4. Peace of Mind: Purchasing a new AC heater housing gives you peace of mind knowing that the part is under warranty and that you won't face any unexpected repair costs for an extended period.
Cons of Buying a New AC Heater Housing:1. Cost: New AC heater housings can be quite expensive, especially for older models. The high cost might not be feasible for some enthusiasts, especially if they are on a tight budget.
2. Availability: Finding a new AC heater housing for an older Squarebody truck can be a challenge. You might need to contact dealerships, specialty parts suppliers, or even import the part from overseas.
