    Mine doesn't get hot and blows through all outlets instead of just the defrost or the front.

Heater control valve..heater core clogged ..circulation to heater control valve weak restricted or closed..do a radiator flush and fill thoroughly backflushing the heater lines with heater open all the way...if no smell or leaks inside cabin passenger area or losing coolant you should fix teh problem... other issue could be control head not opening blend doors properly

Heater will not blow hot in my Ford Explorer.It has plenty of coolant. Any easy fixes?


If the heater hoses are hot, odds are the blend door that controls air temp is stuck or otherwise not moving. There are three blend doors under the dash.
You may need a shop manual to get the instructions on how to test them.

Can not turn on my heat..ford explorer


you may have abad hot /cold blend door acuator.its bolted to air box. also make sure both heater hoses going to heater core are hot,if only one is hot and the other is luke warm or cold then you may have a clogged heater core,remove hoses (@ core) and flush with water hose go both ways a couple of times. good luck hope this helps.

Over heating


Check to see if your water pump is leaking radiator fluid through the weep holes, or maybe a wore out drive belt. good luck.

I have a 2000 ford windstar no heat still


My 99 windstar did this too. It was the blend door that the actuator motor goes into was broke. When you pull the actuator out look into the hole and see if you see a d shape piece coming out of the box if it is not d shape it is broke check out this site great photos

No HEAT 96 Ford Explorer


i would guess your heater blend door is sticking. It is a rectangular door that moves back & forth to allow either cold air or hot air or a mix out of your vents. This is not an easy fix. But first be sure you heater hoses have hot water flowing in and out of the heater core. Under the hood you should find 2 hoses going into your firewall on the passenger side.
