My 2006 PT Cruiser has a broken windshield wiper nozzle. I thought it would be an easy repair so I bought a new nozzle from the dealer. When I tried to remove the broken half from the tubing, it broke again leaving a portion of the stem in the tubing. It's deep inside, so nothing to grab onto to pull it out. If I could just get the piece out I could insert the new nozzle and the job would be done. Anyone have a suggestion? Thanks much.
