Q: Whenever I switch the fan on my 2009 Honda City, the headlights momentarily dim. Is this normal?

AAA: When the fan comes on, momentary dimming can be expected as the electrical system compensates for the additional current requirement. But regardless, it is a good practice to have the batter inspected during the service and trickle-charged if required, but not too often as it may reduce battery life.
