Radiator Fan Trouble
Hi everyone,
I have recently run into a little trouble with my 2002 X-Type 3.0.
The issue is that the radiator fan stays running after the car is turned off. the fan stays running until the battery is completely drained. This issue did not just start. The fan would stay on long after the car was turned off and then eventually turn off 5 or 10 minutes later. Recently, however, the fan just stays on indefinitely.
There are four possible causes that the dealership suggested:
1. Thermostat is not functioning properly
2. Electrical system has a short circuit
3. Radiator fan relay is not functioning properly
4. Radiator fan module needs replacement
Could someone please inform me as to whether any of the aforementioned causes are the source of the problem, or whether there may be another cause not listed.
******UPDATE******
I noticed that only one fan was actually running, even when the car was turned on. The other fan is not functional.
I began to take out the fuse in order to stop the operable fan.
Yesterday, when I replaced the fuse, the operable fan only ran at a very slow speed.
Next time I replaced the fuse, it would not turn on.
When I reached my destination and turned off the car, it came back on at full speed before I had a chance to take out the fuse again.
I took out the fuse, and now when I put the fuse in there is no response.
The fan has stopped running completely now. I replaced the fuse about 20 times total before the fan stopped running.
I have a few questions:

I have a few questions:
- What could be the cause of the operable fan to stop running?
- About how long will it take for my car to overheat with no fan running?
- Should I replace the entire fan assembly or just the module since only one fan SEEMS to be operable?
- Do you know if it is possible to purchase the fan module separately?
- Where would be a good place to look for a module?
- What's a reasonable price for parts and installation new module or for an entire new fan assembly?

Baltvista, look in your PM, I left you a message with a lot of these answers. I would venture to guess you fan control module is going, but that is just a guess. Do the voltage measurements I talk about in the PM and go from there. That way you are not replacing parts just because. I would hate to see you spend money on a new fan controller just to have the fans still not work.
