Why is the fan not working on my Saab?

Why is the fan not working on my Saab?

The most common reason is a burned out fan resistor. In warm weather, the fan should run briefly after engine is shut off. If the fan never comes on after the engine is shut off, the low speed circuit may not be working.

What kind of resistor does a Saab fan use?

The resistor is a cheaply made wire-wound, ceramic-insulated type, about 0.20-0.25 ohms. The resistor is not sold as a separate part by Saab, but it can be easily replaced by a generic 50-75 watt resistor of a similar value.

Where are the fan fuses on a Saab 900?

The two fan fuses (30A and 40A) are in the same location. The fan can be tested with the engine on or off (but preferrably off), by removing first the “Fan Low” relay, and putting a test lead, or a heavy wire jumper between relay socket contacts #30 and 87.

Is it OK to leave the cooling fan on when the engine is turned off?

Car Fan Still On When Engine is Turned Off You park your car, turn off the ignition and start walking away. Then you notice the engine cooling fan is still running even though the car is turned off. It is ok for the engine cooling fan to keep running for a few minutes after turning off the car.

Why is the radiator fan not working on my Saab 9-3?

Without the coolant hitting the sensor, the temp reading will be significantly lower than the actual engine temp. Your 9-3’s radiator fan will not kick on. If you do have low coolant, don’t fill it up until the engine has cooled off.

How to test the fan on a Saab 900?

Use Fuse Taps (from RadioShack etc.) or similar flat contacts in the relay socket to avoid damage to the socket. To measure the fan current, put a meter set to a 20-amp range in series with the test leads, across contacts 30 and 87. It is safer to test the fan curent with engine off:

When does the radiator fan run on low or high?

Regardless of whether the fan is cycling on low or high, the gauge will stay at 9 o’clock. The cooling fan runs on Low when the coolant temperature is over 100C, and High when over 113C.

Why is my radiator fan not working on my Toyota Camry?

If you do have low coolant, don’t fill it up until the engine has cooled off. Adding coolant to a radiator dry enough not to trigger the engine temp sensor can cause problems from drastic temperature change. Let it cool down first. Like any other clutch, a fan clutch will wear out over time.

What kind of AC system does a Saab have?

Why is the low speed fan not working on my Saab?

If the fan never comes on after the engine is shut off, the low speed circuit may not be working. If the fan resistor burns out, or if the low fan speed circuit fails for other reasons, the fan will continue to cycle on the high setting to cool the engine, but the coolant (and engine) temperature will run about 10-15 degrees C high.

What kind of engine does a Saab 900 have?
