There are a couple of red button type circuit breakers in the engine compartment for mine. Try those first.

Sounds like they just lost the power to activate them. There are also some quick connect fittings on them you should check for good connections.

Should be something electrical, you can check the voltage they are getting by disconnecting that quick fitting at the actuator to verify good power.
