Rear wiper arm fell off....

[Charlie207]

Lots of snow yesterday, and on my way home from the mountain I tried to remove a bit of the snow buildup. Clicking the switch to run the rear wiper and I heard a faint crack. I just figured that.... who knows. When I stopped at a gas station to wipe off the snow I saw the entire arm dangling by the fluid hose.

Is there a better version of a new arm to buy over whatever is available on Scamazon or Rock Auto?

Before anything else, I would want to know why it came/fell off.

Is the motor transmission still good? Splines still good? The old arm was plastic? I personally clear snow away before turning on wipers and the heat grid at rear should keep it melted enough to wipe ok. At RA, a Dorman rear arm is listed and is metal. When I replaced mine, right after I got the rig, I found a NOS at a local dealer and snapped it on with a new wiper blade. Here in the valley floor, we don't get much snow though.

Snow was cleared, and rear-defroster is always used, but the timer on that is something dumb and short, like 2 minutes. On top of that there was a no-kidding blizzard of heavy/wet snow, that clings to the rear window.... I'll take a look at that Dorman unit.

There should be a little locking tab that you must slide over for it to stay locked onto the spline shaft that comes out of the wiper motor. Maybe that is loose or damaged in some way and isn't holding the wiper arm on.

Not the case.

Lots of broken plastics and separation of a major section of the arm from the vehicle. No coming back from this one.

In a little bit. Stuck in a meeting.

You can see the arm has the end of it broken off.
