Fuse blows when brakes are applied. Replaced brake switch, checked all bulbs and 3rd light, disconnected all and did not solve the problem. Have tried a 30 amp fuse, but when brake is applied, the fuse gets hot. If brake is applied longer than 20 seconds, the fuse blows.
Do you
have the same problem?

That's probably a bad turn signal switch. The 2 lower brake lights pass though it so it can cancel brake lights for turn signals
