I need to find the location of the cooling fan relay in my 2002 Honda civic EX?

Is the relay getting power, and can you jumper it to make the fan come on ?

if its an overheating problem the cooling fans may not be coming on.this needs to be checked.it could also be a bad temperature sensor for the computer and its getting the wrong temp reading,thus not turning on the fans.there is also a cooling fan relay(not a problem that happens often).one other thing the impellers on the water pump may be worn out or not turning with the pump shaft.

Yes there is a sensor and a fuse and a relay....You must frist check power at the fan...Red wire...when engine is hot

Hi:
I am reasonably sure that your horn relay is in the relay/ fuse box that is located beside your battery, on the rear passenger side , under the hood!

with your description it sounds like your fans are not coming on, also sounds like the problem was never solved, sounds like you threw a lot of money at your problem also... check to see if the fans are coming on at the right times, seems like a n air movement over the radiator since you say it only gets hot in stop and go traffic... well when your driving at a constant highway speed guess what you have air movement through the radiator... check also a clogged ac condensor with bugs, pressure wash it out so the air can pass through it easily... please rate my help thanks

check the temperature switch for power and test power at fan relay, you can also run wire from battery to fan directly and tap to see if fan works

I have a 2002 Honda Civic Ex, it has been over heating but only in stop and go traffic, never on the freeway, i have replaced, timing belt, water pump, cooling fan relay, cooling fan switch, flushed radiator. There is no white smoke coming from the tail pipe and the oil is clean, when the car gets hot i can smell the coolant pretty strong, car has never completly overheated gets about 3/4 of the way til red.

you mean the cooling fan? for the rad the relay is under the hood by the battery in the fuse and relay box
