1980 450SL. The ACC servo is leaking coolant. The plastic case is cracked. Has anyone successfully taken it off and epoxy it? Alternatively can the ACC servo be bypassed. Do you loose both heat and AC when bypassed. looking for a temporary (hopefully somewhat permanent) simple and cheap solution. I'm loosing coolant. The cost of a rebuilt servo is over $350!
