The first thing that i would check would be the charge of the refrigerant. the next thing is to make sure that the clutch is engaging. and if it is not then check all of your fuses and relays. If it is then hook up a set of manifold gauges and read the system pressures and see what that tells you.

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.

The front heating on my 2001 lincoln navigator is blowing out cool air


This is commonly caused by a defective air temperature control blend door actuator or sticking blend door or in most cases both. This door is between the heater core and the AC evaporator cores and blends air from the hot and cold sources to give the desired outlet at at the dash registers. To replace the blend door requires the dash be removed from the truck so it is wise to have my guess confirmed by a Ford dealer. This is a common problem on the Ford Expedition and the Navigator model lines.

The heat is not getting hot in the front but the back heat blows out hot heat. Whats the possible problem?


If you can get cold air blowing out the front vents, the front heater door is not working properly. If you don't get air blowing out, check the front heater fan and its resistor block.

2002 Lincoln LS V6. AC blowing hot air but sometimes it works fine and blows cool. Is it a sensor problem?


its probably the compressor cutoff switch cutting your compressor off at the wrong time and causing your ac to blow hot. that switch is under your hood right on top of the engine easy to get to. I hope that helps you out!

That sounds like the Blend Door Actulator has decided to go loopy. I heard of people turning it to hot and getting cold, Normally when this bit goes it makes a click click noise
