A/C hissing fix
I have had this problem for a while on my '01 Z. When I turn the a/c on or off or go from vents to or from defrost, I hear a hiss until the door fully changes position. It has gotten stuck a few times, but mostly clears up on its own. I recently ordered and received the blend door actuator for the drivers side, which is the side that the hissing is coming from. Does the electric actuator have anything to do with the vacuum operated servo? Did I order the wrong part?
When I previously had the dash off, i was able to reach back there and move the servo by hand and it would leak until I moved it fully one way or the other. Will the part i ordered (door actuator with just a female electric receptacle and no vacuum connections whatsoever) work or do I need something else? And can anyone tell me what is actually happening? Thanks in advance
