2006 Jeep Liberty Shifter CablesWhen I put my 2006 Jeep Liberty shifter in park I cannot get the key out. I also noticed that I can move the shift from park to reverse without pushing the safety button on the shift. Is this a linkage, computer, or transmission issue.


  1. Shifter
  2. Gearshift Cable
  3. Park-interlock Cable
  4. Shift Cable Seal Plate
  5. Floor Pan

RESPONSE

The cable from shifter to ignition broken would cause the key issue. Broken shifter internal parts may be the cause for the ability to shift without pushing button. It appears to be a common problem for the 2004-2006 Jeep Liberty.

Requires replacement of entire center console 2006 Jeep Liberty shifter assembly with an “upgraded/improved” mopar part to fix the known high failure sub assembly (but not available for purchase separately).

RESPONSE

Only know of the AX15, AX5 and the 30RH that came in it.

INSTALLATION METHODS AND PARTS USAGE

Distortion of clutch components during installation and the use of non-standard components are common causes of clutch malfunction.

Improper clutch cover bolt tightening can distort the cover. The usual result is clutch grab, chatter and rapid wear.

An improperly seated flywheel and/or clutch housing are additional causes of clutch failure. Improper seating will produce misalignment and additional clutch problems.

The use of non-standard or low quality parts will also lead to problems and wear. Only use recommended factory parts.

A cocked pilot bearing is another cause of clutch noise, drag, hard shifting, and rapid bearing wear. Always use an alignment tool to install a new bearing. This practice helps avoid cocking the bearing during installation.

2001 Jeep Grand CherokeeI put a new brake reservoir on my 2001 Jeep Grand Cherokee 4.0 L. I filled it up with brake fluid and then I pumped until I had a pedal but once I started the truck then I had no more pedal? Any answers?


RESPONSE

You still have air in the system. You will need to bleed the brakes. Have your assistant hold the brake pedal down, then open the bleeder fitting. Close the fitting before releasing the brake pedal.

How to Brake Bleeding

  • Clean the master cylinder of excess dirt and remove the cylinder cover and the diaphragm.
  • Fill the master cylinder to the proper level. Check the fluid level periodically during the brake bleeding process and replenish it as necessary. Do not allow the master cylinder to run dry, or you will have to start over.
  • Before opening any of the bleeder screws, you may want to give each one a shot of penetrating solvent. This reduces the possibility of breakage when they are unscrewed.
  • Attach a length of vinyl hose to the bleeder screw of the brake to be bled. Insert the other end of the hose into a clear jar half full of clean brake fluid, so that the end of the hose is beneath the level of fluid. The correct sequence for bleeding is to work from the brake farthest from the master cylinder to the one closest; right rear, left rear, right front, left front.
  • Depress and release the brake pedal three or four times to exhaust any residual vacuum.
  • Have an assistant push down on the brake pedal and hold it down. Open the bleeder valve slightly. As the pedal reaches the end of its travel, close the bleeder screw and release the brake pedal. Repeat this process until no air bubbles are visible in the expelled fluid.
  • NOTE: Make sure your assistant presses the brake pedal to the floor slowly. Pressing too fast will cause air bubbles to form in the fluid.
  • Repeat this procedure at each of the brakes. Remember to check the master cylinder level occasionally. Use only fresh fluid to refill the master cylinder, not the stuff bled from the system.
  • When the bleeding process is complete, refill the master cylinder, install its cover and diaphragm, and discard the fluid bled from the brake system.

2002 Jeep Grand CherokeeMy 2002 Jeep Grand Cherokee with a 4.7L engine is over heating, I don’t think my coolant is going through my motor??? The air never gets warm it stays cold. I’ve changed out the water pump and thermostat, no change.


RESPONSE

The most common reason would be form being low on coolant that may be from not bleeding the cooling system properly. Locate the cooling system bleed plug. Failure to purge air from the cooling system can result in an overheating condition and severe engine damage.

Cooling System Bleed Plug – Bleeding

  1. Tighten the radiator draincock and the cylinder drain plugs if removed.
  2. Remove the cooling system bleed plug from the upper radiator hose inlet housing (see Fig. 1)
  3. Fill cooling system with 50/50 mixture of coolant and low mineral water content until coolant begins coming out of the cooling system bleed hole. Install the cooling system bleed plug. Fill radiator to top and install radiator cap. Add sufficient coolant to the overflow tank till it reaches the FULL mark.
  4. With the heater control unit in the HEAT position, operate the engine with radiator cap in place. After engine has reached normal operating temperature, shut engine off and allow to cool. When engine is cooling down, coolant will be drawn into the radiator from the overflow tank.
  5. Add coolant to the overflow tank as needed. Only add coolant to the overflow tank when the engine is cold. Coolant level will be higher when the engine is warm due to thermal expansion. To purge the cooling system of all air, this heat up/cool down cycle (adding coolant to cold engine) must be repeated three times. Add necessary coolant to raise tank level to the FULL mark after each cool down period.

The engine overheating may be from being low on coolant and if it is not, It may be from the cooling fans not coming on if electronic or failed clutch fan assembly. As for warm air not coming out the dash, it may be caused by a clogged heater core or an issue with the ventilation system such as a failing blend door actuator. Failed Actuators are common on Chrysler products.

The blend door for all models is actuated by an electric actuator, while the AZC system uses 2 separate actuators to allow the driver and passenger to select individual comfort levels.

The mode door actuators for vehicles equipped with the standard equipment manual temperature control system are vacuum controlled. The optional Automatic Zone Control (AZC) system uses electric motors to actuate all mode doors. The service procedures for both types of actuators are covered by the following procedures.

Gas tank was replaced today, but car doesn’t start or run like it used to. Should I allow time for engine to adjust or should it not matter? My car almost stopped in the middle of traffic on half a tank of gas in it. I paid $500 to get the gas tank replaced but I feel cheated. Should I be worried ?

While driving my jeep it will jump out of gear, do not know if its shifting into in overdrive of not. I have to pull over and work the 4wheel gear in order for the manual drive to engage any idea what might be causing this.
Thanks,
Linda

Working on friends jeep she had battery light come on and started heading home about 30min 25miles later overheated and stalled.. i went the next day and pulley was loose replaced water pump and coolant started car and it was jerking running rough.     Pulled codes p0300(multiple misfire) P0700(transmission control module malfunction) and p0562 (system voltage low).   I replaced the spark plugs and battery still ran rough at idle but ok going down the street almost stalls between drive and reverse and at stops.  only took out to refresh codes since battery disconnect.   New codes are P2305(cylinder2 misfire) p2311 (coil 2nd circuit number4 cylinder) and p0123(TPS detects high volts…   now i had pulled all the coils once and,checked the tps when i was diagnosing looking for any heat damage and also to see which coils were not affecting when unplugged.   I cleared codes and all im getting now is p0175 p0173 which is rich exhaust detected by o2 sensors but the three it just showed weren’t there anymore… now she ordered 2 coils and a TPS and went to a mechanic who tells her its blown up wont be specific at all he claims its got no oil in it however i checked the levels and they were fine before i left it parked there without TPS or the two bad coils in it so she couldn’t drive it how could it be blown also how could it not be blown because I’m no certified mechanic but i know a lot and i didn’t think it was blown up beyond repair it was still starting, and idling before i removed those parts..? Suggestions opinions help?!?!
