Clearing of openings for a water drain


  1. Below at channels of a door and in elements of rigidity of a frame of the bottom of the car regularly clean openings for a water drain the brush for a tube. Quite often these openings are corked with dirt or anticorrosive substance.
  2. Then check both branch pipes of drains of water below in "the moistening box" between a windshield and a motive compartment. Here dirt can accumulate.
  3. In the car with a sliding roof in addition check roof opening drains (see above).
  4. For a clearing – ahead from above, behind from below – the old cable of a speedometer approaches.
