Help!! I have a problem with my passenger side door lock not wanting to go up and down like it is supposed too. It tries to when I push my lock/unlock button, but most of the time that is all...TRIES. I have another problem that I think is an addition to the door lock problem. My radio dims in and out recurringly. I have read that this is due to some soldering problems, but I didnt hear anything relating to the door lock on the passenger side. The reason I believe these two are due to the same problem is two reasons.

1. I hear a clicking noise like a switch behind my radio when I try to lock/unlock the doors. It is pretty loud.
2. A few times I have held the lock/unlock button down, and my radio would dim.

However, my radio dims all the time, so I may have two problems and just be totally wrong. Any ideas? Im thinking I have a short in my radio and my locking gear in my door my be bad, I just dont want to check into it and come up empty handed.
