Honda Pilot Cooling Fan issue

I have a 2006 Pilot that has an issue with the cooling fan (driver's side fan behind radiator). When the ignition is turned off, sometimes the fan turns on (or stays on) for 30 sec to 1.5 min, then turns off. This has happened for the past 2 months. I've checked other websites, and they suggested testing the relay by exchanging with the condenser fan (same part number). I've done that and the problem still persists with the other relay. The temperature gage in the car reads normal. What else could be the cause of the persistent cooling fan?

SOURCE: Cooling fan wont work

The water temp sensor is located near the thermostat housing. This sensor is what tells the ECM to turn the fan on/off. The water temp sending unit is located near the same area. You know you have the correct sensor is because the water temp sensor has a 2 prong plug. The water temp sending unit only has 1 prong.

SOURCE: The electric radiator cooling fan will not turn off

As long as the fan eventually shuts off this isn't a problem,the fan will continue to run for a bit after the car is turned off,once it reaches a set temprature it will turn off.

SOURCE: radiator cooling fan 30 amp. fuse keep blowing

The fan may run with jumper wires but if it''s blowing the 30 Amp Maxifuse it's needs a new or used fan motor.It's pulling too many amps.I have almost never seen a fan relay concern.Only other thing you may check is the wiring down near the fan shoud I have seen the 2 wires get loose from the conduit & melt onto exhaust manifold.Hope tHis Helps

SOURCE: radiator cooling fan stays on after car is turned

It depends, how long is it staying on after you shut the car off and how hot is the temp guage when you turn it off? The fan circuit is separate from the ignition and is designed to run until the engine reads a specific temp irregardless of whether the ignition is on or not. Hope this helps.

SOURCE: 2004 Jetta GLS. Main cooling fan remains on after car turned off.

"Already had replaced: both cooling fans, fan control module, coolant temp sensor, fan switch, 4 terminal connectors. No trouble codes reported in VW electronic diagnostic test. 2 different VW dealers and and my mechanic threw in the towel. Any suggestions greatly appreciated."

This is a common problem with the VW..and no one has an answer WHY. (including VW mechanics)

THIS IS A RECALL ISSUE and should be implemented

Cooling fan switch


It is not necessary to replace the thermo-switch when replacing the radiator. The switch can be replaced separately.
The fan switch is located under the sound box of the air cleaner. It is 2 pin connector. Pull the connector out by pressing the lock which attached to it and short the two pins with a thin auto wire temporarily. Switch on the ignition. The fan will become on. Drive it and see if runs hot.
If the temp reads OK, replace the fan switch. If the problem persists, diagnose the other issues which are concerned with the overheating problems.

Why does my fan keep running in my 2003 Volvo S 60 after the car is off?


It can be faulty fan relay.The relay is not turning the system off.Or its wire short issue.Even with ignition off ,the fan relay is getting power so its not letting the fan to turn off.Bypass the fan control relay and see if still the fan works with ignition off or not.

I would have it checked for a blown head gasket. Combustion gasses in the cooling system can keep the temperature switch for the fan from operating properly.

Fan motor for cooling rear of 2003 pilot not operating


Center console need not be removed. Right side kick panel needs to be popped out, exposing the fan motor assebly. There are 3 screws securing the assembly to the duct. Remove the screws using a flathead screwdriver, unplug the unit and pull it out. The challenge will be finding a replacement motor, as they are not sold anywhere other than the dealerships (at an outrageous price)
