Not sure about your AC but do a Google search or search this forum for tach issues. The 2006 model year is notorious for tachometer failure. My 06 did it and you will find gobs of others 06 trucks that have had this issue as well. Oddly, it only seems to be the 06 trucks. Maybe a faulty design that came out during the 2006 overhaul and Chrysler fixed for 2007?? To the best of my knowledge no one has ever definitely pinpointed the exact cause but I have read a lot of speculation about the tach stepper motor, the component within the cluster that controls the movement of the tach needle. I had intended to remove my cluster and take it to a local electronics repair shop for troubleshooting but I traded the truck for my current truck before I could get around to it.
