2001 Spyder convertible top won't open

A friends Spyder convertible has a open/close switch on dash.
When toggling switch to "open" position nothing happens, no sound,
nothing.
What should I check first...fuse? Which fuse is it?

Is there a switch in the trunk to check?

TIA

get your owners manual out and look under fuses...i know there is one for the top. If there is nothing happening it probably is a fuse....and if not that then a blown motor.
