Front windshield wiper switch

I have not had my 4-runner for about 3 weeks due to a inop wiper switch in my 1989 4-runner. It needs it to pass the PA, inspection. Does anyone have an extra one or better yet where I can get one. The place where I have it at now tried everywhere and has no luck finding one and the right type. I just want my 4 runner back, so I am trying to help them look for the final piece of the puzzle for the inspection. So if any one can help it would be great.

Thanks,
MG
