The heater will blow cool air for 20-30 min before getting warm, we have replaced the blower motor but are wondering about the resistor or heater fan switch. What do we need to check or replace?

Actually, if you are not getting heat, it isn't any of the things you mentioned. I need you to test something. WIth the engine on, hot, and the heater on high, feel both heater core hoses. Both should be hot.

Let me know what you find. Also, let me know if the engine is running at a normal operating temp.
