My switch went out in my 92... I blew it out with air a couple times and it worked a couple more times.... it ended up sticking in the up position. I could roll it down but had to press the window lock to make it stay or else it would go right back up on its own. Eventually it failed all together and I had to use the rear key switch. (Yes the key switch is on a separate circuit than the interior)
I couldnt find a rocker switch to work in its place... but after I replaced it from a 92 roll over I bought for 500 bucks (complete with running 3.slow 5 spd and all mechanical... including 4.56's....anyway) I found that NAPA had an assortment of rocker switches that may have worked. Pop it out, unplug it and take it to NAPA... A.zone, Oreilly and Advance didnt have squat for my needs.
Good luck, parts are getting HARD to find for 2nd gen's.
I HAVE MOTORS, PANELS, SWITCHES AND GLASS FOR ALL OTHER APPS THOUGH
