In cooler weather, it will take the fan a lot longer to be energized. One way to do a quick check, is to turn on the A/C. All the fan(s) should turn on with the A/C running. Some people call an engine a motor. So I am not sure if you are talking about the fan motor or the engine. If you are saying that the fan motor was checked and is good then the Thermal sensor is bad, or you have a loose or disconnected wire. The fan comes on at a predetermined temperature when it receives a siganl from the relay. you'll need to check the fan switch located on the radiator or there abouts, when you jump it the fans should come on...also make sure there is power to the switch...if theres power, and you jump it and they don't come on..its most likely the fan motor...if no power, there may be a bad relay or fuse...good luck also... everyone should have a manual for their vehicle, and a professional shop manual should be available at the library in the reference section--you can make copies of the necessary information...good luck :)
When you add engine coolant to a 2003 Jeep Grand Cherokee because the low coolant indicator has come on, you should add to the reserve tank and the radiator if they are low. Sometimes, just the reserve tank needs filled.
Yes, it is in front of the radiator. It looks like a small rad on the drivers side looking throught the grill.
Bad bearing? Leak onto engine component?
No.
When I replaced the battery on my 1994 Jeep Grand Cherokee it would not start up. I got it to work by locking all doors and then unlocking the doors. After doing this it would crank up. Hope this helps. Additional Info: Exactly. When you disconnect or change the battery the factory alarm engages and activates the engine kill switch. Just reconnect the battery and lock and unlock the doors with your key to reset it.
Possible causes include a blown fuse(s) or a failed radio.
twist back and forth and pull at same time. It should come.
It might be your TPS Sensor. They are known to go out. If you turn the key off and on five times the light will go off but after another five turns it will turn back on. Any local mechanic should be able to check it with an OBDII reader.
AC pressure transducer.
you have to remove the fan this takes a specail tool then you will drain the radiator with the plug that's on the bottom corner of the radiator next disconnect the upper and lower hoses it should come out

Have your Throttle Position Sensor Checked. Big cause of this. Do you have any check engine light come on?
take radiator cap off, make sure radiator is full, start the engine let it water circulate for awhile and then open radiator drain slightly just enough to get water and air to come out,drain is located under the radiator. Careful not to burn your hand.Turn off radiator drain and replace radiator cap.
I had this problem repaired today on my 2000 Jeep Grand Cherokee Laredo. The signs I had were: 1. Jeep was running fine, Parked it in the garage. 2. The next morning it would crank fine but would not start at all. - As my fuel was low at the time I assumed I was out of fuel but after filling it that proved not to be the problem. - In the years I have had the jeep it often takes two attempts to start the vehicle. That symptom seemed to come and go and I cannot directly attribute that to the Crank sensor problem but, it may be of use as background information.
Check the abs sensor on the rear axel first and then the sensors on the front wheels. All of the sensors are rather expensive to replace. This is pretty much a dealer fix.
On the bottom right of the radiator there should be a small square piece that is the plug. You twist it out and the coolant will come out.
