Sounds like a blown fuse?
To fix a blown fuse in your electrical system, first turn off the power to the affected area. Locate the fuse box and identify the blown fuse by checking for a darkened or broken filament. Replace the blown fuse with a new one of the same amperage rating. Turn the power back on and test to ensure the issue is resolved. If the fuse continues to blow, it may indicate a larger electrical problem that requires professional assistance.
You can easily replace it but you need to know why it blew in the first place. All fuses are marked on the fuse box or in the drivers manual as to which circuit they protect. Determine which circuit that blown fuse protects and inspect that circuit for troubles.
