I’ve replaced all grommets along the rear lower windshield and had also taken the steps of adding some silicone around each one to ensure of no water leaks. I am still getting drops in my trunk right in the center. Could this be the wiper seal? Is there a part replacement for just the rubber gasket? I’ve only been able to find the full wiper arm and if that’s the case, I’ll delete the wiper entirely.

 

Wiper mounts inside the rear windshield. You'd have leaks on the rear deck lid above the rear seats. Inspect your trunk seal or have someone watch inside as you spray the outside of the car.

 

Thanks, it’s been raining so I’ll check on the next clear day. Does the wiper use a rubber seal though? In case I want to replace that while parts are still available.

 

There is a gasket but I'd imagine it's hard to find. If regular Lancers have rear wipers you may be in luck.

 

I wonder if it’s able to be bought separately .

 

Everything has a part number, finding it available is the hard part.
