i just picked up a pair of TYC taillights for my 09 tC. I installed them and the left taillight works great, but the right taillight does not light up any LEDS. the turn signal and reverse light both work.
They are all powered by the same connector, so i'm thinking the LED's are shot?
I have already tried replacing the 10 amp fuse for the taillights, still no luck.
both the running lights and brake lights(everything that involves the LEDS) do not work.

any other ideas as to what i can check will be greatly appreciated

 

There's a small connector on the harness, plugs on to the pc board inside the light. Sounds like that may be disconnected.
It's under the small rubber 'flap', under the big rubber gasket / seal.
You can see the connector on the harness in the pic. Check that.

 

thanks alot, that's exactly what i was looking for. its most likely the cause. ill check into it!
