My vehicle was recently in a accident involving a raccon (go figure) and did a lot of damage. I already had it checked out and they said it needed alot body work and possible wheel alignment. However this morning I kept hearing a clicking sound when I turned my windshield wipers on and it would immediately stop when I turned them off. I even tried pressing on the brakes when going at fast speeds and at low speeds but no clicking. I was wondering what this could be and if it may be serious.
If there was any damage to the hood or the left side front quarter panel it could have bent a cowl or some other shroud near your wiper motor or wiper connector arms (hidden under the cowl at the bottom of your windshield). If it's a small interference it could be "clicking" past it rather than totally being stuck.
Try running the wipers without the engine on and get outside to locate the sound more precisely.
