07 LT, Radiator Fan Not Coming On.

2007 Cobalt Lt Coupe 2.2 auto

The radiator fan is not coming on.

This is my sisters car.

Here is what she says happened.

She was driving it when she noticed on the dash it said "cooling mode on" and she said the temp got up to 250.

My dad checked it out for her and told me he had it parked and idle and got it up to 235, and still nothing, the fan didn't come on. Turned the A/C on and still nothing, the fan didn't turn on. Said the connection going to the fan wasn't loose, so was hoping I could check online to see what it could be.

If it could be the fan needs to be replaced, or could it be a relay or something?

Thanks,

Relay or temp sensor most likely. Thermostat could also be bad.

Check both fuses. On way to check is to turn AC on, fan should come on immediately.

It is not turning on by itself or with the AC.
