Help, I have a 2003 Monte Carlo. Here is my problem, when I turn the car off the relay switches start clicking on and off. This makes my headlights blink on and off, as well as my backup lights, and tail lights. When the car first started doing this I cleaned all of the terminals to the relay switches, the fuses, and the battery cables. This cured the problem for a few days, but now it has returned. Does any one out there have any idea what the root problem might be?

 

i am having the same problem with my 03 chev silverado anyone have any idea what it may be?
