A/C vacuum actuator motors

(07-13-2018, 06:46 PM)Don C Wrote: Section 36-32 of the Ford Shop Manual describes how it all works and has good illustrations. The control knob actuates the various vacuum motors, shuts off the hot water, and turns the a/c compressor on. All it takes is failure of one item, like a leaking vacuum hose or blown fuse to keep it from functioning.

Great imput Don.
How well do the vacuum motors stand the test of time? Are they reliable or do they have a finite lifetime of work?
I am tempted getting my vacuum motors tested to see if they are still working. As i stated before i only want to do my A/C once so don't want to re-install vacuum motors if theres a chance they will fail in future

If they are original I would say they have outlived their useful life span by many years. Due to the time involved in removing and installing a heater-a/c box I would replace or rebuild everything, including the blower motor.

The way I look at these things is what is the value of my time times how long it will take, and then compare it to the out-of-pocket expenses of doing the right thing.

Didnt even consider stripping the blower motor. Good call. Is there any particular part i need to focus on Don?

You can test the vacuum accuators with a brake bleeder/vacuum pump. All but my dual diagram motor worked. To save a few bucks I decided to replace the ones that were hard to get to with the airbox installed. A few are easy to get to later. So far no problems with the old ones.

For the blower motor, the brushes and clean and grease the bushings. The brushes are usually the first to wear out, I don't know if it would be possible to find replacements, maybe an automotive electrical repair shop.

There many types of brushes on amazon and eBay. If not there then try http://store.eurtonelectric.com/brushes.aspx. They have just about every type of motor brush.
