V8 Climate control questions...
 

The climate control in my 1990 V8 only blows hot air, and i know the freon is charged. So, I pulled the climate control codes and am getting a 09; coolant temp sensor:open circuit, and also 16; High pressure switch F118 has open circuit or cycled at least one time during current driving period.

So my question is this; since i dont have access to a bentley manual, how do i find these 2 sensors, and what should i be checking them for once i find them?

thanks
