However, here's a *general* outline of the process. The specifics might vary slightly depending on the exact model and any modifications:
1. Safety First:
* Evacuate the refrigerant: This is absolutely crucial. You'll need an AC recovery/recycling machine to safely remove the refrigerant from the system. Releasing refrigerant into the atmosphere is illegal and harmful to the environment.
* Disconnect the battery: This prevents accidental shorts.
* Wear safety glasses and gloves: Sharp edges and potential refrigerant exposure necessitate protection.
2. Accessing the Evaporator:
This usually involves:
* Removing the dashboard: This is often the most time-consuming part. It requires removing various trim pieces, screws, and possibly even the steering column (partially or fully, depending on the specifics of your car). Reference a detailed shop manual.
* Disconnecting the HVAC components: This includes blower motor, various ducts, and potentially the heater core (depending on proximity). Take pictures or make detailed notes as you disconnect everything.
* Accessing the evaporator housing: Once the dashboard is partially or fully removed, you'll need to locate and access the evaporator case, usually located behind the dashboard.
3. Removing the Evaporator:
* Disconnect all lines and electrical connections: This includes the refrigerant lines, drain line, and any temperature sensors or other electrical components connected to the evaporator.
* Remove the evaporator case: This often involves removing bolts and clips securing the case. Expect some tight spaces and potentially difficult-to-reach fasteners.
* Remove the evaporator core from the case: Once the case is removed, carefully remove the evaporator core itself. This is a delicate component and should be handled with care to avoid damage.
4. Reassembly:
Reassembly is the reverse of the disassembly process. Remember to carefully reconnect all lines and components, ensuring tight connections to prevent leaks. Have your AC system recharged with the correct amount and type of refrigerant by a qualified technician.
Essential Tools:
* AC refrigerant recovery/recycling machine
* Socket set (various sizes)
* Screwdrivers (various types)
* Pliers
* Wrench set
* Shop towels
* Vacuum pump (for system evacuation after reassembly)
* A complete 1995 Corvette repair manual (highly recommended)
Again, this is a complex process. Unless you have extensive experience working on automotive HVAC systems, attempting this repair yourself is strongly discouraged. The cost of professional repair will likely be less than the cost of damaging your car and/or voiding your warranty on the system. A professional will have the right tools, knowledge, and experience to do the job safely and efficiently.
