I have a 2004 chevy Malibu maxx the brake level sensor went bad I replaced it it fixed problem and cruise control worked again to drove it 5miles and did it again now what

Perhaps the sensor wasn't the fault? Disturbing the wiring connector and harness could have caused continuity, and now maybe it's gone? Hands on testing in the circuit is needed to find out what is going on. Use this link to find some shops near you that can help with your concern: www.repairpal.com/repair-shops
