Have anyone replaced the rear one yet? Mine buzzes and I have No Heat in the rear at all, even on max temp. A/C works fine. I bought two of these sensors, one for front and rear. My front finally stopped buzzing and died totally and have no heat until i put HVAC control on max (in front).
How much of the roof liner needs to come down, or is there an easier way?
