95Explorer heater ventilation - defrost only..help!

[mustang960]

Members,

I have 95 Explorer that when I turn the heater on, the heat would only come out on the defroster vent up by the windshield regardless of the knob position.
I can not direct the heat to any other vents (feet, top/face, or any others).
Any ideas what to check first?..
Thanks!

heater - defrost only

Look on the left side of the engine (from the front) about halfway back next to the exhast manifold. There is something that looks suspiciously like a bomb - it is round and about 5 inches in diameter. That is a stupid!!! vacuum tank. You lost a vacuum hose connected to it. Feel around towards the firewall, you'll eventually find it. Your vents are operated by vacuum motor.

Good luck

Ed

Just thought I'd let you know that I had the same problem and got the same fix. Found out on the way to the dealer that it also operates the four wheel drive cause it was a snowy day & I was slipping & sliding on the way .

> 95Explorer heater ventilation - vacuum tank question

Thanks for the info Bill,
I now have question:

Does that stupid vacuum tank also control the four wheel drive functions somehow ?!... I traced a couple vacuum lines that go from the tank to an area by the passenger side headlight. What are those connections ?..

Thanks again for any replies.
