Q: When my AC is on and while stopping it rattles and shakes

asked by on

When my car is stopping and AC is on, it rattles and shakes. At first I thought it was a motor mount and got one of motor mounts replaced. But now it seems if it is getting worse than better

My car has 184000 miles.
My car has an automatic transmission.

Hi there.

In many cases a faulty air conditioning compressor will cause excessive drain to be put on the engine and cause the symptoms you’re describing. The best way to diagnose this is to complete a pressure check of the AC system. If you have the right equipment, complete this test sooner rather than later; as it can create additional damage to the engine if not repaired. If not, contact a local mechanic who can come to your home or office to diagnose your A/C system and replace your A/C compressor if necessary.
