Why is my Camry 4 cyl fan always running?
That requires a vacuum pump and manifold gauge set. Short of that, it’s one connector and a wrench to remove the switch. I have a 2004 Camry 4 cyl with 106,000 miles. The fans are running whenever the A/C or defrost is turned on, even when engine is cold.
What happens when you turn on the a / C in a Camry?
If you start the car and turn on the A/C, the magnetic clutch should engage and start turning the compressor pulley. If it does not, then there may be something wrong with the relay. Take the relay out and hit it a couple times. Then plug it back in.
Where is the White relay on a Toyota Camry?
Open the hood and look in the fuse box for the white relay. It should be labeled as MGCLT. Inside your engine compartment is a pulley with a magnetic clutch and the power for it goes through the white relay. If you start the car and turn on the A/C, the magnetic clutch should engage and start turning the compressor pulley.
Can a / C compressor fail on a Toyota Camry?
Although highly unlikely, it is possible for the A/C compressor to fail from general wear and tear. It’s very hard to diagnose this yourself since most other compressor problems are internal. It’s recommended that you follow Step 3 before having the compressor checked. The Toyota Camry uses R134a refrigerant as part of its cooling process.
Why does my cooling fan not turn on in my Toyota?
The Toyota’s fan only turns on when the coolant reaches a certain temperature, which is measured by a sensor. This sensor switches the cooling fan off and on as needed. A failed sensor can cause the fan to run excessively or not run when cooling is needed. The cooling fan in a Toyota has a relay to regulate when power is provided to the fan.
How is the coolant temperature of a Toyota regulated?
A Toyota’s coolant temperature is regulated by many electrical and mechanical components. One of the more important components is the cooling fan. The fan lowers the coolant temperature after the coolant has finished its cycle through the engine. A Toyota’s cooling fan is powered by an electric motor.
Is the radiator fan always running in a 2003 corolla?
As I mentioned in a few posts I had an issue with my 2003 Corolla where the radiator fan was always running with key on. Not only was the radiator fan always running, but it was running on high speed (these cars have one fan that runs at 2 speeds; low and high).
