Ok, I have my bracket made for my window motor on the blower. I'm ready to start wiring to my momentary switch and the photo attached is the way I believe it should be wired up? Any problems you guys see would be very much appreciated!

Only thing I can think is does it need a relay?
What is the amp draw of the motor?
What is the amp rating of the switch?

If I'm understanding your schematic correctly, it looks like a dead short. All three terminals on the switch are +; in this case power-in, forward and reverse. You would not ground any of these terminals. Only grounds are at the motor (either through the case or a separate terminal from the two shown) and at the battery negative.
Or maybe I'm just misunderstanding the two marks coming off the left and right of the switch.

I'm going nuts here! I tried two different ways of hooking the three post momentary switch up. The first way in the dia. which did not work. For reasons specified I believe in the last reply. Then I tried it as described by delikocc. Still no go! Before I attempted the before said mentioned set up I tried this switch which was a 7 pole switch.

I'm just not sure what the heck is going on here. I usually can figure out this stuff but this one has got me puzzled!
I'm so frazzed if you know what else I can do PLEASE let me know.
Regards,

I should have included a picture of the rear of the 7 pole card:

You need a dual pole double throw switch DPDT for reversing polarity on a DC motor .

J,
I figured the switches were not right. I'm just glad you hade the key to unlock the mystery box here thank you very much. I will give McMaster a call and order the little bugger up ASAP.

Brian , I should have mentioned that ideally you would want a spring loaded momentary DPDT 6 terminal toggle switch with a center off position . I would think any reputable hardware store like ACE hardware would carry it. I looked at the ones at McMaster website but the description of their toggle switches confused me , so I'm not sure .

J,
I got it and it is spring loaded. I installed it and I'm happy to report that the motor now functions. I believe I'm almost ready for the snow!
