Check for a loose or cracked vacuum hose that activates the dampers to move air up to the windshield.

1993 Cadillac Fleetwood Brougham. It has a rough idle?

Question edited for clarity.
Question moved to Brougham category.

The 'let's try replacing this' method of car repair seldom works and is expensive. Your vehicle has an OBD port and although limited due to age and technology, there should be enough information that a professional scan tool computer can diagnose the issue.

Just want to know if the 1999 deville cadillac is fronmt or real wheel drive

All Cadillac Deville models are FWD (front wheel drive) after 1985. The only RWD models made were the 85-92 Brougham, 92-96 Fleetwood Brougham, the 97-02 Catera, the 2004+ STS and 2003+ CTS.

I am a girl with a 1985 cad fleetwood brougham and the air flow for defost is not working and i get steam coming out .Is it a heater core? karen

if it is sweet smelling steam, it is a leaking heater core. They are hard to get to. If a small leak, add a can or bottle of stop leak to the radiator or coolant reservoir.

The no air flow to the defrost ducts is confusing since, by law, the system is desgined to fail to defrost if there is a system problem, like a vacuum leak to the heater controls.

Sounds like you have 2 issues. Is the coolant low in the radiator and overflow bottle?

report back.
