Blowing hot air after picking up from dealership?

Hi, my name is Devin. I am an auto repair expert with the Car Genius team here at RepairPal. So sorry to hear you're having trouble with your vehicle. If your Renegade's air conditioner was working fine before the engine replacement but is now blowing hot air, it's concerning that the dealership immediately pointed to a failed compressor. While it's possible the compressor failed coincidentally, it could also be related to something that happened during the engine replacement. Recharging the system might help if it's just a refrigerant issue, but a recharge won't fix the problem if the compressor is indeed faulty. You'll likely need to replace the compressor to restore proper function. Before proceeding, consider getting a second opinion to ensure the compressor is the actual cause. If you need more advice, have any other questions about your vehicle, or would like to get connected to a RepairPal Certified shop near you, we have you covered.
