Does the heater have anything to do with a blown head gasket on a 1998 Oldsmobile Silhouette?

The heater generates heat by blowing air over a small radiator type device (heater core) under your dashboard. The device runs hot coolant through it continuously. If you have a blown head gasket, your coolant is being evaporated trough the firing chambers and tailpipe. When the coolant level is low due to evaporation, there is no water to flow through the heater core.
Keep in mind if you are not certain that this is a blown head gasket, these models were notorious for a defective lower manifold gasket leak that caused it to lose coolant the same way a head gasket would.

Can you explain a wet front floor on a 1996 Oldsmobile Silhouette not clogged AC drain and not bad heater core?
It is quite possible that a wet floor on a 1996 Oldsmobile Silhouette is caused by a leak in the body that allowed rain water to get into the passenger area. Window seals and the seals around the front firewall could have been damaged enough for this to happen.
Heated seats not working in Oldsmobile silhouette?
A very common cause for heated seats not working is that the heater element has burned out on either the cushion heater element or the seat back element. The way the system is wired, if one goes bad, neither will work.- techJK ----------------------------------------------------------
Olds Silhouette is overheating but there is no heat coming from the heater A repair person says the head gasket is leaking but would that would explain the lack of heat?
Our 2000 Oldsmobile Silhouette was doing the same thing plus we'd get low coolant indicators every 3 or 4 weeks. I went nuts almost trying to find the leaking coolant. It turned out that it was misting it's way out of the intake manifold gasket located on the top of the engine on the drivers side. You might see a small puddle of coolant on top of the block. Apparently it's a common issue with those engines.
