The low pressure valve on a 93 Chevy Corsica is under the hood. It is on the larger hose coming off the AC air compressor.
The AC system can be recharged in a 1990 Chevy Corsica by connecting a refrigerant tank to the low pressure inlet. Refrigerant is then added until the correct pressure is reached.

hood up right front of motor i think That would be the condensor. AC Evaporator is inside the dash on the passenger side.
Compressors going bad on the AC <-- NO not probable. Maybe the blower motor going our or a relay or sensor
The AC evaporator is located in the lower Dash.
To replace the AC evaporator core in a Chevy Venture, start by disconnecting the battery and removing the dashboard to access the HVAC unit. Then, drain the refrigerant and remove the necessary components, including the blower motor and any ductwork. Once you can access the evaporator core, unbolt and remove it, then install the new core and reassemble everything in reverse order. Finally, recharge the AC system with refrigerant and test it for proper operation.
By removing the lowerr dash on the passenger side. This is a tough job.

To charge the AC on a Chevy Corsica, first, locate the low-pressure service port, which is typically found on the larger diameter AC line, usually near the compressor. Attach the AC charging kit to this port, ensuring the connector is secure. Start the engine and turn the AC to the maximum setting, then follow the instructions on the refrigerant canister to add refrigerant until the system reaches the proper pressure. Always check for any leaks and ensure the system is not overcharged.
To remove the AC evaporator coil from a 1998 Chevy pickup, start by disconnecting the battery and draining the refrigerant from the AC system. Next, remove the dashboard and the HVAC assembly, which involves detaching various components like the heater hoses and electrical connectors. Once the HVAC unit is accessible, unbolt the evaporator coil from its housing and carefully extract it. Reassemble in reverse order, ensuring all connections are secure and leak-free before filling the system with refrigerant.
