It is likely to be one of 2 things, the starting relay is stuck on, this can happen on an old worn relay and the contact fuse together and don't release, the other likely cause is in the ignition switch and the contact is stuck and not disengaging. You could try WD-40 on the ignition switch and if you can locate the relay try tapping it with the handle of a screwdriver or something similar, this may work temporarily but you will need to pop a new one in if it is the relay.

    I have had this problem occasionally on my 2008 when the vehicle is hot and it is over 100F outside with the AC running. Turn the key off and then starts correctly, but today burned up the alternator as well.

    There is a cube relay in the box next to the fusebox under the hoof near the battery that is often the culprit and it is too hot to handle.

SOURCE: How do you un stick

you can temporarliy "un-stick" the ignition by inserting the key as you would you start the vehicle. then tap the end of the key a few times with the palm of your hand almost as you are trying to drive it in further. this generaly works. but keep in mind that the only fix is to replace the ignition lock cylinder. and make sure that the key is not twisted or bent because that could also inhibit the key from turning properly

SOURCE: 1995 Jeep Grand Cherokee seat belt light does not go out.

Hi,
First of all, I take it you are using your seatbelt.
There is a small micro switch in the bottom of the seatbelt plug.
Check that it`s still in place. It`s only a contact breaker switch.
You could unwire it to stop the annoying light, but will need to fix it for the next MOT

SOURCE: 1994 Grand Cherokee Jeep wont start

It is likely one of your battery cables loose. Same thing just happened to me today. What you need to do is first lock the doors, and close them. Then you need to disconnect, and reconnect the battery cable, then if the security lights still blink you must use your key to unlock the door, then it should stop blinking, and start just fine.

Do you have an alarm on this? If you do, that is most likely the problem. There seems to be a problem with the alarms. You may want to have a new key made just in case. Sometimes the keys are magnetically charged and after time, it wears off.

I have a Jeep Grand Cherokee 2008, 3.7. Problem is ignition switch won’t turn off. Keeps cranking starter. The lightening bolt on dash comes up. Vehicle won’t start. Help please

I saw this problem on a 2010 chev diesel. We had to disconnect the battery. His problem was the ignition switch shorted out causing current to feed the starter . There maybe a broken connection with the switch mechanism that is not allowing the switch to change the internal selection slide.
Now if the key is stuck and not returning, then the tumblers may have come apart . This would require a new key and tumbler assembly.

Why 97 jeep grand cherokee wont start no click ?

Bad ignition switch,
Bad neutral safety switch
Bad starter relay.
Bad starter.

If you understand how relays work, you can remove the relay in the car and jump the switch pins together. If the starter motor turns the engine, you problem is the first 3. If not, its the starter itself.

My 98 jeep grand cherokee wont start. It doesnt even click or turn over. battery is fine, headlights, dome lights, all go on. Radio doesnt work with ignition on. I checked ALL the fuses, I replaced the...

fuse 8 40a supplies power to starter relay and ignition switch, to close the starter solenoid and engage the starter which draws directly from the battery. check to see that the starter relay is closing, if not ensure that the park neutral switch is not faulty (open circuit), it provides path to close relay (ground side) on the 85 - 86 terminals. if the starter relay does not close the starter will not run. if you have a spare relay swap out the relay for a quick fix attempt. hope this helps

94 jeep grand cherokee 6 cylinder

Check the starter, selinoid, and then the ignition switch if the motor will not turn over. If it turns over without fire check the ignition coil and then the distributor.
