I've always been annoyed that my rear wiper doesn't have an intermittent setting. My thought is why couldn't I cut the wire that gives power to the rear wiper and make a jumper that brings power to the switch from the wire that gives power to the front wiper motor. In essence making the rear wiper switch just an on/off/washer switch and when it's in the on position the rear wiper would be in whatever cycle the front wiper is in.

 

Any input?

one problem I see is that if you want to run your front/rear wipers seperately - I do that alot - also you may overload the front wiper control - it is not that beefy (I just had to pull apart and clean the contacts in mine a cpuple months ago)

 

that said, the only way to know for sure is to TRY IT! (just have a spare front wiper control handy )

 

add-on intermitent wiper modules are easy to make/buy - and most are variable speed too - so your interval is adjustable
