On my 5g prelude the fans don't come until the car is turned off. Even if the motor gets hot. I was wondering it any of you guys have a fan switch and/or another solution to the problem? thanks for the help.

 

does your car overheat?

 

it has once before and the fans still did not come on until the car was shut off

 

anymore input, please?

The fan relay <U>could</U> be taking a crap on you.

 

take this with a grain salt - because i know more about the 4th gen variant - then your 5th gen... but the usdm h22s in 4th gens had an ect switch A and B, the B switch can activate the fan after the car has been shut off - the A switch cannot. I'm <U>not</U> sure if the B switch can also activate the fan when the car is running or not - but it would make sense that it could. In any case - one of the switches (A) is in your thermostat housing, the other is in the upper rad hose outlet (B). with your car running, and switch A unplugged - try shorting it with a paperclip and see if your fan goes on. if it does - your switch A might have probs (as in a open - because all it really is, is a resistor that becomes more conductive as the heat intensifys - when your car gets hot, enough juice passes thru the switch to activate the relay to run the fan), buy a new one at honda.

swapped jdm h22a's only come with a switch A... the upper rad hose outlet is blanked and has no switch B. (info for incase you run a swap). which reminds me i still have to pick up a b switch - because i want one (;

 

thanks, more input welcome
