hold the key in the start position while pressing the horn, if the horn blow strong the battery is good, if it's weak replace the battery. if the security light is on or flashing when you turn the key on, reply back. the best thing to do with those relays is swap them around with the same ones to see if that help, if not thats not the problem, if all checks out ok, take to a GM dealer you may have a module shorting out the module communication. good luck. and please accept my answer. thanks T-MAN
