I have good pedal and I have checked the switch at the emergency brake and it is working correctly, the only way I can make it go off is to unplug the wire that goes to the proportioning valve. Is the switch in the proportioning valve replaceable or do you have to replace the valve itself? Thanks in advance

Possibly the switch behind the brake pedal. There is a switch for each tail light as well. Mine has been problematic and I am in the process of troubleshooting mine.
