Question about 1998 Nissan Sentra
Whenever the thermostat of the acu turns on the rmp drops down
Are you turning on the compressor (as in turning on the air conditioning) or just the vent? If you're turning on the compressor and the revs drop, that's normal. The compressor is driven by an engine belt, and when it is turned on, it puts additional drag and load on the engine, causing the revs to drop.
