Flush out the heater coils. Disconnect the 2 hoses that go from the engine block labeled Heater that run from the front of the engine to the firewall. These are 5/8" hoses and a standard water hose repair female adaptor will fit nicely. Connect you water hose to this adapter and run clean water through the hoses until the water comes clean. Remove the adapter and connect the hoses back. You should bet very hot air back again.
