Hazard warning signal switches on without being activated

If the above-mentioned vehicles are found to have a problem with the hazard warning signal switching itself on without first being activated, the cause may be a defective hazard warning switch.

(Figure 1 / Figure 2 taking a Lancia Musa as an example)

Figure 1

An internal defect in the hazard warning switch triggers the activation of the hazard warning lights without the switch having been operated.

Repair notes:

We recommend the following procedure

  • Remove heating control panel of the manual temperature control.
  • Disassemble the heating control panel
  • Replace/renew hazard warning switch (Figure 2)
  • Assemble heating control panel in reverse order

This defect can also occur in other vehicle models that have identical components!
