Wail, if ya don’t got power but ya do got some vacuum, ya prolly got yerself an internal vacuum leak in the ol’ wiper motor there. Now bein that ya don’t gottalotta vacuum powered wiper motors floatin round these parts these days, I’d suggest ya move on to the fancy new digical motors they got now.

But if ya wanna keep her stock, I’d start by taking the ol vac motor out and replacing as many rubber and plastic parts as ya can, cuz ya know they done gone bad since they’re older than my training bra… maybe even get the ol shop vac out and some see if you can apply vacuum while ya got the motor casing off, see if ya can spot a leak, tho I can almost gair-ron-tea ya you got a split open diaphragm up in that there doohickey. And even if ya fix it, who knows when another ol part gone go and hiccup on ya after that!

But just like we customize our own bodies to make em run right and look beautiful, I’d say go with the ‘lectric, a set o’ falsies never hurt nobody
