Preface:
It is a 07 H3 79k'ish

It has been -11deg. Or colder last couple night...
Wipers last worked Wednesday 012319

Problem:
Went out this morning and the wipers have zero movement... Zilch, zero, zip!!!
The multi switch can be set to any speed and nothing... Windshield wiper fluid pump is fine.
Diagnosed fuse #6???
Diagnosed two relays and one or two diode's???

What are the correct relay part #'s (SMP ry604, ACDELCO 21997408, acdelco d1780c, airtex 1r1059)
What are the correct diode part #'s (gm 12135037)
Fuse #6 value was 25 amp mini ... Is this correct??

Solution:

Is it possible that the Motor just cr@pped out?? (GM / acdelco 10389558)
Maybe the diode's???
Maybe the relays???

Please help!!! Lol!!
It is supposed to be very, very cold this week (-20+)

Wiper motor relay PN: 1R1059 or 1581106.
These can be bought on RockAuto for next to nothing.
Check out schwarttzy.com he has the manual that will help you diagnose your wiper motor to see if it’s bad or not.

Well wobbled the stalk around and left H3 till afternoon and checked everything twice. It works at the moment again but who knows why it stopped.

My motor worked off and on a couple of times before it died.
