In a CL, the AC compressor runs continually anyway, the cabin function switch only allows the duo valve to be fed the cold air or not. But the effect on mpg is permanent.ah ha. I tell a lie. It remembers the last setting you left on the air-con-off button - so when you get in the car the next time if you left it with the air-con off it starts off with that setting.
This is an improvement on what I thought it was doing. I'd still prefer the light off when the air-con is off - but at least I don't have to re-set it every time I get in the car.
