I had a clogged driver's side washer nozzle which I removed and blew compressed air into to clear it (2014 Frontier S, 4-cylinder 5-speed). It works fine now but my windshield wipers stopped working once I put everything back together. I've replaced the fuse but that didn't fix it. Here's the odd part....if I manually move the wiper blades up they stop about half way up the windshield. When I flip them on they suddenly slam down and won't budge, then about 10 seconds later they unfreeze and I can manually move them again. That tells me it's not a fuse problem. Could I have bumped something when I took off the cowl? Thoughts please? Thanks.
