In that case try using one of the LEDs from Radio Shack and see if it works. Be sure to check the polarity, LEDs only work in one direction. Check the LED you are removing for marks like a flat spot on one side or a silk screen image on the board indicating an LED diode symbol. Let us know how it turns out.
You can check the LED that is in the switch with a VOM. It should measure like a diode in one direction and an open when you reverse the leads. Test with power off, please. If you have a Fluke with a diode test position, it will show a voltage drop and may beep once with the leads connected one way and will show no voltage when the leads are reversed. Keep in mind you may have a bad series resistor.
