Default Rear sunroof not opening

It used to work. But when I tried it recently, I get nothing at all when using the rear seat switch, and when I use the driver's switch for the rear sun roof, it DO get a pronounced click from the "Sunroof EUC" (light gray box mounted above the headliner just ahead of the front sunroof Motor).

I checked the rear switch for power at all four switch contacts with a test light and the audio "Beep" from the test light is very faint at the rear sunroof switches.

I've checked all the fuses with the key on;.....I can't tell which one is serving the sunroof(s),...so checked them all, all the fuses that have power on one side with the key one,....also have power on the other side showing continuity is OK.

Any ideas?

Sounds like the ecu. Try running power direct to the motor to make sure it's good. If it's good I would look at the ecu.
