Question about 2003 Chevrolet Impala

1 Answer

Fuse for locks constantly blows

The door locks (2oo3 Impala sedan) do not work with the remote or from inside the car. I hear the relay click. Checked the lock motors, took door panel off and checked wiring...replaced blown fuse. It worked 4 times then blew the fuse again.

2008 Chevy Impala LTZ: car wont lock or unlock with the power lock/unlock buttons on the remote or car door. It makes a clicking sound though when I attempt to. Is this a blown fuse? Or something else


Where do you here the clicking sound ? in the door , behind instrument panel ? I don't think a blown fuse would do this , possibly a relay ! do you know what a relay is ? This is Chevy factory service information !
Door Lock Operation
When the body control module (BCM) detects a transition of either of the door lock switches to the lock position, it switches the door lock actuator lock control circuit to voltage. Since the lock actuator unlock control circuits are at ground potential within the BCM, the door lock actuator motors transition to the lock position.
There are three pcb relays integrated into the instrument panel fuse box ( non replaceable ) door unlock pcb relay drivers door -door unlock pcb relay an door lock pcb relay ! The BCM controls these relays ! Do you know what a BCM is ?
Circuit/System Description
The DR/LCK fuse supplies battery positive voltage to the I/P fuse block for the door lock system. The body control module (BCM) supplies and monitors a reference voltage to the door lock switch through the door lock switch lock/unlock signal circuit. The door lock switch also receives a constant ground source. If a door lock switch is placed in the lock position or unlock position, the reference voltage is taken directly to ground and the BCM detects the voltage drop on the signal circuit.
The BCM, upon receipt of a door lock switch lock or unlock signal, will switch the appropriate door lock actuator control circuits to battery positive voltage. The opposing side of the door lock actuators are connected to ground internally within the BCM through the other door lock actuator control circuit and the doors will lock or unlock appropriately.
With out have a factory GM tech 2 scan tool ,It would be best if you took this to a Chevy dealer . The first part of diagnosing this problem is to hook up a scan tool !

2001 volvo v70 tailgate lock/unlock relay location. Tailgate not locking checked fuses, no sound from tailgate, however do get click sound from fuse area.


Check the wiring to the rear hatch. The cables break and cause a variety fo problems like yours. You will have to take the plastic cover off and expose the cables.

Door locks stopped working


do you get the master panel wet(drivers side main switch) I would get a new master switch from a junk yard( about $20). If that isnt it, check your fuses under the dash and relays under the hood(black box)

The auto door lock feature dose not work.


There is 3 relays in one of the fuse panels that are labeled doorlocks one of them is probably bad. Push the door lock button and find the one that is clicking this is the one that is back. This should fix your problem
