HELP !!!!
I have a 24,000 mile car that now has no cooling fans or ac clutch action.I've changed the coolant sensor at the thermostat. The thermostat is brand new. I've checked the fuses and relays at the underhood panels and at the dash panel. If I unplug the coolant sensor at the thermostat the fans work but I get a service engine light and the darn thing runs really cold blooded. I understand that somewhere else is located an additional fan switch but I can't find it....help
