Wipers are “cold” sensitive?

It’s been frigid here in Denver for what seems like an eternity. We got a cold snap and a good snow two weeks ago and ever since, my wipers will not turn on until engine is at temp + 15 minutes of driving. The motor makes a funny noise when I turn them on.

Speed/intervals fine and it still shoots fluid like a racehorse. Any suggestions? Is it possible that the motor needs something like a good cleaning? Grease? Trying to avoid replacing

2010 JKUR

Thank you.

Maybe I'm missing something from your description, but is it possible the wipers are frozen to the windshield? When I lived in the frozen tundra, I had to peel them off the windshield and knock the ice off them sometimes.

When did your freedom to make stupid choices become my responsibility to pay for them?

Nope! Just slow to start and when they fire up the motor sounds funny.

if you got weather that cold , I'd wear thermal underwear. However , I think the motor in your wiper system is goin' south on you & am implying it's not maybe not due to just cold any longer, .
Personally , I would extract that wiper motor and arms to 'go over ' it ( ie- clean , lubricate , diagnosis, repair ,replace) if mine were groaning and seizing.

i can confirm...wiper motors are NOT cold sensitive. i am sitting here posted to Siberia at the moment (literally)...with -35 temps (WAY colder with windchill). wiper motors are fine. yup...the fluid freezes (rated to -45 my ass)...and like previously stated the blades themselves will freeze to the windshield, but aside from that...no "issues".

one thing i have noticed is that the relays tend to act funny in the extreme cold. for instance...my brake light relay is VERY loud on the super cold days . Odd i know, but it "clunks" on super cold days...but when it warms up, the "loudness" goes away. (still works though).

J3ff!!! I knew you’d come through. Keeper and wizard of the vast wonders of these forums is there a write up / thread on the dissection of such? I peeked through Haynes but it’s cold and I couldn’t find much past a wiring diagram.

I just want to know how/why you’re in literal Siberia!!

Thanks for the advice though

Uh, let me use my magic , crystal Google ball .....

ok, the oracle of Google has replied with an answer to my question! Hail , mighty seer of all, the Google may it be praised....

It returned this , my wipe-seeking friend.

That would get me started and enough along to do what needed to be done , ymmv

I hope you get to leave the gulag soon. Maybe fashion a Mcguyver style lockpick / weapon from the old wiper blades and the bad motor to aid your escape from Siberia?


Good luck & plz update this with your results !

beginning with the most obvious...

Not to be at all offensive, but could it be that your blades are frozen in place at first, so they cannot operate?

I've never had a failure of the wipers to operate in cold weather - unless they are bound by ice.
