Question:
Husqvarna ST327P snow blower. Auger does not lock when both traction drive and auger. This feature is explained in the owner's manual and it's to allow the operator to remove his right hand to manipulate the chute control without having the auger stop. It would also be helpful to allow changing drive speeds without having to stop.
I purchased the snow blower new last fall but didn't use it last year due to lack of snow. I used it for the first time today.
Inspecting the mechanism, I see a plastic interlock cam (part # 532 44 52-91) with a ledge that apparently the mating auger control should lock onto when the traction drive is engaged but the ledge can't lock onto the metal part of the auger mechanism. In fact, I can't see how it could work because the ledge isn't deep enough to enage the auger part which just slips by it. (It's difficult to explain.)
On closer inspection, I'm not sure that the plastic ledge of the interlock cam is supposed to engage the metal piece. When I engage and then disengage the traction drive while the auger control is engaged, I hear a slight click coming from the area of the interlock cam but the click is not coming from ledge on the plastic piece as it passes the metal part but I can't determine where that click is coming from. I work on virtually everything but temperatures are now about zero, my shop isn't heated, and more snow is coming. I don't want to take the control shaft, springs, and all the other parts to fix this now. It's too cold.
The machine is under warranty but I have no way to take it to a repair center. Do servicing dealers have a pickup service?
I see that someone else posted this question a long time ago but received no response. I would appreciate help with this because it was clear today when I used the machine that that feature would be very useful.

Details:
Please see attached picture. The problem can be seen near the center of the picture. The ledge on the black plastic piece will not engage with the edge of the mating metal part. It just slips by it. This picture was taken with both the traction control and auger controls fully engaged.
