i have changed the radiator switch with a new one today and it still doesnt wanna work
but the funny thing is the car never overheats when tho the radiator fan doesnt work, i took it for a drive up a mountain today and it seems fine

help

 

If you have a swapped car besure it is correctly plugged in. I can't say what it might because you have not provided any information about your car.

Kind of like saying "I got mugged by a person."

 

sorry its a dc1 integra, still has the original engine in it

it just stop working a couple of weeks ago

 

Since you changed the fan switch, My guess would be connectors somewhere. Where I couldn't be sure but start at the fan and work towards the ECU checking to make sure all the connectors are plugged in tightly.

 

untill you find the main problem.spice the green and black wire to the thermo housing together and plug it back to the thermo switch,that well keep fan runing alway's..just a temp idea

 

yeah tho the fan aint running ( i assumed its not working, cuz i cant hear it ) the car never overheats at all, even tho i stuck in traffic and stuff

i assumed the fan doesnt work because when i can run the engine for about 30min on idle and fan wont kick in at all

 

i had the same problem check the fan itself jump a wire from the battery to the fan and see if come on if it does not its the fan

 

Unplug the fan switch and jumper the terminals together. Doing this should make the fans come on if everything is working correctly.

 

well the fan itself is working BUT only when i have the a/c on
