My van began suffering from the very common problem of the vents switching while driving uphill under medium throttle. I ordered Scott’s repair kit that includes a new vacuum reservoir, and installed it in about 30 minutes. It not only solved the problems of the vents switching between defrost and dashboard, it also made a difference in the temperature of the air conditioning. I suspect that my blend door was not fully closing, allowing hot air to mix with the cold air. My air conditioning now is noticeably colder, thanks Scott it’s a great product.
 
Thanks for the very kind words! This issue is very common and pretty ridiculous with how robust the rest of the systems on these Econoline vans tend to be.

Have a look at the evaporator plastic case on the passenger side of the firewall in the engine bay. On a lot of these vans the foam seal from the case to the firewall has deteriorated and allows hot air to enter the system there. My personal van had an approximate 1" gap where the seal pulled away....I simply stuffed a rag in there to temporarily block the hot air and noticed a difference. I am trying to figure out a product that can remedy this issue more directly but for the time being this works!

The reservoir is Dorman 47076 if anyone wants one, available anywhere you can get a few feet of vacuum line.

Personally id recommend buying from Scott. His kit includes everything needed including hardware and detailed instructions on how to install all the parts. In addition, i prefer to support folks who add helpful content here.

I agree with this idea 1,000% as Scott does contribute here quite generously. :d5: :d5: :)

I agree 1000% as well. Scott and many other's here passionately contribute and support our community in many, many ways. Helping them out by supporting them in some way helps keep us all rolling and having fun. The knowledge base here is incredible. The generous sharing of knowledge, experience, skills is amazing.

The offerings we hobbyist offer are from a place of love of these rigs and helping people. It is NOT from wanting to have a business. On the other hand, we have other lives and demands, so it really helps if there is a little incentive to make/provide items that people want/need because at one point we needed it, too.

I will say from personal experience - My wife and I give a HUGE thank you and have very humble and deep appreciation for the support and acknowledgement we have received from our members and others in the van world. Without it I could not be here. Without it we would not have the wonderful, meaningful friendships and rich experience set of adventures we have been fortunate to have. It has been awesome. All from a little help-out of each other. The support of each other.

The cost of Scott's kit is super reasonable and the value add of instructions and video (which alone take crazy amounts of time to shoot and edit) are super helpful.

Yes, we are all free to buy from wherever/whomever. We are also free to make choice in how to make a difference and help each other out and give back to those that help us in some way. :d5::b5:

In just a few words Ray's thoughts elegantly express so many other's thoughts about which products and FROM whom we buy. Were I not already too well self-educated on this well known issue or HVAC venting I'd opt for Scott's kit, as mentioned having the necessary parts on hand along with a knowledge base makes the purchase price quite reasonable. :d5: One only needs to delve into the world of "hobby vendor" to completely understand the rather huge time investment required to bring something to market.

For the most part many member items for sale here are fairly ad hoc to the vehicles bringing us together here. Who better to design and fabricate things we find useful? How many here have "door claws"?? :)

Yes there's almost always a less costly option but as I've discovered waaaaaaaay too often that's rarely the best way to consider an item with we DIY's.
 
I'll be buying one of these kits to fix this problem on my own van. I found similar instructions in a service manual to basically bypass the stock reservoir and run your own. I'm curious, why does the new reservoir sit inside the vehicle instead of the engine bay?

Because room is very limited under the hood and a hose still needs to be run through the firewall in any case. Placing it in the foot well is a simple and out of the way solution that works well.
