There is every possibility that there will be a problem as if the power wire to the ignition is touching the run wire (internally) then the engine keeps getting power to run and will not switch off.

91 honda accord fan stars when you shut off engine

There are two fan switches on that car;
The main one turns the fan on and off when the ignition is on and the car is running.
The second switch powers the fan if the ignition is off and the engine temperature is too high, to cool the engine off if it was just shut down.
It sounds like your main fan switch has gone bad and needs to be replaced since it's not sending any signal to the fan, while the engine is running.

I have to take the fuse out to shut off the engine

if engine does not shut off when turning key to off. its most likely the ignition switch thats bad. many people consider the switch and lock cylinder to be the complete switch. but on many vehicles it is located at the bottom of steering column. the place where you put the key is just a lock cylinder and a rod operates the ignition switch. but some vehicles have the ignition switch in behind the lock cylinder, but that depends on the make and model. first, remove the steering column cowling, look for ignition switch bolted to the underside of the column (1 x 2.5 inch box with large wires, about 8 wires going to it)
undo the two bolts and pull it away from the column.
try to operate the ignition switch manually, sliding the rod forward (start may be springed) and back, if the engine doesnt shut off when the rod is all the way back toward you, replace the switch, good-day!

Lights on dash and driving lights flicker and there is a clicking sound that does not shut off when the car is shut off wiith the key

You could have a bad ignition switch. Is your check engine light on? You need to get it scanned for codes. The computer may have picked up the problem. Autozone does the test for free. It may be more then one problem. A bad ignition switch is there, when you turn the key off, your engine remains on for a few seconds. With the lights flickering, are they dimmer then usual? If so, it could be a weak alternator.

It won't shut off

Sounds like a bad ignition switch. If you're able to turn the switch to the off postion and remove the key and the engine keeps running, the switch is bad and needs replacing. Hope this answers your question. Best of luck.

Chrokee engine will not shut when key is turned off and pulled off

there may be an open ground in the ignition circuit. i saw that once in a honda civic and the car would not shut off if anything electric was on.
you may have a bad ignition switch.
just wire a switch to the fuel pump relay and shut it off there,and it makes a good anti theft system
