Heater core how to replace heater core on 1995 cadillac fleetwood brougham

"I need all the BELT diagrams for my 1983 Cadillac fleetwood brougham. There are 4 different belts. And the car has been sitting for 3 years. So I wanna replace the belts." ****** yall must cant read? ****

is your car running at normal temperatures? possibly bad heater core. the flaps that direct the air flow in the vents may not be working properly. and has it always had this problem you may want to see if someone has bypassed the heater core there are two coolant lines going into your firewall right next to each other. sometimes when the heater core goes bad people will do this to get by but if youve had heat before than this off course would not be the problem

i have a 1995 fleetwood brougham and when you open the doors inside lights dont work neather does any of the in side light work with doors closed even the ones on the mirror

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.

Answer
follow the fuel line under the vehicle, on the driver side between the back tire and the front door.

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