2010 Ford Expedition Sunroof

Can’t use sun roof because it is broken. How much to repair/replace or should I just seal it up so it doesn’t leak.

Just call a couple of body shops for actual prices then you can decide to repair or have the shop do a professional sealing . The price in my area might not match yours where ever you are . A Google search for sunroof might give you a fair idea of price just for the sun roof.
