The first thing that needs done here is to have the fault codes checked using a scan tool that can plug in and communicate with all computers to see what codes are set.Once this has been done any codes set will need to be diagnosed to locate and repair this fault here.This sounds like an electrical ECU fault causing the heater/ac issue wit hthe blower as well as the gauges to act up.I have seen body control ECU's fail internally needing replaced to correct faults like this here.The first step though will be having the codes checked in all computers to see what codes are set then diagnosed and repaired from there.
