Hi, my name is***** will be assisting you.
The most likely problem that you have is a bad damper control. There is one on either side of the machine and normally when one side goes bad the other one isn't too far behind. It is Toro part number #103-2913 and can be purchased through your local Toro dealer or online through a number of different websites. They both are the same so there is no difference left to right if you wanted to get two of them and replace them both.
Thank you it has been a pleasure to assist you.

I have included a diagram for you so that you can see what the damper looks likes and where it is located. It is reference #8 in the picture.
