1999 WJ Electronic Cooling Fan Question
Hi, I have a electronic cooling fan on my Jeep as well as a mechanical fan. I have owned this Jeep for 6 months or so and have never heard the electronic fan come on. Does anyone know of a test i could do to verify that it works? I realize i could disconnect the plug and jump it to the battery but i really want to know if the sensor that tells it to come on is working. It's been super hot in my area lately and I'm concerned about overheating. I just put a radiator in it a few weeks ago cuz it sprang a leak and i'm thinking because that fan isn't working it could pop this one too...Any input will be helpful..Thanks

Well I did Confirm that the fan does work. Does not come on with ac on until temp gets to 210. It does not remain on when the vehicle is turned off like some other vehicles i have had did, however those vehicles did not have a mechanical fan also. Should it keep running with the vehicle off?
