Solar power is the conversion of solar energy into electricity or thermal energy, either by indirectly using concentrated solar power or directly using photovoltaics – the use of solar panels which consist of various cells made of photovoltaic material.
My 1992 Deville had the heater core go. If your always low on coolant, than this may be your prolem. It's behind the glove box. You unsrew the glove box, slide it out, unplug the lights from it. There is a black cover at the bottom you unscrew as well. You will see a black box with the fan adjustor …

The sun gives out energy because there is hydrogen fusion going on inside it. The great heat and pressure of the sun permits the conversion of hydrogen to helium. Solar power can mean two things. Electricity is produced by collecting sunlight on solar cells which convert light into electricity. T…
