1993 chrysler fifth ave.3.8L Replaced ignition switch (acustar tilt column) due to air bag warning light on and no blower fan, everything now functional but no heat, blower control works in all settings on "auto" and manual but blows no heat, checked temp of lines into firewall inlet@180 outlet @70. is there a flow valve or other form of control to regulate the flow of coolant thru the core?
if not any advice where to look?
