Air and water leak at windows on 1995 celica convertible

Replace the weatherseals that are located above the side window and above the windshield.
Aftermarket weather seals for convertibles can be bought from Lynn Steele Rubber co or Softseal co.
You might try a tip that I have used in the past. If the weatherseals have shrunk to the point where there is a gap where they used to meet, it can be closed.
Buy urethane adhesive like is used to install windshields.
Put it on the ends where the gap is present and cover it with plastic wrap so it only sticks where you want it to. Close the top and leave it closed for 24 hours while the urethane cures. Open the top, remove the plastic and trim away any excess.
If the weatherseals are not too badly deteriorated, this works about 75% of the time.

Yeah, the old worn out rubber seals needs to be replaced.... but you wont be able to get the exact OEM ones. Have to play around with after market ones or get a liquid rubber spray to mold on torn edges or reshape...

Renew the hood and rubber seals
