Hi all, I am having trouble getting the temperature control wire (blue) to travel all the way up to the 'cold' position. I am using the Old Air cables. I have never seen this control in working condition, so I only have the service manual to go by. Should the temperature lever travel over the complete range of the controller slot, or can it function properly even though it looks like it isn't all the way on 'cold' according to the labeling on the controller? I have tried tightening and loosening the barrel nut many times. Please see my pictures. Maybe I have installed something wrong? Thanks. I can take more pictures if it would be helpful.
