I REPLACE THE HEATER CORE AND NOW ALL I GET IS LUKE WARM AIR NOT ENOUGHT TO DEFORST MY WINDSHIELD. WHEN REMOVING THE ELECTRICAL CONNECTORS FROM THE RESISTOR ONE TONG BROKE OFF AND I HAD THAT FIXED BUT I STILL CAN NOT GET ANY HEAT.

See if vacuum valve on engine is not getting vacuum if not you'll get no heat both heater hoses should be hot. Then check air intake valve and vacuum valve selector. Also check for vacuum leaks.
