i have another 210 AC question -- my 97 420 the blower stays on high all the time when the system is on any temp or speed its full blast or nothing and cant be slowed down with the speed control that shows the speed up and down on the A/C dash unit -

is their a control that defaults to high speed only / the air is cold and the heat is hot its just the spped of the blower cant be controled by the dash controls --


the system has worked fine for 4 years than one day its brain fell out THANKS - jz
