My Tekonsha Prodigy is maybe 10-12 years old. Recently when towing, the numbers on the controller did not go from 60 or so down to "c". Normally when I let off the brake, it goes to c almost immediately. Was afraid my brakes
were staying locked so I pulled over and played with the connection at back of truck. Finally they went to c. Brakes
did not seem to be hot. Started doing it over and over after I applied the brake . After verifying the brakes
were not hot, I tried to ignore it. Finally, realized that if I ignored it for about 20-30 seconds, it went to c all by itself. Do I need a new controller? Oh yes, the brakes on the trailer seemed to work normally.
