cooling fan wont engage

[Ta_ser_t_s_x21]

So have been having issues with the car heating up. Changed the thermostat, but noticed that the the cooling fan will not turn on. The fans will turn on when the AC is on. Any ideas on what the deal is?

Stock fans? Aftermarket home wired in slim fans?

I'd try replacing the temp sensor/switch located on the bottom of the radiator for starters.

I can't help much, but I can give you some starters, check the relays and fuses maybe? Have you done work to the car recently? Connections?

I didnt mess with the wiring of the car, I just did a front mount kit about 2 weeks ago. And installed a new radiator, with the stock fans remounted on there.

Try the temp switch/sensor located on the bottom of the radiator. Make sure it's plugged in. If so, try swapping it with a known good. It is what tells the fan to turn on when it reaches a certain temp.

I will give that a shot
