1988 190e seat switch
 

Good morning. Im too poor to buy this switch today so I thought I might try to fix it. I thought I remember an article not too long ago that showed a fellow " restoring " the electric seat switch that we find in the 201, 126 chassis cars. Does anyone remember where it is ? My switch will not operate in the forward back mode. It feels like someone spilled a coke in it. I know that would be hard to do but thats what it feels like. All the other functions work. Any suggestions ?
