2000 F53 V10 A/C Vents

Under a heavy load such as pulling a long hill, my dash A/C vents drop out which indicate a lack of vacuum to that circuit. I have looked for a vacuum reservoir or a auxiliary vacuum pump to no avail. After inspecting what vacuum lines I can see nothing looks amiss. Any Ideas?

A vacuum reservoir SHOULD have been standard in your application , there are check valves between the engine manifold and the dash system to maintain HVAC controls during long climbs and some members have needed to add a second reservoir to maintain dash system operation.

Reservoir is softball size/shape , black plastic , replacements/additional units are about $14 on Amazon or E bay.

I had to add one on my Dodge Dakota pickup to deal with the loss of control.

EDIT: I see 01blueox posted better info while I was typing , sorry for the duplication .

Vacuum reservoir should be in the passenger side wheel in front of tire. Look in wheel well towards the front should see the oblong reservoir with a couple of tubes connected to it.

Good thing I asked I would have never seen where the vacuum box was located. When I return home from our trip I’ll check with my local Ford dealer for a replacement box.
Thanks again for the help!

On a long hard pull, shutting off the A/C helps the engine. Leave it alone. Reduce throttle.

The vacuum tank from what I have read has a one-way check valve in it. If that is true then that would explain why my AC vents drop out under a load.

Good advice and very true. Driving a 33 ft RV with a 2,000 lb. car in a trailer up Monarch Pass in Colorado, the engine needs all the help it can get!

IMHO Engine should still have enough vacuum to operate the AC door under heavy load. I remember small inline check valves used in autos as well. Not uncommon for light vacuum hoses to crack near source near intake where it's much hotter. We use to use carb cleaner sprayed in vacuum port to wash out carbon deposits as well to find vacuum leaks as engine would stumble if sprayed on leak.
