I currently have a celing fan that is controlled from two separate switches on the wall: one for the fan, the other for the lighting. I'd like to be able to use a single remote control to control both. I've found remote control conversion kits, but it's made for a SINGLE switch setup. Is there a product out there? Any other way to do this?

You could wire the fan and the light to the same switch, and abandon the second switch.

Perito is right. If you use a remote you will not be able to use both switches.
