Amps drop when heater blower is turned on ?
Have a problem with my 98 Z71 K1500 Silverado . Amps drop on gauge when I turn on the A/C Heater blower .Alternator is new . Shut off radio and other controls and when blower starts the amps drop from 14 to about 10 .Can hear blower motor running and it has no noise and operates at all the speeds . What would cause the amps to drop when I turn on the A/C heater blower ?
