the only problem that vehicle has is with cooling fans is relay/module or electrical harness to module that burns up located behind and under right front headlamp assy must remove headlamp to access relay/module that is what powers up fan motor module assy.

SOURCE: CAN YOU TELL ME HOW TO USE A SLIM JIM TO UNLOCK JEEP GRAND CHEROKEE LAREDO. LOCKED KEYS IN CAR.

a slim jim is not a good ideal to be using in todays cars and trucks with airbags everywhere and wires inside doors..call a pro and if he pulls out a slim jim send him packin...there a re far better tools to use than a slim jim

SOURCE: I have 2001 Jeep Grand Cherokee Laredo and it is leaking coolant

Front drivers side could be a bad cap, lower hose or the radiator itself. You need to look carefully and find the leak source. Steam travels and isn't a good indication of where the actual leak is coolant will run down and take any path it can to reach the ground. Therefore, you need to follow it back to where it is coming from, then deal with it. Your water pump can also leak and run down the lower hose. there is a small hole in the pump behind the pulley. If you see coolant coming from there the pump needs to be replaced. Sealers will not work on hoses or pump leaks so don't bother using them for that.
Good luck...don't forget this is free, so rate answers!
I will answer follow-up questions too!

SOURCE: i have code p0137 coming up on my 2003 jeep grand

P0137 - Oxygen O2 Sensor Circuit Low Voltage (Bank 1, Sensor 2)

Essentially the same as P0136, P0137 refers to the second oxygen sensor on Bank 1. P0137 means the O2 oxygen sensor's voltage remained low for longer than 2 minutes. This, is interpreted by the ECM as a low voltage condition and sets the MIL. Bank 1 Sensor 2 is located to the rear of the catalytic converter and should produce an output signal relative to oxygen storage capacity of the catalytic converter. This rear (sensor 2) sensor is less active than the signal produced by the front sensor. However, if the ECM senses the sensor is inactive, this code will set.

Symptoms: There may be no visible symptoms to the driver, other than the MIL (Check Engine / Service Engine Soon) illumination.

Causes: A code P0137 may mean that one or more of the following has happened:
* Faulty o2 sensor Exhaust leak near the rear sensor
* Plugged catalyst
* Short to voltage on O2 signal circuit
* High resistance or open on O2 signal circuit

Possible Solutions:
* Replace faulty sensor
* Repair exhaust leak near the rear sensor
* Check for restriction in catalyst and replace as necessary
* Repair short, open, or high resistance on o2 signal circuit
