Where is the vacuum motor on a 1995 chev suburban?

There's no single "vacuum motor" in a 1995 Chevy Suburban in the way there might be a dedicated electric vacuum pump in some vehicles. Instead, vacuum is generated by the engine's intake manifold and distributed throughout the vehicle via a system of vacuum lines and various vacuum-operated components. These components are the "motors" that use the vacuum.

Therefore, you need to specify *what* uses the vacuum you're interested in. For example, are you looking for the vacuum source for:

* The brake booster? The vacuum line for this is usually connected to a port on the intake manifold.

* The HVAC system (heater, air conditioning)? These often have vacuum actuators controlling the blend doors and vents; the source is the manifold, and the actuators are located within the HVAC system housing under the dash.

* The transfer case (if 4WD)? The vacuum actuator for the 4WD system could be under the hood, near the transfer case, or even further underneath the vehicle.

* A different system? (power locks, cruise control, etc.) Each will have its own vacuum-actuated component and associated lines.

To find the source of a vacuum leak or the location of a specific vacuum component, you'll need to consult a repair manual specific to your 1995 Chevy Suburban's engine and options (e.g., 2WD vs. 4WD). A vacuum diagram will be extremely helpful.
