An update to the whole speedometer issue. Everything worked great until my trip to Orlando. 2 hours on the interstate, and the speedometer starts fluxing and drops to zero. Of course, lost the cruise control and odometer. Swapped vehicles and returned 4 days later, battery was dead. Replaced battery and test drove, speedometer worked but AC is dead. Tech is telling me the AC compressor is toast and couldn't find a problem with the speedometer wiring harness or any error codes. I'm leaning toward an instrument cluster problem(specifically the speedometer portion once it heats up). What a POS.
