WHERE IS THE HEATER CASE DOOR LOCATED ON A 92 COULD IT BE STUCK SHUT AND NOT LETTING HEAT INTO MY DUCTS? I HAVE NO HOT AIR.

1992 Nissan Sentra • 180,000 miles

I have no heat, have checked all the hoses and all are hot going to the heater core. Have changed the Temp. Gauge, checked to see if anything was clogging the air flow. Could the Heater case door be stuck shut? If so where is it located? I have air flow, just no heat.

NO HOT AIR

Check for malfunctioning engine coolant thermostat, plugged heater core, or low coolant level. Also check for malfunctioning blend-air door and heater valve not opening.

Air-mix door is within the heater assy. Check the cable adjustment and ensure the door is closing fully when the cable is pushed to heat position.
