I turn the air conditioner in my car begins to shake

Asked by GuruW6LMJ May 24, 2018 at 07:30 PM about the 1990 Pontiac Grand Prix 4 Dr STE Sedan

Question type: Maintenance & Repair

1 Answer

The A/C creates additional load on the engine. If there is a check engine light address that first. Does the A/C blow cold air? If not the compressor may be failing internally. On a vehicle this old it may not be cost effective to repair the A/C system.
