    check to make sure the fan blades are turning. do you have electric fans or engine driven fans?

Sounds like one of two problems your fan is not working properly or you radiator is particularly restricted

WELL CHECK COOLANT LEVEL FIRST.TO BE ON THE SAFE SIDE REPLACE THERMOSTAT AND RADIATOR PRESSURE CAP.IF COOLANT FAN FREEWHEELS OR TURN REAL EASY WHILE ENGINE HOT IT IS FAULTY IT SHOULD HAVE SOME DRAG WHEN ENGINE IS HOT.SHOULD SPIN EASY IF ENGINE IS COLD.

2004 jeep grand cherokee laredo after driving through snow drift vibrates and is loud

I do it all the time. the reason that happens is snow packs in the rims and tires and causes the tires to be out of balance so at speed they will vibrate and make a louder road noise. solution bring it to the car wash and spray those tires down.

2004 Jeep Grand Cherokee loud grinding sound when braking

It would be hard to guess at you electrical problems but get your brakes checked.It sounds like your pads have worn down to metal on metal.Very dangerous and can get expensive to fix the longer you leave it.A visual inspection can tell within minutes if this is the problem.If this isn't the problem the 2nd most common thing is a loose brake caliper or caliper mount.A friend with some mechanical knowledge will be able to check the brake pad thickness very easily and quickly with just a torch.Hope this helps

2004 Jeep Grand Cherokee makes a loud ticking noise, won't start.

Your problem is likely a bad battery and/or corrosion on the battery terminals. Remove the cables from the battery terminals and clean them with a wire brush or other tool. NOTE: always remove the negative cable first and reconnect it last. Reconnect the cables and then try to start/jump the vehicle again. If that doesn't clear the problem, take the battery to your local auto parts store or supplier and have them check it. You will probably need a new one.

Loud whistling noise while driving.

I think there is a TSB on that problem. If the wind is coming from the passanger side then roll the window all the way down. Put a 2X4 in the door jam. So the 2X4 will be inbetween the the door and the jeep. Push on the top of the door like you are trying to close the door. What you are trying to do and slightly bend the top of the door toward the jeep. But just do it a little at a time.

2005 Jeep Grand Cherokee Problem

I would start by checking all the fuses under the hood.
There is a fuse called IOD which the factory leaves out and gets put in at the dealer.
That fuse could be bad.
