After coming and going intermittantly for the last few months, it's now not working at all. Tried disconnecting and reconnecting the battery, nothing. It has power, displays one short dash and two long ones unless I try cycling through the various metrics that are available to look at on it. It will go up or down numerically, but if I stop on one number and select it, nothing. I've tried disassembling and cleaning the controller and even bought a used one to try. It does the exact same thing. Also the fan blows at maximum all of the time unless I pull fuse number 43, Heater and A/C Programmer. No codes are showing on the car either. Any ideas?
