My door locks are acting up, they won't lock with the key fob or with the door buttons. When I press the lock button on the key fob the horn honks but the locks do not move. When I press lock on the door I just hear a click under the dash (passenger side) and nothing else. Only way to lock them is manually. Any insight would be appreciated.

 

Is it both doors? If so, this is a common thing - https://ls1tech.com/forums/general-m...cking-fix.html
