Leaking back sunroof, order new rubber seal, how

How bad is the leak? A 'Factory Fitted' sun roof will usually leak for a few common reasons. It isn't closed properly, (Yes I've done that!). The drain channels are clogged and full of dirt so the water is pooling up in the runners and leaking in. The seals are starting to fail. On a 05 plate the rubber seals will probably be the factory originals so will be old and may have started to go bad so the sunroof isn't watertight anymore.
Your first option is give the rails and sliders a good clean. Open the sun roof to it's widest and give the runners and the channels a heavy duty clean. An old toothbrush, toothpicks and cotton buds are great for getting into the troublesome areas. When clean lubricate the moving areas with Silicone Grease.
Standard types of Grease or Lithium Grease are Petrolium based so can be bad for rubber seals, Silicone is mineral based so doesn't damage the seals.

Do you have heat ? Water leaks or engine coolant?

If all above ok

you have dirt on the water channel of sunroof if got one.

OR

clean dirt under the windsheld wipers there is a rubber hose that drives water from the windshield bottom to the engine.



Open hood and look back to the wall you ll see a black rubber pipe its not circular its like a V

Can't fix anything till you find out where the leak is

Get inside & have someone run the hose on it

Remove whatever trim you have to,to see the water

most upholsterers should be able to help here If not go to a rubber dealer that sells sponge rubber etc as most have a good selection of auty trim rubbers that you can fit yourself. The best glue is loctite 406 Be careful as it is a super glue

Hi, Most likely, if its leaking, its done for. I have never heard of "cleaning" a gasket. Usually the oil and heat make the rubber compound hard or deformed causing the leak. You can order a new one online at rockauto.com or JC Whitney. You will need to order it by vehicle year and engine size.

Check for a drain hole around the sunroof and spray the rubber with spray can silicone spray to soften the weatherstripping so it will be easier to seal

hopefully is not after market sunroof, if it is, your in trouble. factory sunroof replace rubber seal is the only way to fix the problems

lift rubber edges and apply clear silicon sealant under edges let cure hose with water to test, if leak then seal edges of glass with eurothane sealant, not silicon will rot in sun within year
