Heater wont heat by cral

I have a 98 explorer 4.0 xlt SOHC. I have replaced the thermostat, and the heater control valve--both of which were bad. Had the heater core checked and it is ok; good heat going in and out of it. I looked at the blend box and it is operational as to when i go from a/c to heating... I am at a loss any suggestions would be welcomed..
 
PS the fuse is also good
 
Thank you

Vent Problem by kaycee1

I have a 1995 Ford Explorer and a couple of weeks ago when I turned on the fan and set the knob for air flow I noticed the only direction the air will come out is through the defrost. The fan, air condition, and heat are all working but only through the defrost. Is there a way for me to check this out and correct the problem?

Heater not heating by dcvedwards

Hi all. We have 96 Ford Explorer with 4.0/5.0 engine. Man at Advanced Auto parts checked all four posts around heat valve. He said they're all hot. He thinks trouble is with "vent door." I found it behind glove box. The door CLOSES so that I can't see the fan turning when I turn on the heater. Should it be doing this? When the air is turned OFF, the door is left OPEN and I can see the fan blades behind it. The fan works fine. Air is being blown very well, but it will NOT heat up. I asked him about changing thermostat near radiator, but he said that's not the problem. And since all the pipes near heater valve were hot, he doesn't think that's problem either. What to do?

your blend door is broke, either insert a small rod into the actuator tip so that it turns the blend door or buy a new blend door and install it yourself.

My girlfriends 98 had the same problem. There is a black ball shaped plastic piece on the pass. side inner fender that has two vacuum lines going to it. I just pulled them off and plugged one in the other that fixed the problem don't know for how long? I believe that it's a storage tank for engine vacuum?

Ford Explorer - Fan Not Blowing Any Air by explorermom

It's freezing where I live and I have no heat because the blower is not sending out any air! I tried to search the forum but need help. The first time it wasn't working, I changed the fuse and it came back on right away. Now it's not working again, I replaced the fuse again but no luck. I am not able to afford to see a mechanic so if there is a simple check or fix (for a woman) I would appreciate any and all advice. Thanks!

Referring to my question above, can anyone please tell me why changing the fuse would work once but did not work again? Please help, it is a 10 below windchill here and I need heat!

Silly questions time.What year is the truck? Does it have electronic climate control? Was the fuse blown the second time you changed it? Does it send air at any fan speed? Does it work in defrost?

Auto Climate control works only on high air by delfino

My 95 Explorer, auto climate control works only in high air. The options for low and medium speeds don't work. Heat and cold works ok but only with high air. Also when I hit the auto bottom it don't work. Is there a relay I should replace or just the fan?
