Checking Brakes and Steering on My 83 M35A2

That looks like it’s it. Wish mine still had the On/Off : high /low plate still on it. I will check toggle while Truck Master is off to see if it’s got three positions. I have never touched it as of yet. But I will tomorrow.
Thank You

By the photo of mine. It looks like the heater is in low. The defroster and heater knobs are pulled out a bit. I will take larger photo of dash and how mine is set. I ran Her engine for 40’minutes yesterday morning and didn’t notice heater or defroster on. Never thought it was on any time I ran engine.
Thanks

Yes the toggle is the 3 way. I put it in the center (off) position.
The Defroster and the Damper knobs are pulled out a bit. That’s the way they were when I got Her. Is that a problem ? Now the power toggle is off.
I never heard or felt the heater being on at all while I have ran the engine and the one short trip I took.
Also the Air Filter tube is not there.
I will check to see if filter is good.
Thank You
