I recently purchased this charger it was a police car. I replaced the cooling fans due to the plastic that holds them in broke and the blades went into the radiator . ( a chance they were binded up while electric was going to them) I have A Code P0480, the Fan kicks on 20 sec after cold start runs constantly and seems to be running at a high speed . Temp sensor good , All relays and fuses are good ,wiring is all good. If I clear the code the engine light and code pops right back on 20 after start along with the fan .

Also no gear indicator PRND and the A/C not working . The fuse block has constant power for the a/c clutch but the switched power from the dash control doesn't seem to work along with the illumination of the heater controls If you jump the relay the A/C works fine . I also noticed the wipers will stop in mid position of the windshield after you turn them off if you jog the switch you can get them back to resting point I am thinking the FCM may be bad .. Anyone ever run into this problem??
