Install

  1. Clean the area where the foam pad of the humidity and temperature sensor circuit board contacts the windshield with an isopropyl alcohol (IPA) wipe, and then allow the area to dry before continuing.
    Caution:
    Make sure the windshield is completely dry before continuing, the foam pad will not stick if the windshield is wet.
  2. Peel the tape from the new humidity and temperature sensor circuit board, and then install the circuit board on the windshield bracket.
    Note: Slide the connector end of the circuit board under the tab on the windshield bracket, and then press the hole on the circuit board onto the alignment pin of the windshield bracket.
  3. Use a PH00 (Phillips #00) screwdriver to install the screws (x2) that attach the humidity and temperature sensor to the windshield bracket.
    Torque 0.12 Nm
