Rear light issue

I've searched and searched, and can't find a similar problem. Good news is I know what caused it...I did.

I was bending the tabs out on the driver side rear driving/brake light to get a better connection with the bulb, and I forgot to turn off the light. Therefore, I shorted it out. Now neither the driver side brake or driving light works, but the passenger side works. I swapped the bulbs = good, I even swapped the bulb bracket, and still same result, the bracket is fine, driver side doesn't work. Fuse 22, and 41 is good. So the bracket, bulb, and fuse is good.

I'm afraid this only leaves the light switch module. Any suggestions on how to test this or what else it could be?

The fuses you checked are for the turn signals etc., not the brake light.

Have you checked the fuses in the N7-1 light control module fuse block?

You sir, are my hero. All my searches, and this fuse box never came up. Only had the car a month, so still learning. That was it, blown fuse.

So, that got me back to where I was. Unable to get the contacts to put enough pressure on the bulb to hold it consistently, so I'll be replacing the bracket.

Thanks again Serndipity, If you are ever in Tallahassee, FL...PM me, I owe you a bar tab!
