mine is working now replaced the brake switch and wiggled the plug by the master that was put in in the recall and it started working. I am thinking it was the brake switch, I also made sure the switch is in the correct orentation it has to be perpendicular with the pushrod from the master not the break pedal to get the entire movement of the contacts. Also noticed where the weird smell is coming from in my truck the master is leaking into the the drivers compartment, so the smell is Dot 3 oil. The firewall is covered in oil.
