no heat

I have a ‘17 Explorer that doesn’t produce much heat anymore. Fan speed seems to have not very much change between the lower ones until 6 and 7. So thinking a resistor? Blend doors are cycling through defrost, forward and feet area. On the rear you can definitely notice all the changes in...

My Explorer is not reaching operating temperature. Temp gauge stays completely on cold for 20 minutes and then will only just budge about a quarter way up, rather than reaching the halfway point between hot and cold on the gauge like it's supposed to. I know that the main three culprits for...

Hey everybody! So I have a 2001 Ford Explorer Sport Trac 4X4. Replaced a cracked radiator. Filled up the new one and let it run for about 12 mins. No leaks but I noticed the heat isn't working. The temp gauge had it running right in the middle but I didn't check the hoses from the heater core or...

I am going to be breaking into the dash this weekend to identify if it is the blender door on the passenger side or the Heating core... before I get started I'd like to have parts on hand vs go seeking. 1.) what is the best way to identify if the issue is blender door vs heater core...

I have a 99 Limited 4.0LSOHC with the EATC system. I discovered today that I have no heat. A/C works great and can switch over to defrost, panel or floor vents with no problem. I am not sure where to start looking for the problem as I have understood the blend door is a problem if you are...

HVAC issue here. Can someone describe how this system operates for me please. I have dual zone climate control, the passenger side does not get any heat. Do I need to look for a coolant flow regulator, or a blend door actuator? What could prevent the passenger zone from getting heat? I am...

Hi all. First post here. I have an 03 explorer eddie bauer. 4.0L. I have absolutely no heat. I've removed the driver side actuator and am currently changing the flap manually. I can hear that it's going back and forth all the way. I have checked all the vacuum lines and they seem to be...

I have a 96 Explorer EB edition and the AC works fine and blows cold air but when I turn up the heat the temperature doesn't rise? There's still air blowing through just doesn't get hotter. I need the heater to work as I'm heading up to Canada for the Winter and won't last long without heat in...

any suggestions where to go? I did DATC diagnostics test to get no results returned... however I used to have a right(Passenger) Blend door code... I'm not certain if I cleared the error code before. (that could be the problem? passenger blend door stops all heat from entering the cab? I...

Hello: I have a 2001 Ford Explorer 4.0 and one minute the heat was blasting the next thing it was blowing cold air. I've changed the thermostat, water pump, flushed the entire cooling system and it's still blowing cold. Any advice on what I can try next or what you think the problem is? It's...

So have 05 explorer 4.0L 4x4 also with rear ac/heat. Problem is no heat when not moving. The core gets HOT. While I was low on coolant, I topped it off and same issue. Lots of heat while driving, but come to a stop and starts to cool off . Seems like outside air is "pushing" through the...

Hey guys, I dont want anyone to be out in the cold this winter so I made a video on how to diagnose the heating system in our trucks. I go through, step by step, each common problem that causes you to not have heat in your truck (and this can be applied to any vehicle). Let me know what you...

Hi I'm new here and have tried many help sites and mechanics with no luck just lost $. So my 99 explorer limited engine temp always has run cool temp gauge never reaches half way. Also it has no heat but the AC works great. Changed the thermostat twice.. No luck the actuated door (?) in the...

I did not want to threadjack the 'Engine underheating?' thread, so I am posting a new one. I just noticed the same problem listed on the other thread with my ’00 Limited. The heater is just blowing luke warm air. The heater used to blow really hot air to the point that placing my hand near...

Hi. I had an engine swap recently. I went with the lowest price for the install and now I find myself trouble shooting everything he either broke or didn't reconnect. Anyway, since its starting to get cool in the mornings, I notice the heat on the passenger side blows cold air. When I...

I have a 01 Ford Explorer w/ 4.0L V6 engine. The heat was coming and going then it just stopped blowing hot air all together. I checked the radiator and the cap was cold so i changed the thermostat and it didnt help any. The lower radiator hose is cold and the upper is hot but not that hot. The...

This is my how to for replacing the blend door actuator on the 3rd Gen Ex. The Blend Door Actuator controls the hot/cold temperature in the vehicle, not where the air is blowing from or fresh air/recirculated air. While researching this issue I found several discussions, but no definitive how...

I just bought a great '97 XLT to add to my ever growing collection of Explorer/Rangers. It has a few issues I need to address. Currently it puts out moderate heat, at first I thought it was a thermostat because the temp was staying cool on the gauge. More like not rising at all. I've come to...

We have just replaced the radiator cap, fan clutch, water pump and thermostat in my 2004 ford explorer and it is still overheating. The radiator was also flushed. In addition there is no heat coming out of the heater. I don't know if it related, but the air does not blow out of the inside...
