You may have a bad ignition pig tail. It is in the steering column behind the ignition switch.
The coolant fan is triggered by a temperature sensitive switch. when coolant reaches a certain temp it turns the fan on. When the coolant drops below that temp it shuts off the fan. The ignition switch plays no part in the operation of the cooling fan.
Sounds like the thermoswitch is stuck closed telling the fan to stay on. Replace the switch and / or take to a shop for further inspection.
In some vehicles the fan does stay on for alittle bit after the engine has been shut down... if it stays on for along time and wont go off then it might be the fan relay. does the fan eventually switch off by itself?if it does the fan is working corectly.it stays on till the temp is pulled back down to the temp setting.if it does not eventually shut off by it self, you need to have the fan thermostat checked
99 jeep Cherokee Laredo stay running after turn off the ignition switch?
There is a heat sensor that allows the fan to stay on after the key is off to cool down the underhood temperatures. If the fan stays on as you have said, the sensor is most likely faulty or shorted.
check your relay for the cooling fan and fuelpump
The fan is on a thermostat, causing the fan to run if cooling is required, even when the car ignition is turned off. Having said that, if you notice that the fan is running long after you've shut the engine off, you may have a problem!
The radio time would stay on if you had the keys in the ignition but the ignition was only turned halfway.
The fan remains running after the vehicle shuts off in order for the engine to cool down. Once the motor cools down sensors trigger the fan to shut it off.
If your side lights stay on when your ignition is off on a Granada Scorpio Costworth, it could indicate a wiring malfunction. You should also check the fuses.
Could be either a bad ignition switch or a bad voltage regulator (not opening circuit on shut-down)
