Dash fans keep tripping breaker

When operating both of my dash fans, after about 5 minutes, the breaker trips and then will restart after about a minute or two. I removed both fans and they still looked new inside. Good brushes too. One fan runs a little warmer (89 vs 84),but I can't imagine this would be the problem. I ran both separately and the breaker didn't trip. The motor part # on the drivers side is 4000504. Any Ideas for a solution are appreciated. TIA

    Problem fixed after changing out the breaker. Thanks for all the ideas.

    I would check the amps on each fan separately. It could also be that your circuit breaker is starting to fail.

    Sounds like you figure it out. Too many amps draw for the installed breaker. What is the amp draw per fan. Did this just start or this way since new.
