Hey guys I am getting a new wiper motor in my Sierra 93 hardtop. While the dash is off is there anything else I should look for or replace at the same time?

I'd advise to pull the heater box and plenum out and clean it all out, they're usually all full of leaves, mud, bugs etc and put some mesh over the top of the plenum under the cowl panel. Also check if anything is loose/rattles.

Wiper linkages from motor to wipers.

Ok thanks for that!
