I remember seeing someone on the forum who swapped their wiper arms for some earlier ones, since ours don’t stay in the held up position, while cleaning the windshield etc.. I seem to recall ‘99-‘02 wiper arms stay up. Can anyone confirm? Thinking about doing this since I need to paint them anyway.
There is an interesting story with the wipers. Initially one could fix them in the "UP" position, but GM started to receive waranty claims that the wiper arm scratches the paint on the hood, since it very close indeed. So, in their infinite wisdom, instead of reshaping the arm (like it is on GMT900, for example), they decided to slightly modify it so you basically can't lift it up. I believe in the later production time they switched back to the older version.
Anyway, I went to a local slavage yard and found the ones that could fix in the upper position and installed them. I also picked TWO driver side arms, instead of 1 driver & 1 passenger. The difference is that driver side has 2 nozzles to spary washer fluid, and the PASS has only 1.
Also, as far as I am aware, there are 3 designs of wiper arm:
1. You couldn't even lift if more than a couple of inches from the glass.
2. You could lift it vertically, but it wouldn't stay in that postion.
3. You could lift it up and it would stay in UP position.
