Wiper motor seal
 

I had this wiper motor out to bench test a new washer pump. Looks like the cowl seal may have been nothing more than RTV. Any advice on re-sealing?

Edit: I just did a google search and found several different styles of seals. So my new question is which style have you had success with?

And I also see where that's a seal on the shaft. Shoulda looked closer before I posted this!

oh wow I thought they were sealed with seam sealer. Guess now I know what I need to buy.

I'll be reinstalling my wiper motor soon also... The GMC Pauls website shows 2 different seals. I'm under the assumption that a truck would use both. One that seals around the shaft on the motor and one that would sandwich between the cowl and the wiper motor. Does this sound correct? I'm wondering if one of the seals is an updated version over the original and only one is required.

I installed those same two seals from gmcpauls, and they fit great. Was a big improvement over what was on there previously.

Both are required to completely seal the wiper motor.

Great info, thank you. I’ll be doing this in the coming week or so and ordering from GMC Paul’s. Been trying to confirm what I needed for a while now without pulling it apart first : )

Thanks everyone. I just placed my order with GMC Paul's. I had zeroed in on them yesterday because they had the clearest description of the parts.
