Have the Montego Premere. When temperature dips you can't change temp setting or the heated seat won't work until the car heats up. If heater controller is left on manual it will start up where the setting were when car was shut off, but can't change settings.
Heater controller doesn't work with temperature under 25 degrees on 2005 Mercury Montego
