* Labor costs: This is the biggest variable. Labor rates differ drastically by location (rural vs. urban, geographic region) and the specific shop (independent mechanic vs. dealership). Expect to pay anywhere from $100 to $300+ just for labor. The job is fairly involved, requiring the dashboard to be partially or fully disassembled.
* Part cost: The evaporator itself can range from $100 to $300 or more, depending on the brand (OEM, aftermarket). You'll likely also need to replace the expansion valve and potentially the drier/accumulator to ensure a clean system. These additional parts will add to the overall cost.
* Refrigerant: The system will need to be evacuated and recharged with refrigerant (R134a in this case). The cost of refrigerant and the service to recharge it will be an additional expense.
* Unexpected issues: During the replacement, mechanics may discover other problems with the AC system, like leaks or other failing components, adding to the final bill.
Therefore, a reasonable estimate for the total cost to replace the evaporator in a 1998 Dodge Ram 1500 would range from $300 to $800 or more. Getting multiple quotes from reputable mechanics in your area is highly recommended to get a better understanding of the price in your specific situation. The high end of that range factors in potential unexpected repairs and higher labor rates in certain areas.
