heater going on by itself . fan also
hi i have 2004 clk320 convertible . i was driving today80 degrees in NY with top down, fan/blower off at 0. After awhile, heat was coming out of defrost and floor areas. unable to stop it. also, the fan has been going on and off by itself while driving, also when a/c has been on , blower fan again goes on and off when it wants....do i have two different problems here? why is the heat coming on?
