The same thing happened to my truck. I thought i needed a new switch over there also. I took a multimeter an ran it front the master switch(aka driver door). From the relay to the passenger door. the relay wasnt closing. So i wasnt getting power to the passenger door. So I ended up needing a new master switch. I found one on dodgeparts.com for 83 dollars. I hope this might help you out. So if you have a multimeter, ill print you a copy of the switch off of alldatapro.com an email it to you if you need. Happy hunting!

 

Yeah that helps a lot. I will check the relays on the driver side and see what I find. Thanks for the help bttfman1and3
