so, I was being careless with my windshield wipers when there was ice on them and now the one on the driver's side broke loose. its still attached and all, just whatever the mechanism is hooked up to is either broken or off track. is this going to be something as easy as replacing the mechanism that controls it? or will it be something more complicated that I should take in to a shop? I'm driving an '06 tacoma. tried to see what exactly was broken, but just from looking under the hood and not taking anything off, I couldnt see a difference. any help would be appreciated.
