ralphnewman Posted May 3, 2005 Share Posted May 3, 2005 I just changed a leaking heater valve and had a bit of trouble getting the cable working. It had lots of corrosion and was sticking. It now travels about 1/2" and seems to be working fine. However, The heat coming into the cabin is always the same temperature unless I put it on MAX COLD. Seems the servomotor air mixing Gate (door) is not operating. ANY SUGGESTIONS? Is there something I could have damaged when changing the heater valve? Any help would be greatly appreciated. Thanks, Ralph Quote Link to comment Share on other sites More sharing options...
wwest Posted May 3, 2005 Share Posted May 3, 2005 Remove the cable temporarily from the valve and move the valve into the fully closed position and then test the system. But remember it will take a while for the heater core to cool after you fully close the valve. While the cable is disconnected check its full travel distance from max heat to max cool. Make sure the fully closed or fully open position of the valve isn't restricting the cable travel. Adjust the cable sleeve clamp to attain unrestricted cable travel.
