Power window (1994), rear right, no go, what can I expect to pay for repair?
 

My rear passenger power window on my 94 Accord stopped dead 4" from closed.
There is absolutely no noise (clicks, moans or groans) from it from either
local or
driver side activation.

What can I expect to pay for repair:

If Motor is cause:

If switch is bad

If black box (if it exists) is bad?
