What are you using as your ground when measuring the voltage coming from the switch? If a wire comes to the switch, another leaves the switch and goes to the bulb and the bulb is grounded then you should have 12V at the switch. If you don't have 12V at the switch then you need to check fuses and/or damaged wiring.When you get an odd voltage reading on a device that was once working then you have something that failed and the best fix is to find out what failed and replace it. Not hook up some device you pulled out of your imagination to fix a problem you have not troubleshot. The problem in this case is that for some reason you are not getting 12V to a device that should have 12V to work. The problem is not that you have .95V and you need it to be 12V.
I am using a voltmeter on the two connectors coming to the light bulb. I checked the fuses in the fuse box and they are all fine.
