Door Lock problems
 

Hey guys have a bit of a problem and I need your help

My drivers side locks and unlocks with my key and the inside switch
but the passenger side doesn't lock with the key
I also notice that if I keep locking and unlocking the car with the key
or from inside, the locks get slower, and the windows go up and down slower
I don't know if its my battery.. but my car starts fine...
and the sunroof works fine, lights are fine, etc
possibly a fuse? but then it wouldn't be working at all
I'm not exactly an expert on cars so i'm hoping someone else has
had this problem? Or a similar problem? The passenger door doesn't lock Or unlock
unless you do it manually.


Also guys, on my second unlock button the front or rear blinkers don't blink. Any ideas?
