Electrical issues

[Sweetman]

I'm have some electrical issues with my 08 lucerne. The drivers parking light dont light up. The drivers side doors locks dont seem to work right. My trunk wont open. The parking assist seems to work here and there. And the horn dont blow loud. Has any one had any of these issues all at once.

I replaced the bulb in the parking light and old one was good. Turn signal works as it should.

Can you provide more details as did they all happen at the same time or did they start one by one and never got addressed, milage and if it's a vehicle that where road salt my come in to play, any CEL?

It seems it is wiring harness on some, critters may have chewed on them (?), loose or bad connectors, could be the fuse box rear seat shorting out, trunk release may be bad but not sure it's the remote - interior button or both, door actuator or master control on the lock.

Everything had issues when I got the car. I been driving it for a few months now. With trunk not working you can push the button on the remote and dash and hear the solenoid click but nothing happens. I tracing down the wiring harness for that in the truck. I herd wires could get pinched. With door locks the remotes and door lock buttons all work but it seems the drivers side doors locks dont seem to work right. The sometimes lock sometimes not. The horn blows very weak. Sometimes you can hear it sometimes you can't. The parking light on the drivers side dont light up. I have changed the bulb but still nothing.

Unfortunately taking on someone else's problems means troubleshooting from the point of origin and work back towards a good point no quick fix. It will take a meter and time to check out the harnesses and the connectors. The door could be a actuator, master control or again a harness short kind of open until something is confirmed good.
