Here's the latest.

Spent about an hour disassembling the side of the AC only to find out that the control panel is only accessible from underneath! Put THAT all back together Put some jack stands on the coach and and managed to get the tight fitting control panel cover off. At least i can easily sit up inside the area the AC unit is in. 

Here's what I found out. Unlike the rear dual compressor unit, this one appears untouched. No external relays at all.
I'm attaching some photos of the board ans access panel schematic sticker if anyone has a single unit and needs them.

With the power off to the AC unit checked at the source and at the board (BTW the labels on the House AC panel are wrong...) I wiggled the wires around a bit. Repowering the system now gets me 12V relay sounds for all RED to GL, RED to GH and RED to Y1. Though no fans nor compressors. Next i will test if 120V is running into the board. I do have it at the wires leading in to the board but haven't checked at the connectors.

Being methodical is always best. One step at a time.

More as I learn about it.
