1992 Trans Sport Power Mirror Problem

[MTNRDR]

Both my mirrors suddenly stopped working. I suspect a fuse or a relay but can find neither. Does anyone know where it is located or have suggestions on the cause of the problem. Thanks much

THe fuse is CTSY FUSE 15 amps, in glove box fuse panel
www.avigex.ca/xport/fusepanel31.jpg or www.avigex.ca/xport/fusepanel38.jpg ..depending on engine type, same place anyway,...but were it blown, door locks and courtesy lamps , floor and glove box, would also be disabled.
.. for both mirrors to be out, and nothing else, either the 12v or ground to the switch must be failed, or the switch itself is shot.

I tapped into the ground to the mirrors and regrounded it and now they are working just fine.

I pulled the door apart last week and checked for 12v and ground on the connector to the mirror switch. Thankfully 12v was there, but ground wire was no longer grounded. I ran a wire from the dead ground wire to the ground wire in the power windows bundle and the mirrors are working fine. Thanks very much for the advise.

You are absolutely bang on. As I mentioned above I did trace it to a bad ground. Kind of bizarre that the ground would go bad but I'm not about to try and trace that one down. I re-grounded in the power windlows bundle and it's great. Thanks very much for your help.

From what I am seeing with these vans , they are like the Fiero's in the grouning of wires. When I had the Fiero I had to reground everything. I even ran a bigger 2nd ground for the motor.
