10 HIDDEN Reasons Your Car Shakes Due To Compressor Overload When AC Is On (Engine Killers!)

Описание: Does your car vibrate or shake when you turn on the air conditioning? You're not alone! This is a common problem that can have a variety of causes. In this video, I'll break down the top 10 reasons why your car might shake with the AC on, and how to diagnose each issue.

Common Causes:
Additional Load on Engine - When you turn on the AC, the compressor puts extra strain on the engine, which can cause some shaking.
Worn Engine Mounts - Worn engine mounts can't dampen engine vibrations as effectively, leading to shaking when the AC is engaged.
Bad Idle Air Control System (Older Cars) - A clogged idle air control valve or faulty electronic throttle body can disrupt engine idle and cause shaking.
Dirty Throttle Body - Grime buildup in the throttle body can restrict airflow and lead to shaking when the AC puts extra load on the engine.
Locked AC Compressor - A seized compressor creates a significant drag on the engine, causing shaking and potentially stalling.
High or Low Refrigerant Pressure - Abnormal pressure can indicate issues like overcharging, leaks, or blockages, putting strain on the engine and causing shaking.
Clogged AC Condenser - A blocked condenser reduces airflow, making the compressor work harder and causing shaking.
Vacuum Leaks and Dirty Air Filter - Leaks or a dirty air filter can disrupt engine performance and lead to shaking when the AC is on.
Fouled Spark Plugs - Worn spark plugs can cause misfires and uneven engine operation, leading to shaking.
Clogged Fuel Injector - A clogged injector prevents proper fuel delivery, causing misfires and shaking.

Diagnosing the Problem:
Visual Inspection: Look for signs of wear on engine mounts, compressor clutch engagement, and belt condition.
Multimeter Test (Older Cars): Check the resistance of the idle air control valve.
OBD2 Scanner: Identify trouble codes related to the throttle position sensor or electronic throttle body.
Cleaning: Clean the throttle body with proper tools and cleaners.
Pressure Gauges: Test high and low-pressure sides of the AC system for abnormal readings.
Carburetor Cleaner (Leak Test): Spray around suspected leak areas to identify fluctuations in RPMs.
Spark Plug Inspection: Look for signs of fouling like carbon deposits.
Fuel Injector Inspection: Check for damage or uneven spray patterns on injector nozzles.
