resistor dryer or accumilator?

Sorry to be a newb question, but I'm just learning heating and A/c in my class. I have to give a demonstration with my car this week about my a/c components and stuff.
Does the tib have a resistor dryer or a accumulator? and where is it located?
Also was wondering if anyone knows where I can find a diagram for the tib with the a/c components to show where it is located or picture or something to help me get an idea
i didnt know if it was under the fender or behind the firewall or what

Thanks=]
