A/C is always on?
No matter what position I have the selector switch in, my air conditioner is always on. It works great, nice and cold. But I don't want to wear out my compressor prematurely. Also, the blower motor only works on high, so i get frozen, or hot, no in-between. I believe the blower motor problem is a relay that needs to be replaced. I just haven't gotten to the dealer in a while. However, i don't know what's keeping the A/C on all the time. I can figure most things out on my own and am pretty handy. But I've been searching for this issue quite a bit and came up with nothing helpfull. Most issues I found are related to A/C not working, etc. Any help would be appreciated. I'm not sure if it's hurting my mileage or not since I just went to larger tires and the nu8mbers are all off, but if it is, It would be nice to put that money back in my pocket too since I drive 600 miles a week.
Oh, I always have the vent switch on the position just to the right from 'Off', going to dash/floor(not defrost). A/C should only be on at the AC, Max AC, Def, and Def/floor settings. Dash/floor, and floor should be vent only.
