My GPS/information screen reads "check A/C. Connection." Now, it will not allow me to access the climate screen.

Start with a scan for codes and get the A/C pressures check with a manifold A/C gauge set. With the readings we can start to diagnose this problem.

You need to do the checks in the first post. If you cannot get a local A/C mechanic to inspect, some hands on diagnosis needs to be done first.
