JINX3MT Posted January 21, 2019 Share Posted January 21, 2019 I have looked at all the 1990-1991 sunroof posts and have yet to find any troubleshooting or pinpoint tests for the sunroof electrical circuit. All I see is leak and install issue for the most part. The sunroof worked fine and then just stopped working. I have power coming to my switch and it seems to be coming out as well but If anyone has pinpoint test procedures for the sunroof circuit it would be much appreciated. Thanks in advance.

john in KY Posted January 21, 2019 Share Posted January 21, 2019 I'll take a shot at it. The switch in the overhead I would think is sort of 2 switches in one. In one position it allows current to flow in a direction that causes the motor to turn CW. In the other position the current through the switch flows in a different circuit allowing the motor to turn CCW. Because you believe you have current leaving the switch, you are testing only 1/2 of the switch. Just guessing here but there could be 2 wires on the motor side of the switch. One will be hot when the switch is one position and the other cold. Place the switch in the other position and the cold wire should now be hot. Could always pull the headliner and then test the motor or what I would do is just replace the switch. A member over on the Subaru Outback forum, can't think of his handle, helped me a few years ago when I had sunroof problems. Quote Link to comment Share on other sites More sharing options...
JINX3MT Posted January 21, 2019 Author Share Posted January 21, 2019 Thanks john. I may just pull the headliner. Does power go through the switch to the relay under the dash then the motor, or from relay, to switch, then motor? Quote Link to comment Share on other sites More sharing options...

JINX3MT Posted January 22, 2019 Author Share Posted January 22, 2019 Thanks for the link heartless. I'll look at the schematic. 1 Quote Link to comment Share on other sites More sharing options...
