that did the rear...This problem can happen at any time but they may have disconnected a harness or ground while working, so give them a chance first to correct it.

you may need to replace the caliper

sounds like the bulb you have is the wrong resistance the new noen bulbs will do this

Check the relays associated with the tail lights, I believe that the tail light relay and the turn signal relay are two different entities. Hopefully that helps.
