Remove tailight assembly from 2003 jeep grand cheerokee

Might be a bad crank sensor.

That is the idler pulley and they do go bad and need replacing if wobbling or squeaking.

probably needs new brake pads.

Have them check your fuel filter, may be time to change- please also google the jeep to see if this is common!? Good Luck Stevo!!

Usually the plug has a tab on the back end of the plug, where the wires go in. just push/ squeeze it down and pull the plug. some timesyou have to push the plug towards the coil/sensor, then squeeze and pull.

The Grand Cherokee will have an assembly that is fastened with bolts and screws to the body.
Get the new assembly and compare to the old one to see where to unfasten the bolts and other fasteners to aid in removing quickly.

There is 2 screws located on the side when you open your tail gate by the tail light. remove these 2 screws and pull the tail light out and disconnect the wire connector. Hope this helps.

Best of luck

Most likely your thermostat is A) Stuck open, B) Has been removed, or C) Heater core has been bypassed.

There are none.

check the grund circuit....if it is weak this can happen
