Fiat Idea / Lancia Musa - Hazard warning signal switches on without being activated | HELLA
Idea / Lancia Musa
Model year 2003 -2007
All models with manual temperature control
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)
An internal defect in the hazard warning switch triggers the activation of the hazard warning lights without the switch having been operated.
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!
