When my car is running it runs fine and there are no issues, but when i turn it off I get a rapid clicking out of the back up lamp relay and the horn relay. Does anyone have any suggestions on what my be causing this? I did try a new a relay and I get the same issues.

do your horn and buck up lamps correctly? cleaned the battery terminals? have any other charging or battery isses?

Not that I've noticed...but I'll give that a try

alot of times the clicking is caused by lack or ground capacity or power with bad connections

both of those go to the b plug of the bcm too, i guess i would try reseating them a couple times. it says it behind the instrument panel with 3 plugs.
