Volvo XC90: Heater and Defroster
Affects Volvo XC90 · 2007–2008 — about 2K vehicles.
The hazard
On certain vehicles, the Climate Control Module may receive a "Shut-down signal" from the Engine Control Module (ECM) after ignition key insertion. If this condition occurs, the climate control functions will not be available (including defroster) during that driving cycle. This can decrease the driver's visibility under certain driving conditions and cause a crash with personal injury or death. Correction: Dealers will install an ECM software update.
