Window out of the track on a 2004 jeep gc - 2004 Jeep Grand Cherokee

SOURCE: 2004 Jeep GC limited stalls ONLY in reverse

you have to be careful that it is not the safety neutral switch.since stall means different things to different people,it is hard to tell exactly what is the issue.if the safety neutral switch,which is wired to the start and ignition circuits is bad,it could kill the engine.
jack up the vehicle and look for bad or shorted wires or connectors before doing anything else.
the other thing is how it behaves with no load on it. put a floor jack under the rear differential and raise it just enough for the wheels to be off the ground a couple inches.put it into reverse with no load and see if the wheels turn in 2wd mode.

Grand Cherokee oxygen sensor locations for 4.0 and 4.7 engines







Four wires (circuits) are used on each O2 sensor:

• 12–volt feed circuit for the sensor heating element
• Ground circuit for the heater element
• Low-noise sensor return circuit to the PCM
• Input circuit from the sensor back to the PCM to detect sensor operation

O2S Sensor removal Never apply any type of grease to the oxygen sensor electrical connector, or attempt any soldering of the sensor wiring harness.
WARNING: THE EXHAUST MANIFOLD, EXHAUST PIPES AND CATALYTIC CONVERTER(S) BECOME VERY HOT DURING ENGINE OPERATION. ALLOW ENGINE TO COOL BEFORE REMOVING OXYGEN SENSOR.
1. Raise and support vehicle.
2. Disconnect O2S pigtail harness from main wiring harness.
3. If equipped, disconnect sensor wire harness mounting clips from engine or body.
CAUTION: When disconnecting sensor electrical connector, do not pull directly on wire going into sensor.
4. Remove O2S sensor with an oxygen sensor removal and installation tool.

02S Sensor installation
Threads of new oxygen sensors are factory coated with anti-seize compound to aid in removal. DO NOT add any additional anti-seize compound to threads of a new oxygen sensor.
1. Install O2S sensor. Tighten to 22 ft. lbs. (30 N·m) torque.
2. Connect O2S sensor wire connector to main wiring harness.
3. If equipped, connect sensor wire harness mounting clips to engine or body. When Equipped: The O2S pigtail harness must be clipped and/or bolted back to their original positions on engine or body to prevent mechanical damage to wiring.
