Having a problem getting the dash out on a 97 Ranger. Have all but the "120" connector off. Dealer says there is a small bolt on it...but have taken the three square connectors off the engine side of the firewall and found nothing more. Cannot find any bolts or nuts on the driver side interior where the wires connect with a large fitting with a handle. Has anyone else taken the dash off or changed the heater core on a late 90's Ranger? Driving me crazy!
