The 1992 Bonneville doesn't use a cabin air filter. Ensure there is no debris or leaves in the area around the windscreen wiper panel.
Had one of these loved it traded on 2k ssei wish i still had it. your problem isa leaking evaporator-it gets coatedw/ a/c oil which traps al the dust and dirt if you remove the blower motor resistor you can clean it w/brakeclean and shop air or a small brush.
I took off the blower motor, and got a long nose air blower on my compressor, and stuck it in there, and blew it out...helped...stuff on the windsheild/hood gets sucked in there...
