SOLVED: Volvo Cooling sensor / fan arent working - Fixya

Since your temp gauge is working that means your coolant sensor is working ... which is good. If the sensor goes bad that can affect what the car computer tells the fan to do (but most cars default to fan on if the sensor goes belly up). So that leaves the fan relay .... usually under the hood somewhere ... but I am not familiar with this Volvo ...

1993 Ford Escort engine. Radiator fan not working ...

Radiator fan not working unless the temperature thermo switch is unplugged and the circuit is open. If plugged into the thermo switch it never runs the fan even when the engine warms up.

Replaced the temperature switch and still doesn't work. I ...

Radiator Fan Only Works When Temperature Sensor Unplugged

· Same exact issue. Fan only works when the A/C is on. Checked the fuses/relays, all good. When I turn the A/C on, the fan comes on intermittently which make me think the engine coolant temperature sensor is working properly (as temperature goes over 209 degrees it triggers the fan to come one). Not sure why it wont work when the A/C is not on. I bought a new sensor ($) then I found this thread and it seems replacing the sensor …

Cooling fan temp switch | LS1LT1 Forum

· Ok, so the problem I found was with the calibration between the coolant temperature sensors. The sensor for the gauge (in drivers side head) is consistently reading 25-30*F higher than the sensor for the cpu (near the water pump). Both sensors are new so I am not sure why there is such a difference between them. I ended up editing the fan turn on temperature to 200*F for low speed and …
