Hi:
If it is coolant, then the heater core is leaking, so we have to confirm that. As far as the blower motor, it is possible something is getting wet if the core is leaking.
Now, my next concern is the noise you are hearing. Does the vehicle ever over heat? Often times a gurgling noise can be the result of air getting into the cooling system via a bad head gasket or it could be getting hot enough (overheating) to boil the coolant.
Here is a link that explains how to check for a head gasket issue. One section discusses seeing air in the system. If you can, follow the link and let me know what you find.

I will watch for your reply. Please note that if the heater core is leaking, the coolant should be getting low in the system. When the engine is cool, remove the radiator cap and see if the radiator is low.
Take care,
Joe
