Free auto & mechanics tip: Fresh air, then recirc, then a wet windshield wipe (step 12 of 12 from "Wipers, Washer Fluid & Cabin Filter").

Start the car. Fan on 3, fresh air (not recirc) for 30 seconds — you should get more volume than before if the old filter was packed. Recirc on: the flap should click and the air smell a little more like the cabin. Musty smell that was there before may linger a day; a soaked evaporator is AC disinfectant or a shop, not another filter. Replace the filter every 12 months or 20,000 km / 12,000 miles, sooner on dirt roads.

You passed when both new front blades lock on and clear a wet windshield without a grease arc, both washer nozzles spray, the bottle has climate-right fluid (no dish soap), the cabin filter arrow matches the old direction, and the glovebox opens and latches without a cracked tab. Write the blade lengths in the manual so you do not guess in two years.

You'll need

  • Blades click and wipe clean
  • Washer fluid correct, both jets work
  • Filter arrow correct
  • Glovebox latches

Pro tip: Rear wiper, if you have one, is a separate length and often a different clip. Same smear logic. Same 'do not let the arm hit the glass.'
