my car RPM idling reading is about 7000 but when my car aircond is ON, when the radiator fan start moving, the reading is fluctuate from 7000 to 10000 RPM untill the radiator fan is off & back to normal RPM and also when I OFF the aircond.
is't due to the compressor problem because it was intermittent problem which not always happen?
Need expert advice.
