Car Forum / Ford / Ford Explorer / April 2006Heat Stuck on Hot - Help!
Hi All, Thanks for stopping by my post. I'm having a problem with the heater on my 97 XLT. All controls operate as normal, except for the temperature knob. Regardless of where I turn it I only get HOT air blowing. All fan speeds and airflow positions work just fine, but the air temp is maxed out regardless of the dial setting. I'm thinking it has to be a damper door that is stuck someplace but I don't know where to check for this. I have a Chilton's CD, and it shows access to the damper door behind the glovebox, but that is for mechanical 'sliders' for the heater controls, not the electrical knob. Any suggestions would be greatly appreciated! Regards, Ken Google "blend door" for this group..... you might want to make a big pot of coffee.... > Hi All, > [quoted text clipped - 14 lines] > Regards, > Ken Thanks Jim... Found a little light reading, including your breakdown of the repair. Pot of coffee? More like a bottle of whiskey!! I'm not happy with what I read - especially considering it sounds like a poor design, but what am I gonna do. Could be worse - could be blowing cold air instead of hot. At least I can still drive it in the winter (I mostly drive my Mustang GT Ragtop in the summer). Coming to Calgary any time soon? I still haven't found a shop here I really trust. Thanks again for the tip and you previous info.

Getting vacuum ??????? I would check the simple things first If it's a ohv its next to the heater box If its a sohc its in front of the engine on the right side next to the timing cover > Thanks Jim...

I stumbled across this late last night. I'm going to give it a shot this weekend. Have nothing to lose! Cheers! > Go to: > > http://www.blenddoorfix.netfirms.com/ > > Have Fun! Again, first set your ac to max and see if you get cold air. If you do then it's the blend door. If you don't it's probably something else. I did the fix on my 96 B2300 (my 98 Explorer didn't break, yet). Watch out for dropping the actuator screws. If you do they will go behind the blend door box and you will never see them again. Also, definitely get a dentists mirror. It will help you determine where the pin and hole should go. I took my time and nailed it on the first time. Come see us again when the display on your radio goes dead. zoti > I stumbled across this late last night. I'm going to give it a shot this > weekend. Have nothing to lose! [quoted text clipped - 6 lines] > > > > Have Fun! Man, if it weren't for bad luck, I'd have no luck at all! I was pumped about doing this repair. Got the mirror, printed out the instructions and was ready to go this morning. Removed the actuator motor and looked into the hole only to discover that the hole was still intact. I put everything back together and slowly turned the nobwhile listening to the motor. I could hear the motor turning just fine from the cold position gradually to warm, then bog down then stop when the temp knob was at about the 10:00 position. It sounds like there's something causing the door to bind. Bummer. What's this you say about the disply going dead? This has happened to me a couple of times now but comes back to life. Sounds like another google is in order! Cheers, Ken > Again, first set your ac to max and see if you get cold air. If you do > then [quoted text clipped - 21 lines] >> > >> > Have Fun!
