Finally an answer!!!!!! I've been searching forums and google with no clear cut answer. To recap, the cooling fans are running at top speed even with the keys removed, the AC does not work and the temperature stays buried at 160. It is either the thermostat stuck open or the temperature sensor has gone bad. I replaced both and the problem was still there. What every answer has failed to mention is that after the repair you must connect a code reader and reset the engine codes. Not even the dealership could help me. Also I did not even have a check engine light during this issue but the code reader did show a P0128 code which is related to engine temp sensor or thermostat.
