The radiator fan closest to my engine wont work in my 2003 kia rio, i have checked the relay and swapped the fuses over but no luck. What else could the problem be?


Hi Julie, the dual fan cooling system generally works with the larger fan being the radiator cooling fan and the smaller fan being the A/C cooling fan! If you start the vehicle and turn on the A/C and select the coldest setting within a few seconds both fans should start working!

Replaced radiator, filled it with antifreeze


Likely somebody didn't hook up the fan(s) properly when the radiator was replaced.. OR ... hopefully, this wasn't a case where the original problem with the car was the cooling fans not working.... and somebody diagnosed the problem as a clogged radiator????? I had the same problem recently with the fans not working, and the problem was a relay switch that turned on the fans when more cooling was needed.....

MY 85 STANZA FAN WONT KICK ON AND I REPLACED THE THERM AND THE RADIATOR FAN SWITCH. STILL OVERHEATING AND NOW THE A/C WONT BLOW OUT VENTD


Possibilities include blown fuse due to too much fan current draw, faulty wiring, faulty cooling fan relay, check the cooling fan relay in underhood fuse box. the contacts may be burnt and sticking.

Fans wont come on at all in my chevrolet silverado 2007 it will run hot if we are still but, if we get moving the engine cools down immediately


sounds like you have a bad temperature sensor/fan switch usaully located on the radiator. turns on fan when coolant reaches operating temperature. when moving the ram air going thru radiator is enough to cool the engine without the fan,

A/c cooling fan for my 88 mr2 non turbo wont turn


Sounds like the condensor fan relay is "sticking" - you are sure this is the condensor fan, and not the radiator cooling fan? As electric radiator cooling fans often run after the car is turned off - this is normal - If you are sure it is the condensor fan and it is on with the AC off - Id bet it was the relay responsible (versus the AC control unit) - Locate and remove the relay - if you have a comparable one you can substitue (Make 100% sure it uses the same plug and wiring schematic) and try that - if it now works properly you can try to locate one at your parts store....Hope that helps some....DD

Dodge Caravan is notorious for failure of the electronic cooling fan control module (AKA cooling fan relay). This is not a "relay", it is a solid-state control unit, but many people call it a relay anyway.
It is mounted on the inside of the left frame rail just behind the radiator. You have to look up from UNDER the vehicle to see it. It looks like the picture below. The picture shown is very close to actual size.

1998 ford mustang radiator cooing fan wont come on


Check the fluid level in the radiator - after it cools down !

It sounds like you should replace the temperature sensor that controls the fan. This is usually located in the radiator and has electrical wires connected to it. Trace the wires from the radiator fan ( not the air conditioner fan!) to the sensor.

If the radiator is aluminum you may need special anti-freeze to prevent damage.
