I need to have my heater core replaced in my 1994 Pontiac Bonneville. Just wanted to get some tips/advice or maybe a site that could help me out. And how difficult a task is this? Does the entire dash have to come out?

They charge about four hour's labor. Doesn't look like a novice job. Unless your a do it yourselfer when it come's to car's.
You have to remove Instrument Panel (I/P) assembly plus
REMOVE OR DISCONNECT

1. Drain cooling system.
2. Heater hoses from heater core, using J 37097.
3. Air mix valve actuator. See: Air Door Air Door Actuator / Motor Service and Repair
4. Retaining screws and heater core cover.
5. Retaining screws and heater core from vehicle.
