Hello I have a 1987 Cavalier Z24 when using air condition the condensation backs up in the car. The drain is not stopped up where the panel bolts into bottom of air box. Whats even worse I have a 92 Cav Z24 does the same exact thing. Doesn't matter home many times you take it down seal it put it back in with in two days its running the fire wall inside. PLEASE HELP !
Rust, the firewalls on these cars are thin and rust through easy.. have a bad drainage design...
Mine is basicly shot on both sides, just slow it down when it gets too bad...
