I’ve replaced all 4 brake wear sensors but I’m still getting the dash warning light for pads and it’s so annoying. Is there something that I’m missing? Please let me know. Is removing the pod light the solution in this case?
Perhaps coincidental, but my drivers side rear side light keeps going out. I replaced it and it worked but then it didn’t.

They are simple devices, a loop of wire in a plastic fitting that fits into the pad backing plate. When the pad gets thin, the edge of the rotor chews through the plastic and wire, and opens the circuit. You can see this clearly on the sensor, or check it with a multimeter on the ohms or continuity-test setting. There can also be a wiring fault in the harness but if the warning light first came on with a worn pad, and you replaced that sensor. then it is probably a connection problem at that corner. Or whatever corner you last touched.
The pad-wear sensors are all connected in series i.e. a daisy-chain back to the dash.
What year car? Do you have the wiring diagrams?
Driver's-rear marker light is only an issue on '89+ cars with a PSD, where the pump assembly in the rear quarter renders the marker-light mostly inaccessible.

It’s an ‘87.
The brake pad sensors were giving me a warning light, AFAIK they were original to the car. After futzing with it for way too long I went ahead and installed new sensors in all 4 corners, but the idiot light is still on in the pod. It’s driving me nuts!
That drivers side marker is giving me another idiot light, “tail” light on the pod. I changed all of the bulbs in the back of the car, using Rennlist documented bulb numbers, but that one bulb, now a 5008, just wont stay working.

Same with the rear marker light, most likely corrosion in the light socket. Clean any visible corrosion and treat it with Deoxit. Also make sure the rubber boot is in good condition, lots of water back there in the rain.

Once when doing a major on the brakes, I accidentally plugged the sensor into the unused hole in a barrel connector. It's an easy mistake even this caveman can make. Easy to diagnose with a small mirror. Look up in the bottom of the barrel, and if you see wire terminals in any of them it means something is plugged in wrong.
