One of my friends drive an Acura EL (only avaliable to Quebec, it is exaclty the same car as a Civic 98+ but with Acura badging) Anyway. He have power remote door lock. Here's the problem, when he try to unluck the door with the remote, all doors except drive door unlock. He have to unlock it with the key. Anybody experienced this problem before, maybe a bad connection or something. He dosen't want to take it to the dealer and get ripped off so I'll try to help him with what you give me.

Thanks in advance guys and gals!
