Q: My A/c makes the engine shudder and some squeaking is coming from the hood. Same when the fan is on the defrost setting.

asked by on July 07, 2017

When i turn the A/C on, it makes the engine shudder in 10 second intervals and some high squeaking is coming from the alternator or compressor? Same when the fan is on the defrost setting. And the cabin lights dim in time with the hazards when they are flashing. Could it be something as simple as the serpentine belt failing?
