During a heavy snow and cold period, front windshield wipers would not work. Some short sound under the hood after switching on the wipers and then silence. Wipers will move an inch up to 3 but no more and then reset after power switched off. Tried to tighten the wiper arm nut and was somewhat loose, didn't solve the issue.

Re: Front windshiled wipers not working
The only thing left to try, other than replace the arms is, take those nuts right off & remove the arms. Take a small wire brush, or whatever you can find that will work and clean the splines on the pivots, and inside arms as much as possible, re-attach arms & tighten. If the metal is stripped away too much inside arm, they may have to be replaced, either from a wreckers, or new. There are some compounds out there that they say work, to add metal, but in my experience, they weren't all they were cracked up to be.

sounds like the connecting rod between both wiper arms either broke or one of the keepers popped off under the connector for that arm..since the wiper system IS NOT designed to wisk snow off the window once accumulated, this can an does happen.. even seen motors get burned out doing this..cleaning the window first will save this issue and the equiptment. need to acess this arm<take off the vented peice below the windshield and everything should be visible there..repost findings
The windshield wiper circuit has an circuit breaker in it, under heavy load this breaker trips to protect the wiper motor, when the motor cools, the breaker resets automatically restoring proper wiper action.
when you turn the wipers on do you hear any sound? If so, then you may have disconnected a ball joint in there behind the firewall - typically the top (black) panel (under the wipers/ at the back of the hood) comes off or you could find other access to inspect more thoroughly to be sure. If no sound, test the power to the wiper motor with a test light, if no power, check fuses, wiring, ground, etc., Best regards Ck
If the wipers were buried under snow/ice or frozen to the windshield, you may have blown the red 10 amp fuse located in cavity 9 in the fuse block located on the bottom left side of the instrument panel near the parking brake pedal. In order of easiest to check: 1) ensure wipers not frozen to windshield. 2) ensure wiper arms are not loose on the pivot stud, 3) check the red 10 amp fuse. You stated that "you can hear the motor". Which motor do you hear? The engine or the wiper motor? If you hear the wiper motor, then the fuse is alright. Try 1) and 2) above. PT Stanley
