I pulled an oem pcm out of a 05 turbo S cabriolet this afternoon for a buddy and inspected it (it was fine- the bose amp was the problem. He needs one of those if anyone is selling) and immediately replaced it.

After it went back together, the lock button and rear defrost buttons don't work.

The key fob will not lock the doors and it gives a short weak double honk when trying to lock the car with the fob. I thought maybe the frunk or engine cover, glove box, or console lid were open. All of those are fine.

The buttons on the right side of the horseshoe don't even illuminate. I double checked all the plugs are good. Drivers side buttons have no issues.

The frunk light, engine bay light, dome lights - none of that works either.

Im thinking it has something to do with central locking maybe. You guys been through this?? I read something about the interior motion sensor possibly.

The radio isn't asking for a code or anything. Its fine.

 

Ended up being a dome light fuse. Fixed all the issues mentioned above!
