$6,500 formy 96 c-280 sport, has lorinser exhaust and spoiler, 148k with new fan motors.It was blowing warm AC and the fix was part of the deal. I'm in the middle of first plug and connector change(thanks Athor Dalton and others), and found the vaccum line unplugged under manifold. The last oil changer left it hanging in the wind. My rear headrests now retract . This site is the best! but the lady gets alittle jealous of the time I spend on research . Thanks all
