where is the heater core in a 1994 buick park ave?

Look under the hood. On the fire wall you will see two rubber hoses , attaching to brass fittings, going into your car. inside behind it,is usually were a heater core is. If it is leaking check for damp carpet. It will be in that area. Since summer is coming up shortly, you can just turnit off under the hood. Or have it by-passed for now. A heater core replacement in any vehicle ,is alot of trouble . And no fun at all.
 
Raise the hood and look for the two heater core rubber hoses where they hook up to the heater core behind the firewall on the passenger side of the engine compartment. Also look up a new heater core on http://www.autozone.com and click on installation instructions, location etc. You may find the the whole dash has to be removed to replace the heater core. It's a $600 job on many model cars.
