First have battery checked!
Take the battery to your local WalMart, they will test it free. Have you checked the water level in the battery? There may be a fuse blown somewhere that goes from the battery to pop-up. Look under the frame on the drivers side, just behind the tongue, under the floor for a circuit breaker or fuse.
