LInk to wiper relay post

[chris989]

Hello all,

SInce buying the wife a 2025 burb i felt my 89 deserves a little love.

Next is wipers.
I remember reading a post about adding relays for the wiper motor. (can not locate it now) I did the window relays already and it did improve but not dramatically. I bypassed the switch with relays but did not pull 12v from the battery. I used the original source. When testing i saw no noticeable difference.


Fast forward, Wiper motor, Do relays make a difference?

Thanks in advance.
