SOURCE: how to replace rear brake pads on 2005 jeep liberty

put the back of car on jack stands and secure the front tires so it does not roll and then remove the bolts off the back of the caliper there is normally two one at top and one at bottom and spray it with some kind of oil for rust and make sure you have the right size socket before you try to loosen them and once caliper is off and the old pads removed take one of the old pads and squeeze the piston on the caliper back in by using a "C" clamp and also remove some of the brake fluid from the master cylinder before you do this put the new ones back on and check the brake fluid and make sure it is full and then pump the brakes to make sure you have a good pedal also put some "No Squeak" brake stop on the back of the pads so they don't squeak they will have that where you buy the pads from

2005 Jeep Liberty will not start no click no noise rather new battery. starts with jump but will not turn off even removed the key. replaced the power relay. still no start. newer battery.


Did you check the starter motor relay , location , under hood power distribution center ? When you turn the key to start the ignition switch sends a 12 volt input to the PCM / ECM - engine computer . The engine computer will then energize the starter motor relay . This is all computer controlled . Hooking up a scan tool to check for DTC'S - diagnostic trouble codes an viewing input data should be the first in diagnosing a problem like this .

How to wire a relay.


A relay is used when the load you want to switch draws more current than the switch available for the application. For instance, you want to install auxilliary/spot lights on your off road vehicle. The ignition switch may not be able to cope with the additional 15 or 20 Amps required. Enter the relay. It uses a small current to supply a large amount of power from the battery to where you need it.
On the bottom of the relay are numbers stamped next to the connecting tabs, they are wired as follows:
  • 30 - Connected to positive of the power source(battery). Put a fuse in line with this as close to the power source as possible.
  • 87 - Connected to load. This would be whatever you want to power ie fan, lights, electrical motor etc. The other side of the load is connected to earth(negative of the power source)
  • 87a - Anything connected to pin 30 is routed inside the relay to thispin when the relay is off. When the relay is switched on, this pin isdisconnected internally from 30.
  • 85 and 86 These pins are used to switch the relay. 85 isusually connected to earth. 86 is then connected to the activation switch and the otherside of the switch is then connected to your power source. (It does not matter which way round you connect these pins polarity wise, since between these 2 pins is a coil used to pull in the contact points and as long as they have power across them, the coil will activate.)
Below is a typical application. In this case to power a radiator fan.When wired as below the fan will work only with the ignition switchedon and the radiator hot. (Thermo switch - v - activated) This is not only suitable to Jeep but Dodge, Volkswagen, Ford, Chrysler, any vehicle as long as you keep to the basic configuration.
Let's get some air over that cooling system. Referring to the diagram:
  • i is the battery
  • ii is a suitable fuse(see below)
  • iii is a suitable switch or in this case the vehicle's ignition switch.
  • iv is the relay (Beware, there are different relay pinout configurations but the numbers stay the same)
  • v is the load (In this case the radiator fan)
  • vi is a thermostatic switch mounted on the radiator
When purchasing make sure firstly that the wire used is of the correct guage(thickness/current rating) for the given application. You dont want the wire melting because it is too thin and cannot handle the current. Find out how many amps the load will draw and add at least another 20% for reserve. The fuse rating should then be matched to the wire's capability since it prevents the wire and power supply (battery) from overload and fire.
If you wanted to wire your headlamps by this circuit, iii would be the high beam switch. The headlamp "on" switch should be wired between fuse ii and relay pin 30. Low beam is connected to pin 87A and high beam to pin 87 instead of the fan. The thermo switch would of course not be needed and can be replaced with a wire straight from pin 85 to earth.

I have a 2002 jeep liberty kj 3.7L and the fuel pump relay clicking slowly but constantly with ignition in off position? Relay already replaced, so not that. Ideas?


Are you sure that it is in fact the fuel pump relay ? With the key off no B+ voltage is supplied to the relay . Pin 86 at the base ,where the relay plugs into . Fuse #15 a 10 amp fuse is hot with ignition switch in the run or start position . Pin 85 is control from the PCM - engine computer . Pin's 30 & 87 are the load side , fuel pump being the load . If your unfamiliar with the pins i'm talking about , pull the relay out an look on the bottom ,you will see these numbers .Pin #30 will show B+ voltage all the time , pin 86 only with the key on or start .

How do i check the window switch jeep liberty?


Get yourself a test light and remove the switch from the door panel, you should have 12v going to one side of the switch and when you activate the switch power should be available at the other side. If you remove the door panel and access the wires going to the window motor, you should get power to the motor when you activate the switch. If you have power going to the motor and the motor doesn't run.....has top be a bad motor.

2005 Jeep Liberty, does not re- start, does not crank, no solenoid click.


From your description it seems as if the relay is bad or else the battery is shorting out inside and needs to be replaced. I would change the relay to start.

My 2005 jeep liberty will not start. Starter is good. What could be the probable cause?


Check the battery for bad connections..take off the cables and clean both the battery posts and the cable connectors and then try...if no start, then see if you can check the battery voltage with a voltmeter...at stand still(engine not running) the battery should read 12.5 volts...if battery is ok, then there is the possibility that the starter solenoid, the starter relay, or (in rare cases) the ignition switch is bad

Check that you have power at the main post of the starter. Then check the solenoid activation circuit from the ignition switch.

I need a negative lock/unlock relay for a 2003


i don't have a wireing diagram for you but all relays use power to pin 86 or 85 and ground to pin 86 or 85 does't matter as they just energize a coil in the relay.pin 30 is either a power or a ground depending what you want switched.when the relay is activeated pin 87 becomes the same as pin 30.pin 87a is rarely used but it will be the same as pin 30 only when the relay is not activated.hope this helps.

Front Window stoped working on 2002 Jeep Liberty


Three things. Fuse, window motor, or bad switch. If the fuse is good, remove the door panel, disconnect the harness to the window motor, and check to see if you have power with a test light/volt meter while pushing the window switch (ignition switch in ON position). If you have power, the motor is bad, if you do not, replace the window switch.
