Engine vibrates and pulses when AC is turned on
My 2015 Chevy Trax with 81k miles is having another issue. Whenever I turn on the cars AC, I can feel that the engine starts to vibrate and pulse when I drive around even when it’s idling. When Im at higher RPM’s, I can feel that engine begins to vibrate harder and begins to hesitate.
I’ve taken it to the dealership to get it checked out but I got unlucky. They didn’t fix anything and made the problem much worse. All they did was the change the oil and brakes.
I’ve done some research and I believe that the alternator is failing. Is that true? What is wrong with my Trax?
A failing AC compressor is pulling down the engine. @chucktobias hit the nail on the head.
