Vacuum pump under front

Hya all, especially to night hawk and old English, my vacuum pump has broken off its mountains but I can't think for the life of me where it was attached to, if could possibly take a photo of there's and send it to me so I can see exactly how it is attached and where too, also can someone remind me what is the purpose of this, I did ask the question sutch a long time ago Ive forgotten, I think it's something to do with air vents, I've noticed there is a fuse under dash for this, does it operate by a switch or does come on automatically when engine is running thanks kev

It operates the AC/heater vents and goes into action when the Ford heater controls are moved. In your coach, the slider may be damaged so you need to make a plastic/wood/etc stop so the slider reaches it's limit about a quarter inch from the left stop. Otherwise, it will run all the time and suffer an early demise. Open the driver's side access door and look in. The pump is mounted on the wood bulkhead and should have screw marks where it came off. I will try and find a photo.
