weird issue here, cant really think of any solution.

i've got my fan controller wired up to the switched 12v source coming off of the window washer pump.

anyways when im driving , and this only really happpens during the day when its hot outside, the fans just turn off. but when i turn the car off when this happens and put the key to the 'on' position the fans turn on. i start the car again and the fans turn off.

i looked at the voltage going through the 12v wire going to the fan controller with a multimeter and when its acting up i dont get more then 5 volts...

but when everything is working fine i get a voltage reading of 12.2 volts when the car is off and 14v when the car is on.


any thoughts guys ??

thanks.

Is it possible anything is slightly shorting to ground, or you are using a relay or something that doesn't like the heat?

What fan controller are you using, are you using relays to turn your fans on through a fan controller ?

yeah the fan controller has an integrated relay.

its a really cheap fan controller that i got here. i dont even know what the name of it is.


there are no shorts.

the relay might be cheap and over heating like someone above stated.

I'd suspect the fan controller being screwed up by the heat.

yeah i thought it would be the relay as well

thanks alot for the input guys.
