No control over mirrors

[Logan Podmoroff]

Since I bought my truck I have had no control of my power folding mirrors. The previous owner said they worked before he had it detailed, took it to the dealer and they said it needed a new mirror switch. I installed the new window switch and still no function. I has an active code "U1519 LIN Bus 1 Lost communication with device 9". Looking at the diagram I have checked and have 12 volts on pin 10, a ground connection on pin 3, and 11 volts on pin 9. My understanding is that the 11 volts is a wake up signal for the mirror switch and that the voltage should fluctuate once the switch is responding. The switch doesn't seem to be powering up as the lights don't turn on when I hit the button to select a mirror. I don't have any experience with these LIN bus communication systems and am at a loss. Thought maybe some one else has more experience and can point me in the right direction. Maybe the new switch is faulty? I though about getting another to test it. If anyone has any other ideas let me know!
