Sunroof Wiring - 740i
'94 BMW 940I Sunroof. A few weeks ago the BMW "small town shop" replaced the front window. Since the replacement the sunroof panel will not operate.
From the electrical diagrams in the Bentley book there are two schematics showing the red & white power to the "switch" but I can't find anything that tells me about all the other wires that disappear in the roof and others coming out of the roof to the switch.
FEED WIRES – go somewhere to connect to switch and motor
Hot Red
Hot Red & Brown
Ground Brown
Ground Blue
WIRES IN THE SWITCH BOX TO OPEN AND CLOSE SUNROOF: (terminal/connection location unknown)
Yellow & Green
Yellow & White
Brown
Yellow & Grey
Grey & Black
Brown
WIRES CONNECTED TO MOTOR:
Insert near large gear drive wheel:
Brown & Yellow
Black & Yellow
Brown
Back of motor (these are larger wires)
Blue changing to Purple
Black & Red Changing to Blue
Where is the location of the connection blending the feed wires, switch wires and motor operating wires?
How do we get to the connection?
Is there a fuse somewhere other than #18 and #32?
