On my 17 Z the passenger compartment vent has the temperature display in a little window beneath the vent mine is not displaying temperature any thoughts on what it could be or has anyone has this issue. Thanks.
SYNC: Press to link all climate
zone settings to the driver settings.
The SYNC indicator light will turn
on. When the passenger
temperature setting is adjusted, the
SYNC indicator light turns off.
Remember, that's a guess! Damn thing could be broke!

Just a guess, but perhaps the part itself has gone bad. Are you able to control the temp on the passenger side from the HVAC unit in the center console?

If you have access to a scan tool that can read body codes look for U151C which indicates that module K33A has lost communication with module A34 which is the HVAC control in the center dash area.
I would say check Fuse F22UA in the underhood electrical center but that fuse also supplies power to the center dash information display. I suspect you would notice if that display wasn't working.
Here is what the connector on the back of the module looks like:
The problem is either a lack of power, ground, communication signal, or a failed module. The power comes from the same fuse as the center dash information display so if the center display is working you can assume the fuse is OK. That leaves the wiring and ground connection or a problem with the data bus. If all of those are good then the module needs to be replaced. Whatever, you will need to pull the passenger side dash pad where the module is located and check voltage, ground, etc.

Thank you when I ran the Autel scanner I had a code for the amplifier this car at one time had an aftermarket system with a subwoofer I took it to a shop and they connected back the amp and other components that were disconnected and I have not received a amplifier code again I'm wondering if they screwed up the wiring when they disconnected the old system to sell the car.
