It seemed pretty simple, but when I got done, the pneumatic lock system no longer worked and the seat belt alert light (center ceiling by the sun roof controls) started blinking even tho we're buckled in. These two problems started at precisely the same time: no problems before I replaced the door panel, but problems immediately after I replaced the panel. I took it apart and reassembled but but couldn't see how this could be been related other than the door lock arm that connects to the door handle. What could I have done replacing the door panel to cause this?


Thanks for any advice on any of these three issues. -Harv
I know EXACTLY what the problem is here, because I have undergone it before. You have a burned out fuse as a result of the wires that connect the under-door courtesy light being shorted to the frame of the car. The short may still exist, or you may have hit it as you installed and then broken the short again. Either way, you've got a fuse gone which is causing (for whatever reason) the constantly flashing alert light.

Replace the fuse once, if it pops again then you have a grounded out courtesy light. If it doesn't, you grounded it out during the installation.
