my cooling fans are not switching on i replaced the thermostat and the switch and the sensor and my engine still over heats adn the fans dont turn on they only turn on when i put the AC on can anyone help me out what could be the problem i bleed the system and the fans still dont turn on could it be the water pump?

 

what about your fuses? did you check those, look in the engine bay for the fuse box.

 

fuses are fine

 

as far as i remember, on the h22a (non jdm variants) there are two switches - a switch A and a switch B (jdm h22a's just have a switch A) - Switch A is located in the thermostat housing (perhaps the one you replaced?) and switch B is located in the rad hose housing on the front of the engine to the left of the headers.

Switch A - only activates the FAN when the ignition switch is ON
Switch B - activates the FAN when the ignition is off.

unplug the wiring to the switch(s) and jump it (with a piece of wire or something) to see if you can get the fan to switch on - if not you most likely have a prob with the relay, or perhaps the fan itself is kaput. keep in mind - you switch A won't activate anything if you jump it while the ignition is off, but switch B should be able to activate the fan.

hope that helps - all i can remember for now

 

thanx for the info did that fans are still good got new switches still nothing i think im going to have to switch the module

 

power to the wires?

200

 

is there a sensor just for the temp guage or a module that turns on the fans if so where is the location

 

for the sensors.

the cooling fan module is next to the ecu on the passenger side. but i see some other folks answered that for you in another post...

good luck - let us know how it works out.

 

haha yea.. i realized later - this picture is from an old thread of mine, titled "official bogging and hesitation thread" - and yea you are right - jdm h22a's don't have that extra switch.

 

thanx now my car up and running woot after 2 months of just sitting thanx for the help
