6. Bad Electrical Connection Of AC Clutch Coil
AC clutch coil uses 12v current from the battery to get magnetized and pull the clutch plate towards the magnetic pulley.
In electrical connections, there can be intermittent electrical faults due to damaged insulation, exposure of wire and connector to moisture, and loose connections due to damaged harness connector. So, due to these intermittent faults, the AC compressor starts cycling after 3 to 4 seconds.
To test for a short-to-ground compressor coil circuit, set a digital multimeter to the ohms scale and touch one lead to a clutch coil terminal and the other to a ground point on the compressor.
If there is a short circuit, you will not see any conductance. Similarly, perform the test for the other terminal of the coil.
After that, check the resistance across the terminals of the compressor clutch coil. If the resistance is less than 3 ohms or more than 5 ohms, it means the coil is bad.
Does Throttle Body Affect AC?
The question of whether a throttle body affects car AC is one that can be answered with a resounding “No” – but it’s a bit more complicated than that. The throttle body is an important part of the engine’s air intake system. It controls the amount of air that enters the engine, which is then mixed with fuel and burned in the cylinders to create the power that turns the wheels. If the throttle body isn’t working properly, it can cause the engine to run rough, which reduces performance and fuel efficiency. When the engine is running rough, the car’s AC system puts strain on the engine due to the increased demand for power. This can reduce the cooling power of the air conditioning system, making it less effective at cooling the cabin.
