Has anyone replaced the wiper arm pivot pin does it just pull out or is there a certain trick too it thx

 

What exactly are you referring to as the wiper arm pivot pin??? If you are referring to the pivot point at the wiper arm connection to the transmission, I doubt that is replacable... If that is where you are having a problem, the wiper arm itself will need to be replaced...

 

its hidden wiper arms so there's a bolt connecting it to the transmission and there's also a pin that connects the pivot arm to it thats what I am tiring to find out if its pressed in or fastened some other way

 

Depending on whether GM wanted you to replace it, they either used a fastener, or punched in a pivot pin of some exact diameter and swaged (i.e. bashed or pressed) the end to make it stay in place.

If swaged, a dremel can help cut the end of the pin off, at the risk of damaging whatever you’re cutting the pin-end out of. Then you’ve got to find a replacement exact-diameter pin, cut it just a little too long nick an X pattern into the end and swage the new pin into place.

Pictures woudl help, but perhaps these notes will be enough.
