I have a 2005 Jeep Liberty. The keyless remote unlocks the doors reliably, but locking only works every 5-20 attempts. It does this with both FOBs. I suspect a problem in the receiver or a relay. Can someone point me to a schematic for this system?

Does it lock reliably when using the switch inside the vehicle?

One fob is brand new from the dealer. Both FOBs have new batteries. The problem is in the car...I can hear faint clicking sound. Also, the dealer confirmed the problem is in the car.

What I need is the car wiring diagram of this system. Please confine replies to wiring diagram.
