The engine of the stove of the car stopped working, having disassembled the engine of the stove, he saw the concessors, why are they there?

Question

Electronics

Good time gentlemen!
The motor of the stove stopped working at the car, I decided to fix it on my own. In the field of electronics, I am not selenium, but there are still some basics, now I need your help.

Having disassembled, I saw that 2 capacitors were connected here (I hope I was not mistaken in recognizing) if you look carefully here you will see one, marked 680. And it is connected to both "+" and "-" and this led me to a dead end, I I do not understand why ? why is it connected in parallel? This is question number 1
The second question, as I have already indicated, there were 2 connected, the second one had one paw on the "-" and the other dangled. Logic suggests that the same thing was connected in parallel, by the way, it has the marking 104.
I tried to ring the conders with a tester, 104 does not ring, I think he’s a khan.
Oh yes, question number 2, is the logic telling me correctly about connecting the conder 104?
And question number 3, if suddenly I don’t find 104 in the city, what can I replace it with?

Answer 1

1. Serviceable capacitors are not called by the tester. So it should be, it is 99% correct
2. With faulty capacitors, or without them at all, the motor should still spin. They stand to dampen interference - so that the radio does not crackle.
3. It's easier to buy another serviceable motor, even a new one, even a used one, and replace it.
