I have an '96 SL that I am trying to milk as long as possible. Does the A/C compressor run less when you have the temp slider more to the middle, or does the compressor run the same and the temp is raised by letting in some warmer outside air mix in?
Sometimes I like to set the temp so it is just a little cooler than outside, but if my compressor is running just as hard as full cold, I'll quit doing it to save the compressor.
