Hi,
There are two basic sensors that feed information to the computer, which in turn controls three relays that control the fan speeds. The two sensors are:
- Engine Coolant Temperature sensor
- AC Refrigerant Pressure sensor
Based on these inputs, the fans are either OFF, LOW SPEED, or HIGH SPEED.
I have provided a link that gives more details about the system
Good Luck, Greg

Where is the relay switch for the raditor fans in a 99 Chevy Venture?
The cooling fan relays, there are three, are located in the fuse box under the hood above the battery.
What would cause the radiator cooling fans to work when the engine is off on a 2000 Chevy venture?
Hi, If the cooling fans run for a few minutes after turning off the engine and then stop, the engine computer probably thinks that the coolant temperature is very high and is trying to cool that off. If the fans run on and on and do not stop at all, then I would say that you have a shorted control relay for the fans. So a little troubleshooting is needed for this issue. I have provided a link that describes how these fans are supposed to work and how they are controlled. Good Luck, Greg
What would cause the radiator cooling fans not to work on a 2001 Chevy venture?
Blown fuse? Bad relay? Bad temperature sensor Bad fan motors? Check to see if the fans are getting power if so motor is bad If not check the above
After replacement of coolant temp sensor on 97 Chevy venture fans don't come on?
You will have to do a little troubleshooting to find out what the real issue is here. A scan tool that can read the coolant temperature may help, as it will show you what the engine computer is reading from the sensor. This is important because the computer controls the cooling fans through 3 relays, so that they turn on at the appropriate time. But if you see the temperature gauge changing once the engine starts to warm up, then the temperature sensor is probably working, as the computer also controls that gauge. I have provided a link that gives more details about the engine cooling fans and how they should work. Good Luck, Greg
Why does your Radiator fan not turn on rover mg?
Usually ECT or engine coolant temp sensor. That's what tells the engine computer to turn on the fans.
Where are the fuses for the radiator fans 1998 Chevy venture?
Hi,The fuses for the radiator fans are located in the Under-hood fuse block, which is located just above the battery. I believe there are actually two fuses: COOL FAN 1 & COOL FAN 2. You can see a diagram on the link provided.Good Luck, Greg

Where is the fuse box for the radiator fan?
If you are referring to a late-model Chevy Venture (or similar Chevy), the relays (there is more than one) that control the fans are located in the under hood fuse box. I have included a link to one such fuse box, which has pictures and diagrams of the fuses and relays inside. Good Luck!
Chevy venture low side ac service port location?
Low side service port is just behind the condenser and radiator fans and just in front of the front exhaust manifold. It is a booger to get things hooked on when the engine is hot! Be careful.
