Recently I just got my car running again in 8 months. When I first started it, I had a problem with the wiper linkage binding up or scraping against the cowl and blowing the fuse everytime I started the car up and ran the wipers. So after figuring out the wiper was the cause of the blown fuse, I made sure to lube the linkage with some wd-40 and graphite mixed together and applied with a toothbrush to each linkage joint. I worked the linkage back and fourth several times, pushing it at each end as far as it could go and reinstalled it. Now the wipers feel like their on speed!
Not sure what was the biggest help but:
Added a 1 gauge batter cable over the winter, cleaned the fuse box contacts, and lubed the wiper linkage, brown wire surgery. Just some suggestions.
