What should I do if I find a leak in my vacuum?
Pinch the vacuum line leading to the device, and spray soapy water on it and hear for a change in idle speed. If you find a hose with a softened, hardened, or damaged spot, replace it. You can also spray water on a hose, ports and connectors to help you check for leaks. Using a Vacuum Gauge
How can I tell if my vacuum hose is leaking?
Purchase a vacuum gauge from your local auto parts store and hook it up to the suspect hose. Then start the car and let it idle for a few minutes. Once the car is warmed up, you can get an accurate reading on the guage. A typical care has 17 to 20 inches (43.2 to 50.8 cm) of vacuum. If your hose is reading under that, it may have a leak.
What happens if you have a vacuum sensor leak?
A MAP sensor vacuum leak can upset ignition timing and engine stability and efficiency. A vacuum leak can also prevent an EGR valve from opening, cause engine overheating, and increase harmful emissions. This type of leak can also affect the Positive Crankcase Ventilation (PCV) system.
Where does the vacuum line from the defroster go?
Vacuum lines travel from the vacuum control switch on the dash to vacuum servos under the dash. These servos move the air doors which turn on and off the defroster. If you can hear a hissing sound when the car is running from under the dash then vacuum is escaping.
What causes a defroster door to get stuck?
