A break in an electrical circuit will cause the circuit's load to stop operating.
When a circuit is not closed it is not operating.

If it is a properly wired circuit (according to code) in the home, the breaker for that circuit will trip deenergizing the shorted circuit. If it is not properly wired, it could get hot and start a fire and possibly burn down the home.

It will not be possible to measure current unless the circuit is powered and operating.
When a circuit is open, electrons do not flow at all. They do not go backwards or stop within the circuit because there is no complete path for them to move through.
An ammeter is a device used to measure electric current in a circuit. Its main function is to provide a quantitative measurement of current flowing through a circuit in amperes. By monitoring current, an ammeter can help users ensure that the circuit is functioning properly and within safe operating parameters.
the blend door may not be operating properly, or a vacuum leak may be present.
