Hi guys,
This is probably a question that Scott will be able to answer so lets see how we go.
I am in the middle of totally redoing my A/C.
I have always had this problem where the vacum motor for the center vent only opens half way. I noticed that this motor has two inputs. The one on the end will pull the push rod half way when vacum is applied and the one on the side will leak vacum when vacum is applied unless the pushrod is pushed halfway in. Then it will hold the pushrod at halfway. When these two are combined, the pushrod will retract all the way but this will only happen if you push the push rod more than half way in by hand because the input on the side leaks until the pushrod is more than halfway in the bore.
So, is this normal?
Also, for everyone with a VK. When the headlights are on, if you turn the brightness control down for the dash lights, do they turn off when they are turned down all the way.
Thanks heaps
