Why is my fan not kicking on

There could be a few different things wrong here . Lets get the obvious out of the way first. Is the fan motor done . this can be checked by jumping the fan wires directly from the battery If the fan doesn run then you need to replace it ,if the fan runs then move on to the next possible solution. . Check the fan fuses and the fan relay replace if necessary If this brings no joy then check your temperature sensor . If its not working then it cant signal the fan to kick on . Hope this helps

Great answer , I just want to add that , this car usually has 2 temp sensors , one tells the computer the temp, and the other one works the gauge, light, and fan. But this was a great answer from original post.

excellent point @trnsmisonfixer , @short3sweet to check the temp sensor use a OBDII reader with live output to see if you have a temp reading from the computers sensor as this is the sensor that will activate the fan
