IIRC the old style switches passed the signal thru the other switch, but I think this application uses a BCM to control the motors and one switch wouldnt kill the other?
Does the other switch in the other door work? Do the remotes work?
1. if other switch works, replace the defective switch.
2. if remotes works, inspect wiring from BCM to the switches, possible bad BCM.
3. if neither unit works, suspect bad BCM.

Nuff said.... I would still look at the wiring for the switches tho..... Backprobe the BCM for the function that doesnt work from the door switch......
