Hey guys, I got a call today to have a look at a 2004 Colorado which had a r/s installed at the dealer. The problem is that the unlock option will only unlock the drivers door. The dealer has told the owner that there is no other way to make all doors unlock on this truck. Is it possible that they used the priority unlock wire???

Thanks Craig

depends on the model of RS they put in.... some have the ability to "double pulse" the unlock wire or else have a second unlock output......

If they used the white wire at the BCM(black plug, pinA12) it will unlock the drivers side only with a negative pulse. You have to use the dark blue at either doort harness....
