If you think it is wired wrong and not the incorrect switch, here is previously shared documentation on many of the common possibilities:
yes, we have already written about this, but these are other switches or other motors or wrong colors, so I can only wire according to the connection / Terminals.
Thus the supposition that the switch and motor are not matched, which is a known issue as described in the aforementioned documentation.
You have been chasing this for a while according to your post history, and there are only so many wiring permutations which you've apparently tried and rejected, so why not try a different solution with hopes of a different (and possibly correct) outcome?
Hey ingo, I apologize for late response and I don't mean to disrupt bmoran, but I own a wiper motor just like what is installed in your truck. It is an extra part I got used a long time ago. I have wired it to test before, using a factory 1956 wiper switch and it worked normal. I do not think it should be the issue.

Hey mORO,
thanks for your response.
You wired it like i did?
The wire from "P" on the Switch goes to "P" on the Motor, The wire from "A" on the Switch goes to "H" on the Motor, The wire from "F" on the Switch goes to "L" on the Motor, "B" is Power to the Switch.
@mOROTBREATH, you are not disrupting. If you infact have the same exact make/model of motor (not one that looks the part as there are many many many), it would be beneficial to know how you had it wired up and if it matches any in the documentation previously provided.
thanks for your response.

or did you anything else?

Tomorrow morning I'll get the motor, a switch, and wire it up really quick. I'll take a picture.

This is exactly as i wired my test setup as well.
Everything works as expected, as should your setup. My pictures didn't come out very well, but you can be sure that I wired it exactly as it should be. My setup worked fine.
Don´t ask me why...today i tried it just disconnecting the "P" plug.
It seems to have something to do with the P Terminal because as soon as I disconnect the plug from the "P", the motor runs as it should in both speed levels, just does not go into the park position after switching off.
Any idea?
Well, P is for Park. I don't immediately recall how the park circuit works on this setup. I'll have to check my resources and see if anything comes of it.

sure "P" is for Park, but why does the connection affect the speed? Somehow i have the feeling that connections may have to be bridged or have to be connected to more then just one Terminal?
Best I can gather is that P supplies power to the motor to park the blades. I haven't definitely determined if this is a constant power all the time, or only powered when the wipers are "off" as the documents in my library are scant on the internals. I do not have a stock switch handy to reverse engineer.
My current theory is that the power being applied to the P terminal on the motor allows full power to the park switch internal to the motor assembly. That internal switch then supplies that full power to the motor itself to move until it is in the parked position. When the motor is moving, say at low speed, and rotates to the unparked position, the full power of the P terminal kicks in (as to return it to the parked position) giving the cyclical power/noise differential you shared. As such, it seems that the P terminal on the motor should only be powered when H & L are not which would be a function of the appropriate wiper switch.
