The other day I worked on an SVX with no sunroof.
The power seat worked but the windows would only click.
Removed the drivers seat, pulled up the carpet (PITA) and replaced the old burned four wire connection going into the window relay under the seat.
I used four seperate female blabe connectors and encased them in shrink tubing insulation so that they would not bump/arc each other.
Plugged it all together, tried the window, and watched the "magic smoke" puff out of the relay.
Not wanting to wait for an actual Subaru part, (this was on the weekend) I ordered and failed to recieve a Mitsuba(RC 2201)brand relay, followed that up with a Beck/Arnly that did not work
, and finally another brand that did work.(Its 5:30am, and I'm not wakin Di for that info.)
The relays ran $41.08 as I recall.
Hope that helps.
The relay that I used was IMC brand, part #83521007060
