HEATER

2002 Lincoln LS • V8 2WD Automatic • 130,000 miles

My 2002 lincoln Ls v8 blows cold air out the vents but the heat wont work. The car is reaching normal operating temp not over heating so I dont think its the thermostat. Plenty of coolant I check every fuse in the car. What should I do next?

Need to test the heater hoses
with engine running and at operating temp heater fan motor on high open hood and check heater hoses by the firewall
if both hot you have a blend door issue CHECK FOR CODES
if one warm or hot and other not heater core need to be flushed
isolate heater core and flush
let me know
