In trying to take advantage of this warm March break, I thought retracting my sunroof would be a nice idea. It turned out to be only an idea: the sunroof switch did absolutely nothing.
The manual says the fuse/automatic circuit breaker is in passenger compartment (Box C) located on the left side of the dash. There is a number 25 & 26 with asterisks, but no fuse slots. The asterisks denote automatic circuit breakers. The 25 is for power seats* and 26 is for power windows, POWER ROOF*.
Before I check the switch, does anyone know what an automatic circuit breaker looks like? They appears to be three relays next to the fuses, one with a J on top of it.
I know it is probably in front of me, but I am just not getting it.
Thanks for any expertise!!!!

Fuse: 11A-3 (panel 11A, engine compartment behind battery; fuse #3)
Circuit Breaker: 11C-CB2 (panel 11C at left end of dash; top thingy of two to the right of the 3 relays)
Relay: 11C-2/6 (panel 11C, relay #2/6; top relay of three arranged vertically along right side)
I'd start by pulling relay 2/6 and look at the bottom or side of the relay to identify which terminal is #1. Make sure the corresponding terminal in the relay socket shows 12V+ (ignition on), this power comes from CB2.
If that looks good, pop out the switch and check for power at the terminal with the yellow-red wire (ignition on). If that looks good, then the switch is suspect. If no power, then the relay is suspect.
If the switch is suspect, unplug it and jumper the plug terminals with the yellow-red and red wires, the roof should start to open; jumper yellow-red to blue to close.

It had appeared that the culprit was the circuit breaker. As soon as I had replaced the sunroof, it worked again. The next day, when I was extolling the virtues of Volvospeed and displaying the handiwork, the sunroof was dead again, even after replacing another circuit breaker.It looks like a short somewhere, but I will follow the rest of your advice.
Still extolling the virtues of Volvospeed.com though. THANX!!!!!!!!!!!!!!!!
