To be certain, you should:
* Consult a repair manual specific to your Chevy Venture's year and model. This will give you diagrams and precise locations. Your local auto parts store may have these for purchase or access to online versions.
* Use an online parts catalog. Enter your vehicle's year, make, and model into a site like AutoZone, Advance Auto Parts, or Napa Auto Parts. They often have diagrams showing parts locations.
Because working on automotive AC systems involves refrigerants that are harmful to the environment and potentially dangerous to handle, it's strongly recommended you have a qualified mechanic handle repairs or replacements of the condenser.
