Sounds like your thermostat may be stuck open. When the wind moves in front of your car, it chills the Radiator and drops the temperature. All the other settings for Heat, like ductwork and waterflow are in the same positions sitting as moving.

SOURCE: lincoln navigator front heater cool

this is caused by the main cabin temp blend door actuator motor, in order to replace it or even check it the dash must be pulled out.

SOURCE: 1999 Lincoln Navigator stops blowing hot air

Since your blower is working and it is a heat issue,thats where we'll start,First thing is have you checked the coolant level in the radiator when engine is cold,make sure it is filled to top,next verify you have coolant in reserve ,Start your van and get it up to normal operation temperature,If your heat gauge on the dash works correctly it should be 190 degrees,Now lift the hood and locate the two heater hoses going into the heater assembly at the fire wall,Both hoses should be hot to hold on to,if both are hot and no heat inside your problem will be the blend air door in heater assembly.
if neither hose is that hot you need to replace the thermostat in the engine to get it up to 195 degrees.
if one hose is hot and one is luke warm then the heater core is blocked and to blame. hope this helps you.

check your antifreeze level, if its low then it will cause it to blow cold. or you could have a blend-air door problem under the dash: look for a loose vacuum line behind the glove bow for this. Or you could have a bad heater core.

Car over-heats and heats blows cold air


It sounds like the radiator is low on coolant.
You could also have air pockets in the cooling system if the system is not full of liquid.

Heater blows only cols air- one line going into heater core is hot, the other cold.....1994 lincoln town car


sounds like a restricted heater core. if you remove the heater hoses from the engine, pour some cooling system cleaner in. let it sit for 10 or 20 minutes, then you can flush with a garden hose.

Could be the vacuum motor blend door problem where the plastic door inside the dashboard is not properly being angled to direct cold air and to block hot air from coming into the cabin.

I just replaced my thermostat, and had my heater core blown out for clogs etc, and my engine coolant is still at the right level in my reservoir, but I still getting cold air when I turn on my heat any...


Check to see if the heater control valve is not opening,feel bot hoses,and they should behot to the touch.Did you bleed the air out of the cooling system?Coolant will not circulate if this is not done.

My 1993 Lincoln Continental heater only blows cold air. What could be wrong?


If this has the automatic climate control, there is a sensor on the passengers side down in the AC/Heat passages by the blower, it measures air temp and adjusts accordingly. Another thought would be the door that should close for heat is stuck or you have a vacumn leak or a bad actuator. You have to remove the passenger compartment shield that is on that side to get at these items.
