How do you get to the expansion valve on a 97 LSI?

To access the expansion valve on a 1997 LSI (likely a Chevrolet model), first, ensure the vehicle is turned off and the AC system is decharged for safety. Remove the glove box and any necessary panels to reach the HVAC unit. The expansion valve is typically located near the evaporator core, which may require further disassembly of the HVAC housing for full access. Be cautious with any refrigerant lines and electrical connections during the process.
