You can buy the keys, and the little bulb at the dealer. They are both cheap. Easy fix.

Run the Onboard climate control

diagnostics and you will most likely discover the Duo-valve is stuck.
You can give them a tap(a firm drum like thump)with the end of a wooden screw driver handle.That usually frees it up,if not fixed then you can take it apart,clean it and lube it and problem solved.
Post your data values 1-8 only and errors in the error mode.Write them down to post here and then in error mode press both auto buttons at the same time to clear the error block.

It is a tiny

bulb only attained online but by the time you pay shipping cheaper at the dealer.
You will need a set of radio keys to pull the cc module,flip it over ,twist out the socket and replace the tiny bulb,install back in and job complete
