i recently aquired a 1995 sts and this morning i noticed some small amount of water on the inside of the rear window. i have a sunroof too. could that be leaking? im lost. and i have some codes i dont understand. p 103, p 065, s015, s036, s044. can someone please help me figre these out? thank you

 

I too have water inside the rear window in the right conditions and I think it is from my trunk leaking. Lift up your spare tire and look to see if the carpet is wet.

I have sealed all the joints in the trunk with seam sealer but I think my water comes from the 3rd brake light area, I just haven't had time to check.

By the way I have a 98 sts, sorry I can't help with the codes.
