I have a 2007 Outlook and the wipers are only working slow and I mean slow! On all speeds.

Either the wiper linkage is binding or the wiper motor is failing. Disconnect the linkage from the motor and check the movement of it. If the linkage moves freely, replace the motor.

Thanks I'll give it a try

Mine was doing the same and even ended up stopping while in use! The following morning I ended up spraying some LPS1 (sort of like WD40) underneath the cowl cover trying to hit all of the linkage. To my suprise it seemed to have fixed the problem. That's been a few weeks now. I plan on getting in there and spray some good lube in there.

My wipers have started moving slowly in all speed settings (but does not stop as some have reported). Perusing the net this problem could be caused by: 1.The Wiper Motor, 2 The wiper transmission, or 3 Electrical (gosh I hope not).

Searching around on the net the most common fix is to replace the motor followed closely by replacing the wiper transmission. How can I tell which is the culprit? There is a great vid on how to get all that stuff so I can handle replacing the defective parts as a DIY.

I'm leaning towards obtaining the motor in advance and replacing it so I don't have to take everything apart twice and avoid paying full dealer markup on the part. Downside is, if its not the motor I'm out the $$$ for that part and still need to buy a part on the spot while I have everything disassembled.

I have noticed the same thing on the rear wiper of my Chevy Equinox. If I don't use it for some time it will operated SLOWLY. I hit it with some WD40 and it works just fine. I'd try this before tearing into the wiper motor.

Tried the WD40 approach and aside from making the cabin smell like WD40 no noticeable difference. I have noticed they almost jerk across the windshield ever so slightly. That makes me think its the windshield wiper transmission.

Wrapped up this fix today - it was the wiper transmission as I had guessed. Extremely corroded to the point that one of the arms / spindles would not move anymore.

There is a great video tutorial on how to get at the wiper transmission and motor online which I used.

The most difficult task was removing the wiper arms...pulling them required a ridiculous amount of force, even when using a wiper puller. The first puller I used was too small to get the driving screw properly centred on the spindle:

After a couple hours of messing around with that one, I went out and bought something larger and more suited to the task at hand. This is actually a battery terminal puller but it did the job:

One other pitfall I had was that with a broken wiper transmission I didn't have a reference of what the "park/rest" state was for the arm that bolts onto the motor spindle. The first time I put everything back together the wipers ran backwards. The arm should be attached at 90 degrees to the top of the motor - pointing the same direction as the electrical connection. Apologies that I don't have a photo of this - I forgot in my haste to take one.
