Cooling problem

[Str8_Crazy]

Just recently my fan stopped working but my gauge seems like it's working fine. It started overheating the other day and that's when I noticed it wasn't turning on. I have been doing research and I see that there is no fan switch just a coolant temp sensor. Could the sensor be bad to where it won't turn on the fans but read the write temperature?

The cts could be bad or the fan relay.

Check the one at the bottom of the radiator. There are three sensors on the T-stat housing - one for the gauge that you see, one for the ecu, and one relating to the AC. I think the one on the radiator affects the fans.

Also when the AC is <on> both fans should run.

Only the 1g has the one under the radiator. The 2g uses the 2 wire CTS (1 wire one is dash gauge) in the thermostat housing.
