Question about 2003 Jeep Liberty
HI. Usually when the blower only works on a high mode, this will indicate that the resistor switch has failed. Now; In your case, there is no blower motor action at all. This is a very strong indication of motor circuit failure. The motor will be the culprit, in this case. With that said, i would advise to check the appropriate fuse/relay that is associated with the blower motor circuit. If the fuse/relay is in good condition, and it has not failed, simply, replace the blower motor. If the fuse/relay shows signs of failure, replace the fuse/relay and try to operate the blower, once again.
The fuse panel will be located on the far left side of the instrument panel(driver side). You will need to open the drivers door to see it.On the very end of the instrument panel, there should be a small plastic cover. You must pull at the bottom and the cover will release. On the back of the cover is a diagram that shows what each fuse is for. Use the little puller to remove the fuse/relay because they are inserted tightly and can be hard to pull. You will be looking for the PDC Blower Motor Relay. Test the relay to confirm the damage. If it fails the test, replace it. If it passes the test, replace the blower motor.
The relay will be numbered 24 on the panel diagram. Pull the relay an use the terminals for testing purpose.
