Vacuum

What are the basic and essential tools needed to diagnose and repair the vac system{s} of my sig car.
I keep finding plugged vac hoses and fittings; one in the trunk up in the rt rear fenderwell, another in the upper trunk sill near the trunk latch. Are there some optional components that I may not have?
I have not experienced any obvious problems with the car but I am not sure what all is operated by vac.
Power windows work elec or vac?
Power ant? looks like an aftermarket electric unit.
I have Manual trunk lock and manual door locks. should they be power?
Haven't used climate controls. Round knobs on upper console/dash area; Driver side rotates, pass side stuck. Not used much, seized?
Florida car so not much heat needed , even less on the pass side
AC belt off comp and pressure switch underhood is out and deadheaded
Trans lightly kalunks into gear but seems to shift ok no obvious slipping
What have I missed beyond the underhood connections and components
I need to learn this if I want to keep this car.
Andrew

Try looking above for vac diagrams, they will help you out. So will we, of course.

I pulled the console apart today to have alook at the wiring to the radio and cig light: all messed up PO cut and spliced in new radio and such but thats another story.
I pulled out the pass side climate control to have a look at it since it is stuck. The unit seems to be sealed. Where would the underhood valve be located?

I prefer my all metal version made by ACTRON bought at Pepboys auto parts 20 years ago and there are also China/Taiwan made copies.
A regular automotive type Vacuum Gauge can be used to test the pump and stuff but the Mity Vac types have a hand pump that allows you to create the vacuum.

Don't believe everything in my previous post.. I can't believe I told you windows were vac. Sheesh.. They are definitely power. I believe the valve is on the firewall, sitting horizontally. Not real familiar with the manual setup.

Found the heater valve and was able to remove it and free up the control cable with a little loosejuice and some back and forth moving. Thanks
