Make sure the heater core is in the open position by using the shut off valve and turning it to open. next, you may have a malfunction in the direction door the directs the air flow in the dash. a lever may have become lose or separated. may be a bad servo motor not directing the door to move to the heater position. i would start by checking that shut off valve first on the heater core.

SOURCE: my heater only blows cold air-'98 ford explorer

Hi Bri,

That is usually the first symptom of low coolant. Not enough water in the system to circulate through the heater core. Has it been running hot?

Check the coolant level in the radiator

Best regards,
Mike

02 ford explorer 4.0 overheating and suddenly blowing cold air, then hot again while engine runs cool but not long


Most likely you have air trapped in your engine, particularly in the heater loop. You need to properly bleed the air out of your radiator cooling system. The hot and cold blasts of air coming from first hot water followed by air.
Read up on how to bleed air out of your radiator system. Some systems are very difficult to bleed.
If after doing a good bleed of the radiator system the problem returns, you may have a bad head gasket or other leak in your cooling system which is injecting air into the cooling system (radiator/water cooling system).

2005 ford explorer will only blow cold air no matter what ther thermostat is set at, and it makes a clicking noise when it is on, why is this....please help.


You may have a thermostat that is stuck closed.  If it doesn't open, hot coolant cannot reach the heater core, thereby blowing only cold air.

Temperature Control not working on 1999 Ford Explorer


Sounds like your temperature actuator is not moving or your temp door is broken. On max a-c ,coolant is shut off to your heater core allowing only cold air in.
