Thread: Need help from the wiring guys

Tweet

Just looking at your schematic my guess is that the red & brown are the primary power/ground connections. I'm thinking that the switches on the overhead operate based on those two, and that the red/brown and white/brown are alternate power and ground from the heat & AC, and maybe just the AC. My guess is that if you have the sunroof open and turn on the AC the sunroof gets a close command from the Comfort System. Not much way to be sure from what they show you, as both the motor and the Comfort System are black boxes with no internal wiring shown. I'll look through the manual Charlie linked in later today and see if it shows anything more for the sunroof controls.

Check out the circuit to see what is going on.....do you have the switch module?
Put your 12VDC across the red and brown wires on the 4 wire power connector. When you have it powered, you will probably have 12VDC on pin 2 of the 5 wire connector. This powers the switch contacts. I would guess that the variable resistor is limiting the motor torque so when it closes, the motor doesnt overpower the linkage. Keeping it powered up, try a switch; if it doesnt work, try the other switch. If you dont have the switch panel, jumper pins 5 and 2....does it move? If not, jumper pins 4 and 2. If you dont have the switch panel, DONT close the roof all the way because the motor may have full torque......just tap the jumper wires together to see if it tries to move.

I do have the switch panel and it is one dial that spins to open or close. When I am putting the 12 VDC across red and brown that is on the motor itself and with a voltmeter, right? What are you refering to as the variable resistor? How do I keep it "powered up" with the voltmeter with the control panel plugged in? Stay with me...I'll catch on to it eventually
