If the condenser cooling fans fail to turn on, the AC will often blow warm, particularly when the vehicle is idling and lacks natural airflow.

WrenchConnect diagnosis signals
A leak in the AC system can result in low refrigerant, preventing the system from absorbing heat and cooling the cabin air.
Leaves, dirt, or road debris can block the fins of the AC condenser at the front of the vehicle, restricting the airflow needed to cool the refrigerant when the car is not moving.
The AC compressor may be wearing out and failing to pump refrigerant efficiently at lower engine speeds, though this is less common on a relatively newer vehicle.
The answers suggest the 2015 Honda Accord should be checked by a shop that handles brakes work.
A rock or piece of debris caught between the brake pad and rotor can cause a grinding sound, though it usually doesn't cause severe vibration.
Common failures often come from worn service parts, loose components, leaks, low fluid, or weak electrical connections.
Rotors that are warped, heavily scored, or damaged from metal-to-metal contact will cause significant vibration in the steering wheel or pedal, along with grinding noises at higher speeds.
The compressor or its clutch may not be engaging properly, preventing the refrigerant from circulating through the system.
The brake pads may have worn down to their metal backing plates, causing a grinding noise and vibration when pressed against the rotors.
