#68 of 539 Ford Explorer 2000 AC
Jan 03, 2008 (1:41 pm)
We have recently bought a 2000 explorer that has a problem with it climate control. It seems that the air con doesnt work ( cuts out and goes extremely hot) when you travel up hills and long distances, usually through the country side.It has been back to the dealer in the city.The dealer said he rang ford australia and they have no idea. So back to square one. If anyone has any idea on this. Any Tips will be appreciated
#69 of 539 A/C problem sounds familiar
Jan 03, 2008 (7:05 pm)
FWIW, I remember when I worked on cars in the '60's and '70's they had a VCO (vacuum cut out switch) that would release the electric clutch on the A/C drive pulley during low vacuum operation (which occurs when you are going up hills or riding the the gas pedal hard or towing). Releasing the clutch would allow the engine to provide full power when needed most instead of having to run the A/C too. When the vacuum returned to normal (driving on a flat road at the speed limit) the clutch would be allowed to re-energize and the A/C would come back on.
If the VCO switch failed or the vacuum line cracked the same thing would happen as you describe. A lot has changed since then and I don't think they use VCO's anymore but your problem sounds familiar.

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 539 no vacuum to heater control valve

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.

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.

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. Thanks for your reply

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.

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.
