@hmac300, I'm confused on what component each number is pointing to... @cadieman, I will try this later, my girl is at work right now so I can't look at it yet. and if it's a bad heater core, how hard and how expensive is that to replace?

Also, @hmac300, how hard is it to locate the vacuum line for the heater core? and how can I find out if the actuators for the heater are working? sorry, not very car literate...
