Hi- I'm in New Zealand, which means no quick trips to the local Chevy junkyard for parts for my '87 Blazer. The wiper switch has (I think) quit. Not only is sourcing a new or gently used one here tough, but it looks like a major drama to replace. Has anyone out there got any suggestions? Use an aftermarket switch and dash mount??? My wagon has had cruise control, but now doesnt- but the switch is still there on the stalk. Is it possible to use that for the wiper, rewiring on the firewall or somewhere to avaoid a teardown?? Help!
