I have a 1998 Ford Explorer. The A/C works fine at idle up to moderate speeds. Once it is at highway speeds, then the A/C turns warm. When I slow down the A/C gets cold again.
I don't know if this is a vacuum leak under the hood somewhere, or if it is the under the dash door problem. Any help appreciated!
how much paneling did you have to remove to even rig the kite string?
dash.http://www.p71interceptor.com/eatcswap/blenddooractuator/Photo0029.jpg
It is really kinda hard to get to, but if you can manage to get to all the screws loose great! we only had to take off the panel near the floor to get to it, but when you get the screws loose, and take out the box, you have to open it up and look at the teeth of the gears, if they are not broken off or chipped then thats not your prob. my gears were broken. you can do 1 of 2 things. if the gears are broken, you can go to an auto store and order a new actuator, which is around 40 some dollars, and then just put the new box in, replace the screws, and your finished....lol i actually have a quick fix solution while your waiting on the part to come in. when you open up the box, there is a piece that sticks out of the box, that fits into a slot in the dash that connects to the blend door. if you take that piece out of the actuator, just that one piece....and stick it back in the hole in the dash, you can manually turn the heat on by flipping the piece either forward or backward, but the blower will have to be turned on for it to stay on. but this is a quick fix and it will give you heat, until you get that box replaced. if you have any questions, or this doesnt make sense let me know. thanks kasey
Thanks so much for the info. I will be trying this soon because IM COLD!

Thanks- :lemon:
I've also had problems with the blend doors but I seem to have a more pressing issue, which is the blower motor, which is not operating by way of inside control knobs My blower was working intermitantly as if it had its own mind. At this point the blower will not operate. I have check the fuses and all are fine. I went to the blower motor to the wire connection and went an inch back and stripped the wire to except a separate wire which I ran directly to the positive terminal of the battery. As I suspected the blower motor worked. I can not for the life of me figure out where the interruption of power to the blower motor might be.
From the blower I followed the wiring harness back to the passenger side frame where I located a roughly, 2 inch by 5 inch box which had a cover on it towards the front of the vehicle which had roughly 3 or 4, 1 by 1 square black boxes which appear to be contacts which can be pulled out. Would my problem exist in these contacts?
Also, once I connected the separate wire to the blower from the battery terminal, I turned the vehicle on and then on full heat I went from high speed to medium and low spped, the blower shut off on the two lower speeds. I replaced the resistor at the blower motor housing with a junk yard one, assuming the problem might be there but nothing came from replacing it.
As I said I am confused to where the interruption of power might be and any help would be appreciated!!!! Prior to this problem of the blower not working, the blower only worked on high speed or off and I had a continues supply of heat that I couldn't control during the summer months. I understand why, by following other threads here, which were very helpful with blend doors, but I'm more concerned now with the blower not operating. Please except "my thanks" in advance for anything you can suggest!!!
My controls inside are three round knobs which control speed, temp and direction if this helps! Thanks Again!
Do I have a bad blower motor? Thanks for any help in advance.
When I have the thermostat in cool, I smell nothing, but when I turn it to heat, cant see due to the windshield is fogged up. Any news good or bad would help. Is it safe to drive in cool mode, until I can get it fixed....and whats the fix.

things work (rear defrost) that never even worked before but now this is broken. Any ideas what this could be?
Does someone out there have any suggestions?
Ted :sick:
Thanks Scott
PS: I did the blend door fix on my other daughters 03 CHerokee, not to big of a deal. I really didn't want to do it to the Explorer after watching the video!!
The problem was that I was not getting heat from the defroster when I turned the heater control knob to defrost. Heat only come out of the front vents no matter which position I selected. I removed the glove box so I could inspect under the dash, and noticed in the upper left hand side of the heat box that a control arm was not connected to the blend door that controls heat direction. It appeared that a plastic boss had broken off and a control arm mechanism and the actuator lever was no longer attached.
The fix:
•Drill a 1/8 hole through the control arm mechanism where the plastic boss had broken off.
•Using a self tapping 3/4” long screw to re-attach the control arm to the actuator.
•Please use extreme caution when hand tapping the screw through the control arm mechanism, it is possible to crack the plastic.
•Check for proper function of the heater directional control knob.
Done
have fun,
