DevoPROCw

I've dealt with this for over a year now, my wipers started to quit intermittently then days later quit for good. I've replaced the motor, re soldered the multi switch contacts, then replaced it also. Checked my fuses and the motor and switch are both getting power. I've searched everywhere online but nothing seems to come up for the jzs147 :/ it's been to 3 shops who can't get it figured out, wondering if there is a relay somewhere blown maybe? Long time forum reader but first time poster. Hope somebodies got some ideas so I can stop relying on rain x lol
