Newbie to this site and DIY: The heater went out on my car 6 months ago, but I never bothered to look into it over the hot summer in Texas. The weather has been esp cold these last few weeks and I need to get to fixing the heater. The A/C works great but it only blows cold (around 65 degrees). I'm able to change where the air blows (defrost, foot, etc...) and intensity of the blow fan. After reading many others with similar issue, I check the A/C diagnotics for codes and it came back with 31, 36, 41, and 46. I looked around and found the codes for 31 & 41 but could not locate the definition for codes 36 and 46. Does anyone know what these codes mean? I'm pretty certain both the mode servo that allows hot air into the cabin on both driver and passenger side needs replacing. Does anyone know the part number as there are 4 servos for the 2002 GS300?
