It sounds like the control board has failed in regards to the lighting section or does it have a separate switch? The parts list has something listed as 'interface' . It is a $197 guess though for the control board! Did you remove the 4 halogen bulbs and test them with a multimeter? You should be able to test the switch.
The fan switch contacts are probably welded together or the actuator mechanism is broken. Your best bet is to replace the fan switch, probably with a similar type having a higher current rating so the new one won't also be susceptible to contact welding. If you have an industrial electrical supply dealer or electronic surplus parts store in your area, those would be good places to look for a replacement.
It sounds like your switch is getting stuck internally. It most likely needs to be replaced.

If it is a Broan, there is a delay button that was also depressed. It will turn the fans off after a few minutes. If not, then you're shorted out either in the control panel or the wiring in the range hood.
