Hey there guys,

My Ks verada has been getting quite warm quite fast. I am trying to find out why the thermo fans are not kicking in. Now This is what I have replaced.

The Thermo Fan (passenger side fan) Tested and Works
Thermo fan temp switch. (bottom of the radiator
Checked all relays and tested,
Bought a second hand coolant temp switch.

I am stuck! I dont know why it is still overheating, When I switch the air con on the thermo runs. When I dont have that no matter how hot it gets the thermo's don't kick in!

Ideas anyone?

Thanks a lot

oh god stuck with similar problem. fans are not kicking(but manually fans are working fine when connected directly to battery). fuses and relays are fine. but i couldnt able to locate the thermal switch. And im getting boiling water sound in ac vents when releasing gas on drive. please help me sorting out this.

Could be a dead thermo fan on the drivers side, try run a test +12Volt cable to your drivers side thermo and see if it spin.

The left hand one active with the AC on.

Thermo switch is located in the bottom of the radiator. Unplug the connector, use a paperclip to connect the two connections in the plug, turn the ignition on. The fan should run if the thermo switch is defective. If the fan doesn't run check fuses and relays.
Gurgling in AC vents is probably air bubbles moving through the heater core.
