Stop light not working

Right stop light not working, my 996 has aftermarket LED tail lights, I replaced both unit door new ones and the problem continues..

All other lights work fine (turn signals, hazards, reverse, night lights)

Thank you! I checked for 12v on tje 4 pin at the light with the brake pedal pressed without any luck… will have to trace that 13 connection… doesn’t look like a fun task, specially with no electric experience…

Hi @diegoestra71869

Check if there's 12V DC on pin 4 of the connector that the right tail light assembly cable plugs into, when the brake pedal is operated.

If there isn't and since the left side brake light is working, there may be a wiring problem between pin 4 on the connector and the multiple wiring connection point # 13.

Unfortunately I don't know where that is located. You may have to trace the harness wiring back from the right side (or the left side) tail light assembly.

Here's an image of the relevant part of the wiring diagram that may help.
