Start at top front corner with forked pry after removing door handles and door pulls Most clips are hidden behind door closer around wheel arch and unable to be removed. you may have to make long sharp bladed chisel style tool to cut plastic plugs between door card and metal. Remove inner felt seal and should be able to get coat hanger modified to pull inner door wire leading to locking mechanism

The inside door latch may have been broken. If it's the rear doors, check the 'child lock' switch. It may be set at ON. It is usually located at the door latch on the inside. Check your user manual on how to activate/deactivate.

I believe your car has a full frame windows? If that is correct then are you talking about the rubber the window glass slides up and down in? If so, then you have to remove the inner door panel and might be helpful if you have power windows remove the power window switch from the inner panel and reconnect to wiring harness. Using this technique, there are 2 10mm bolts holding the window glass to the regulator. Position the glass with the 10mm bolts through a couple sight holes, remove the 10mm bolts but hold on to the glass so it doesn't fall in the door and break. install the rubber window channel and reverse procedure.

Water on the floor board in the back seat is usually caused by a leaking rear window, or leaking back glass...you will need to remove the inner rear door panels to confirm the exact leak...(as long as it is warm enough:) after removing the door panels...you can ask a friend to help...run water from a garden hose over the outside, and continue until you see the location of where the water is coming from...if the rubber seals on the top or bottom of the doors are bad...this certainly allows the rain (water) to come inside...Nice Car and worth fixing...:)

I'm sorry, can't contact with your chat request because I having other question open; I suggest check this proceduro for GM Camaro/Firebird 1993-1998 Repair Guide...
