I picked up an 03 Liberty Renegade two days ago. So far I like it a lot. I just have a quick question. The dealer mentioned the sunroof assembly was bad, and needs to be replaced. I'm ok with that. However, i've noticed the sunroof is in the "vent" position about 1/4 of an inch. Is there a way to close this securely so the sunroof is totally sealed? Thanks in advance guys!!
