Let’s start from the beginning. It is highly likely that something you touched when starting this process is the culprit. It is IMPERATIVE that you answer the questions, all the questions, to get to the root cause if any of us is to help you.

I went back and read carefully the original post. Here is what you said.

I extended the slide room fully and then retracted it about 1/2 way so I could get to the limit switch to make the slide room under-extend. I removed the limit switch and attempted to retract the room. Nothing, nada... I can hear the pump running so I checked the fuses 85,86,87,90 as suggested in the Rosetta Stone of HWH diagrams. The fuses were good (tested with an ohm meter). I checked at the solenoids to make sure I was getting 12-volts to them - the unlock wire is energized when the retract or extend button is pushed (and the locks themselves are open/retracted). The extend and retract wires are not getting anything...
So I decided to jump the unlock wire to the retract solenoid just to check it but still nothing - a test light confirmed that there was 12-volts through the wire to the solenoid...

So, if you can please fill in the missing info.

When you removed the slide limit switch, did you disconnect the wiring, or just remove it from it’s bracket?

Did you remove BOTH limit switches?

How did you get the slide from the partially extended state that you mention above to the fully in state?

We can go further when we know these answers.
