A/C Evaporator Core Guide for the 2013-2020 Dodge Grand Caravan
Losing your A/C? Here’s what you need to know before replacing the evaporator core in your Grand Caravan.
- These vans often have two evaporators; the rear one fails more often and is much cheaper to fix. Diagnose the leak location first.
- Replacing the front evaporator is an expert-level job requiring full dashboard removal. The labor cost will be much higher than the part cost.
- Due to the high labor cost, using a cheap front evaporator is risky. A failure means paying for the 10+ hour job all over again.
- When replacing the front evaporator, also replace the heater core and expansion valve to prevent future repairs.
Is Your Front or Rear Evaporator Failing?
Before you buy any parts, you must find out which evaporator is leaking. Most 2013-2020 Dodge Grand Caravans with rear climate controls have two evaporators. There is one in the front under the dashboard and a second one in the rear passenger-side quarter panel.
The rear evaporator is a very common failure point on these vans. It sits behind the rear wheel, where road salt and moisture cause it to corrode and leak refrigerant. Always have a mechanic diagnose the leak's location 🎬 Watch: How to check for a large A/C leak on your Caravan before assuming the front evaporator is the problem. Replacing the rear unit is much easier and cheaper than the front.
Symptoms of a Failing A/C Evaporator
A bad evaporator core will stop your A/C from working. Here are the common signs:
- Warm Air from Vents: This is the most obvious symptom. The system can no longer cool the air effectively.
- Hissing Noise: You might hear a hissing or gurgling sound from the dashboard or the rear cargo area as refrigerant escapes.
- Sweet or Musty Smell: Leaking refrigerant can have a slightly sweet chemical smell inside the cabin. A musty odor can also develop from mold growing on a malfunctioning core.
- Compressor Won't Turn On: The A/C system has pressure sensors. If enough refrigerant leaks out, the pressure will be too low, and the system will prevent the compressor from engaging to protect it from damage.
- Oily Residue: A/C refrigerant contains oil. A technician may spot an oily, sometimes greenish residue (if UV dye was used) near the evaporator drain or connections, indicating a leak.
Choosing the Right Aftermarket Evaporator
Replacing the front A/C evaporator is one of the most labor-intensive jobs on your Grand Caravan. A shop will have to remove the entire dashboard to get to it. Because the labor cost is so high, the quality of the part you choose is critical. You do not want to pay for this job twice.
Pro Tip: Replace More Than Just the Evaporator
While the dashboard is out, it is strongly recommended to also replace the heater core and A/C expansion valve. These parts are in the same HVAC box and require the exact same labor to access. Replacing them at the same time is cheap insurance against another massive repair bill down the road.
For this vehicle, you will find brands like Four Seasons, Global Parts (GPD), and Spectra Premium. Here’s an honest breakdown:
- Premium Aftermarket (e.g., Spectra, Four Seasons): These are well-known aftermarket brands. Forum discussions show mixed but generally acceptable results for many users. For a part like an evaporator, where fitment is key, these brands are often a safer bet than less-known, budget options. Some users have noted minor differences, like the quality of included foam seals, compared to the original part.
- Standard Aftermarket (e.g., Global Parts): There is less brand-specific feedback available. Some users have reported issues with components from budget-tier brands failing prematurely.
The Bottom Line: For the front evaporator, the risk of a cheap part failing isn't worth the savings. The labor to replace it again would be over $1,000. Consider a premium aftermarket brand or even an OEM Mopar part. For the much easier-to-access rear evaporator, a quality aftermarket part is a more reasonable choice.

Frequently Asked Questions
Is replacing the front A/C evaporator a DIY job?
For the front evaporator, this is not a recommended DIY job for anyone but an expert mechanic. It requires removing the entire dashboard, steering column, and HVAC assembly. The rear evaporator is more feasible for an experienced DIYer, as it involves removing interior trim panels in the cargo area.
🎬 See this walkthrough for replacing the rear A/C evaporatorWas there a recall for the A/C evaporator on these vans?
No, there have been no recalls for leaking A/C evaporators on the 2013-2020 Dodge Grand Caravan. There was a safety recall for 2008 models where an HVAC drain could leak water onto an airbag module, but this was not for a refrigerant leak.
My A/C is blowing hot on one side and cold on the other. Is that the evaporator?
This is usually not the evaporator. This symptom is often caused by a failed blend door actuator or a software issue within the HVAC control module. A Customer Satisfaction Notification (R62) was issued for 2014-2015 models to reprogram the HVAC module for a related issue.
Can I just block off the rear A/C lines if the rear evaporator is leaking?
Kits are sold for this purpose, and it is a possible workaround to avoid replacing the rear evaporator. However, some shops report poor results with these block-off kits, with a high failure rate. It may also reduce the overall cooling performance of the front A/C system.
