So I'm getting this annoying thing going on with my power door lock on my passenger side....

When I try to use either the remote to unlock the doors or use the drivers side power lock control, the passenger door will not unlock....ever.

When I use the passenger side lock control, it will unlock the door once out of every 2 times tried. Any ideas on what part needs to be replaced?

When I hit the door unlock, you can see the door pin try to unlock, but no joy....

 

I have same problem on my '97 Dodge Intrepid, but sorry, I don't know how to fix it.

 

sounds like a fault with the solenoid. Easily changed if you can get the trip panel off.
