Hi, so I am currently expirencing a problem with my radiator fan, it will randomly turn on and off intermittently after taking the key out the ignition,(only the one on the drivers side). My integra is a 1991 LS Sedan with AC. I noted the cycle of how long the fan stays on and off in between, seen on the paper. As I am new I am not really sure which direction to head first
I am curently thinking it might be one of these:
Cooling fan relay, temperature sensor, fan control timer, or the radiator fan control module.
Any help or insight would greatly be appreciated, Thank you.
Hi, Ive been trying to do more research, (Im pretty new to cars and electrical stuff) . I changed the condensor fan relay and it was still running after engine off, so its not the relay. Both fans on through the Coolant Temperature Sensor normally when the car runs so I dont belive that can be the problem(assuming both fans would turn on after engine off if it was faulty, in my case only the condensor fan turns on.) I am currently thinking it can be the a faulty oil temp switch or the radiator fan control module. I just dont know how I would check if one of these were causing the issue. Maybe I was thinking letting the car get hot and waiting for the fans to turn on then turning the engine off and dissconnecting the oil temp switch to see if the fan would stop randomly turn on. As for the radiator fan control module, I am not sure how to check if thats the issue. Also where would I get a replacement? (Sorry I am pretty new to all of this stuff) Thanks In Advance!
To my understanding, this is a feature not a bug. My 91 LS automatic with AC does this as well after driving to cool down the engine. I’ve noticed it run for seemingly a long time, but never excessively to the point it completely drains the battery.
