Two problems related to hazard flashing warning light switch have been reported for the 1998 Volvo S70. The most recently reported issues are listed below.
Repeated failure of headlamps, selector switch (lights go out), and turn signal. I need to continuously apply pressure to the selector switch in order to keep the lights on - this makes driving unsafe.
Poor visibility behind vehicle. Hazard light switch is inappropriately positioned in front of the automatic shift handle, and is accidentally switched on. Remote control for the rear trunk is over-sensitive.
