2002 Cadillac Seville Q&A

2002 Cadillac Seville Question: What causes the Air conditioner to blow black greasy foam out of the vents?

The A/C works fine except that it now blows black greasy foam out of the vents everytime it is in use. What causes this and is it worth fixing? -

Only thing i can think of is system oil leaking from evap. core, if it is greasy, but should also be leaking out onto the ground as well. It's worth fixing if you need AC and in SC. i bet you do! Have the ac drain checked! -
