[Carl n Susan]

Is there any sound (from the pump) when trying to bring the slides in?

How about trying to extend them (I know they are out, but does the pump kick in)?

If the answer to these questions is "yes" then likely the problem is with the slides themselves (likely a sheared bolt).

I suspect the answer is no (to at least one question). In this case check the pump in the front compartment. Besides the power wire, there are two other wires which connect to the pump (look for the spade connectors). One controls the "extend" motion, the other controls the "retract" motion. I bet one of them has come loose (don't ask me how I know). The other option is no power at all which indicates the fuse has given up. But since it is a self-resetting type, I think it is unlikely.
