NEED the interior light just above the rear view mirror....

I have 2005 roadster and for some reason the left side lamp will not work for love nor money. I've taken the thing apart - cleaned up the contact point - elevated the power strips - replaced the light bulbs...I've done everything I could think of to get the dog gone thing to work. I'll get it working for a day or two then the left light goes back out. I about tossed the entire light assembly in the trash can the other day I was so frustrated with it. I'm done playing with the darn thing. I'm looking to replace the entire assembly and I've check Ebay and several other sources. I haven't scavenged the local junk yards though. That would be the next logical step. Anyone have one for sale ? It's an ODD item I know. This cabin light just been on my nerves something UNREAL. It's one of those unimportant things that just bug the CRAP out of you...
