#70 of 129 Re: A/C + HEATER SEMI-BROKE 2002 Ford Explorer. [harkess] by ryan_green Jan 06, 2008 (5:02 pm)
Replying to: harkess (Nov 24, 2007 2:45 pm) FOR ALL WITH THE PROBLEM WITH THE CLICKING UNDER THEIR GLOVE COMPARTMENT. I own a 96 explorer and had the same problem about 2 months ago. it turned out to be a broken blend door. I dont remember where i bought mine but im sure you can just google it. Its an easy 15-30 minute do it your self job.   Now about the neon green fluid...just today this has happened to me and i dont know what it is. I think it may be antifreeze. If it is antifreeze what do i do about it?
#71 of 129 no vacuum to heater control valve by bbelasco Jan 14, 2008 (5:25 pm)
1998 ford explorer 5.0l. I cannot get any vacuum to the heater control valve so it opens or closes when the temperature is changed. As a result I have cold air only. If I push it closed I have heat, Unfortunately there is no vacuum to hold it closed. Does anyone have a clue where I can begin to look to find the solution.   Thanks Replies to this message: ryan_green (Jan 15, 2008 10:24 am) bbelasco (Jan 15, 2008 4:39 pm) fordexploreguy (Feb 05, 2008 10:35 pm)

Replying to: bbelasco (Jan 14, 2008 5:25 pm) I dont know how it is on a 98 (not sure if its any different thana 96) but there isnt a vacuum that holds the blend door shut. It is mechanically moved by a motor thats is placed on the top of the door. Replies to this message: bbelasco (Jan 15, 2008 4:39 pm) fordexploreguy (Feb 05, 2008 10:35 pm)

Replying to: ryan_green (Jan 15, 2008 10:24 am) I had a 96 and had to replace the entire heater box due to a broken blend door. The blend door is controled by a motor that sits on top of the heater box. The heater control valve is located against the fire wall on the passanger side. It is an inline diaphram devise that controls the flow of water into the heater via of a vacuum. My blend door is working fine, the issue I have is lack of vacuum to the valve.

Replying to: harkess (Dec 26, 2007 7:54 pm) This is BJohnson. Can you tell me exactly how your husband got the glove box out? After you open the glove box, what do you do to pop it out, and did you say that the lever you need to close will be to the left? I havent had any heat or defrost for 3 months and am almost desperate to get it fixed. Shops want like $900 to fix it! Thanks for any help you can give me.

Replying to: harkess (Dec 26, 2007 7:54 pm) this is bjohnson. I am trying to close the blend door as you spoke of. I got the glove box out and I can clearly hear the ticking, but I dont have a clue what I am looking for in order to push a tab forward to close the door. Can you please tell me anything to help me find it? Thank you for your time.

Replying to: bbelasco (Jan 15, 2008 4:49 pm) bb: I did the fix described at the web link on my followup message (#64). It's working so far. The only thing I did different was to get an aluminum bar about 1/8" x 1/2" and bend it in an L--shape, so that I could use it as a lever to move the door to one side before putting the motor back on. Once I figured out which way the V-notch was oriented (see the picture in the web link) I tried to drill the hole for the finishing nail to bridge across the top of the V. That way, when the white post rotates to move the mix door, it has something to push against in both directions.   I hope this helps and makes sense. Good luck! -H Replies to this message: bbelasco (Jan 25, 2008 12:48 pm)
