#518 of 539 2002 Ford Explorer
Mar 27, 2013 (10:28 am)
I have a 2002 Ford Explorer. When I try to turn my heat on it makes a loud thumping noise and only cold air would blow. I had a "friend" look at it and he was able to reach in through the glove compartment and move the stick to heat. The heat worked perfectly fine and was hot however once the truck was turned off and then back on the stick was stuck again and I only got cold air. I took it to a mechanic who just told me that he was able to move the stick back to hot but the heater core was shot and needed to be replaced and that until it was replaced I can either have air conditioner or hot air but not both and cannot switch back and forth. He said it would cost $1,000 to fix the heater core. I obviously don't know much about cars but it seems that if the heater core was shot I would not get hot air when I turned it to hot. Does this make sense to anyone and do you think the mechanic is correct. I feel like I am being taken advantage of. Please help.

">Hello, We also have a 2002 Ford Explorer. We had the same problem and our problem was not the heater core. It was actually the blend door gear, and alot cheaper than the heater core (about 35 bucks), and its easy to check. If you take off the panels underneath the steering wheel and the center console and its a little bit of a tight squeeze but lay on your back on floor board and look up towards the radio (on your back it would be the left side) and stick your hand up there and feel for a box, you will see it, its probably white. The blend door is hooked to the box and if you pull it out (the box) (you will have to unhook wires and you can open the box, look at it and tell if the gears are striped, (which is what our problem was) go to auto zone or online, and order a new box (30 some dollars) replace it and voila! your truck will work and as a quick fix you can pull the rod hooked to gear out of the box, and put it back into the slot (hooked to the blend door) and leave the panels off your truck and each time you turn the car on, reach under there and flip the gear manually. Super easy! once you get part just replace it all and your good!
If you google 2002 ford explorer blend door gears, you will see the box im talking about, and you will be able to tell which part you can "temporarily" take apart and stick back into the truck to have a quick fix if they have to order the part.

The diagnosis sounds correct. The cost may vary though. Depends upon which door is sticking, and where it is. I would say $450 to $1000 is the range.
#521 of 539 Air going warm then cold in 98 Explorer, more often when High Temp outside
Jun 14, 2013 (11:24 am)
98 Explorer , you can start it, turn air on and it is cold, drive a bit and as car heats up or if it is really hot outside, will start to blow warm (not hot) air (like freon is low). Then after a bit it will begin to blow cold again. For the last year we have not had to change the Temperature selection knob to get heat, just change the air/heat selection knob. So, Blend Door or Cycle Switch? Also, rear air fan makes awful noise if on, how hard are these to change out?

OR, (and likely), a bad expansion valve. Not a difficult fix - does require an evacuation, obviously. The part is about the size of a nickel and doesn't cost a lot more than that. Certainly not a big job, other than the evac and re-charge. Usually you need an equipped tech for that.

Thanks, will check out the part, get it and see about getting my mechanic to fix it. He is good to me when it comes to labor, so hopefully will be an easy fix.

So would the climate control actuator and "blend door actuator" be the same thing? My 2008 is having the exact same issue.
#525 of 539 A/C only blowing hot air 1998 explorer sport

My 1998 explorer sport only blows out hot air. I charged the A/C with refrigerant yet it hasn't solved the issue. I'm not very great with cars so any help would be much appreciated!

Did you ever find out what the problem was with your A/C? My 2010 does the same thing. It cuts out and blows from my defroster for a couple minutes before switching back. I've taken it to the dealer MANY times but they claim it never duplicates while in the shop. Does it to me in a daily basis and seems to be getting worse.

I need to change the flap control to stop sucking up the air from the outside. I have a 2003 Ford Explorer. When I turn the control from inside to change the direction of air,(floor, defrost, max, etc.) It blows lightly out of all vents no matter what I do. Can I fix this or is this something major? When you have the controls on max, it is supposed to recycle the air from inside of the cab but its still takes the air from the outside. I looked behind the glovebox and I see the vacuum motor, is the flap control located there?
