This is what confuses me about the discussion of AC relating to fuel
economy. I have a 93 Honda Accord & I can feel when the compressor
clutch engages & disengages. When it engages I can feel the engine is
under more load(more vibration at stop or slight drop in acceleration or
speed in motion). Surely fuel economy increases when the compressor is
disengaged even with the AC "on".
Thanks for your input.
