Having problems with your Oldsmobile Cutlass Ciera ?
A mechanic said that the interior air filter (a foam pad) which is in the dashboard is dirty and clogged. His repair would cost $600-$700. Symptoms: greasy film on inside of windshield, smelly air, poor heater and AC air circulation. I'm planning a 2000 mile trip in July and have some time to try to fix this.

The heater core regulates the temperature inside your car.
Sounds like it's a case of bad heater core. Check the coolant level and monitor if you are losing coolant.
It is suggested to replace the heater core.
