My turn signals will intermittently quit working and odd clicking sounds will come from the switch. I recently purchased this car and horn also does not work

turn signals (emergency)flashed when alarm sounded
after disconnecting Alarm, no more turn signals, horn will not sound

An accumulation of dust inside the body of the turn signal switch can cause a partially closed circuit, which results in the turn signal relay intermittently clicking at a high rate. Spraying a small amount of residue-free electronic contact cleaner (such as Electrosolve) inside the turn signal switch can resolve this problem. The turn signal relay is not the root cause of this problem, but may be damaged by it.
