It shouldn't be difficult to fix. Having said that, I have no way of knowing your mechanical skills or what is in your tool box You will need to remove the wiper arms and the cowl panel (the plastic part that the nozzles are mounted in). The nozzle part number is 20820073 and the Dealer will want $15.92 for one. If you calculate shipping, you probably won't get it much cheaper online.
Replaced the nozzle the other day. No problems at all, didn't even take anything off. Just popped a few clips near the nozzle and there was plenty of play in the plastic shroud to lift it up and connect the new nozzle to the hose.
