2000 X A/C & vent problems!!

I have a problem with the A/C vents, they will only blow out of the top defrost vents. I did get it to come out the vents the other day when it was raining; I can only figure out that there is some kind of vacuum leak outside under the hood. Has anybody else had this problem? Any help would be greatly appreciated....<O</O

Check under the passenger side dash area. Have heard of a vacuum hose that gets pulled off easily that creates vent control problems.

I also changed your title to help get more responses. I've seen this subject many times but cannot remember the exact cause. Hopefully, someone reading the title will know off-hand.

Diesel? Is your electric vacuum pump working?

Definitely check the vacuum hoses under the dash. My wifes Taurus had this problem where it would only blow cool air through the defrost vents. With a little investigating, I found two vacuum hoses off the regulator behind the climate control panel. Hopefully the X is easier to work on.

The motor is working all the time. I have tried to check the vac lines around there and behind the glove box. No luck. I do however think when i put it in 4wh drive the light comes on but i don't think the front tires are pulling. I also have problem when idle of not having power stering. Could either of these be the culprit. I also have searched through all the threds with no luck finding the problem.

Thanks for posting.

Can anyone tell me if the vacuum motor should run all the time? I only have the ignition key on with nothing running that should run on vacuum and the motor runs constantly.

Angry Update

Just thought i would let everyone know that I ended up taking it to the dealer. It was the 4WD Vacuum Switch Part # F81Z-9H465-BA. Ended up costing me $268.09 with tax.

$179.90 Labor
$ 47.50 Part
$ 17.99 Misc. Shop Supplies
$ 22.70 Tax

What a rip off!

BTW the vacuum pump is not supposed to run constantly.

WOW - We are in the wrong bizness - that labor rate is something !!!
But at least it's fixed now...
so go out and "test" it !

But the old saying goes:
"You're not paying me for what I do,
you're paying me for what I've already learned and know" !!!

Heck, I've even used that in my consulting bizness :-)

I had the same thing happen on my 02' TJ, just had to fix the hose which is very small diameter on TJ's. I had a small cut in it so, I cut the hose in half and used the gray casing for telephone wire and that did the trick. Not sure how this will apply to your situation, but may help someone.

I currently have the same problem on my 2000 V10 excursion.

The PVH valve is indeed part # F81Z9H465BA and the local dealer wants $86.31 for it.

For now I have 'fixed' the function of the HVAC by disconnecting the vacuum connector from the PVH valve and plugging the line.
