Circuit Breaker in 96 Blazer

The 30 amp circuit breaker that controls the door locks, seats & lumbar keeps blowing. It gets very hot. When the breaker is removed and cooled, you get 1 use out of it before it blows again, so you’d better make it good. My husband has disconnected the lumbar, but it’s still happening. HELP!

Next, disconnect the seats…The connectors are under the seats…

You also might try removing the power door lock relay. It is quite common for a power door lock motor to stick. This causes a huge electric draw and will trip a 30 amp CB quickly.
