Default 1995 accord lx radiator fans

Yes my question is and of course MY PROBLEM is 'Why does my a/c fan turn on right after i turn off my car? Even with 5 seconds of just leaving it on that fan turns on and will stay on for who knows. Its on for so long I have to un plug the battery. Let me not forget to say last december it was in a collision which didnt wreck the car but I did have to replace the radiatorr, power steering, the fans were from the junkyard and of course the body work was replaced as well. Back to the topic... I did check the fuse box and they were all good. Havnt ran the car since December except a couple times I just took it for a test drive. And let me addd. THE CAR DOES NOT HEAT UP Thanks in advance

If the coolant temperature is above approximately 223 degrees F at the Engine Coolant Temperature (ECT) Switch B (located on the coolant outlet housing connected to the upper radiator hose) after the car is shut off, the radiator fan will run for about 15 minutes.

If it runs for more than 15 minutes, the radiator fan control module (located behind the glove box) is probably faulty.

So starting with a cold engine, you start the engine & let it run for only a few seconds then turn it off... the fan runs??

Temperature switch on the nozzle for the upper radiator hose, at the head. Look for messed-up wiring. If something pinched those wires together, anywhere in the wiring harness, that would explain the problem.

Unplug that temperature-switch & try the process again. If the fan DOESN'T run now, then it would be a faulty switch.

If the fan still runs, then you can look at the fan-timer module. I think it's somewhere in the passenger-side dashboard. You'll also want to check whether the wires to that switch are shorted to one another.

So my passenger fan 'a/c fan' stays running even if I dont turn on the car. If I go to the 'two lines' on the key before starting the ignition and turn the key back as if I am going to remove the keys then he fan goes on as well. Im not much of a knowledgable person on cars (wish I was) but im trying. I apreciate everyones help thanks a mill.

How can I check if the driver side fan even works? Because ever since I replaced it I have not seen it run at all

Since the airbags have gone off, can that affect the module since it is behind the glove box?

1. The driver's side fan is considered the A/C condenser fan.

If the A/C system is functional properly, when you turn on the A/C; both radiator fan and A/C condenser fan should run at the same time.

Since that doesn't sound like the case, you can disconnect the ECT fan switch A (located on the thermostat housing near the back of the engine; see picture) and jump the connector with a wire or small paper clip. With the ignition ON, both fans should run at the same time. The ECT Switch A, if functioning properly should also turn on both fans if the engine coolant temperature at the switch is about 199 degrees F or above with the engine running.

If the A/C condenser fan doesn't run, then try the next test.

2. The A/C condenser fan's electrical connector is up top. (See picture) You can disconnect the 2P connector and apply direct battery power (+) and ground (-) with wires (such as speaker wires) to see if the motor is good. If the motor is good, then there is an issue somewhere in the circuit.

The front passenger air bag and the radiator fan control module are on separate circuits; so, normally one will not affect the other.

Unless the mechanical shock of the passenger-side airbag has done something to the fan timer module??
