gmrulz4u Posted July 12, 2006 Report Posted July 12, 2006 Whenever I turn on my AC or Heater in my 89 Cutlass Supreme I get what is almost the same as alternator whine through my speakers. I don't know if it's the alternator or the blower motor? What should I check? Grounds? THANKS! Quote
Brian P Posted July 12, 2006 Report Posted July 12, 2006 I've had factory amps go bad and this would be a symptom. I'm including the "internal" amp aka the upper part of the factory radio. But first definetly check over grounds and check the connections at the blower motor, climate control, and radio. Quote
gmrulz4u Posted July 12, 2006 Author Report Posted July 12, 2006 Yeah right now there's not even a radio or any radio exquipment in the car... Quote
Garrett Powered Posted July 13, 2006 Report Posted July 13, 2006 take the amp out too if its still in there. Quote
Brian P Posted July 13, 2006 Report Posted July 13, 2006 Do you have the bass gain switch on the dash? If so, you have an extra amp under the dash. Just an FYI Quote
