The Volvo's use an ignition switch that feeds power directly to the accessories. Probably wear is causing an intermittent connection. We own 3 Volvo cars right now, and all 3 have had the same issue. For the 740's, it's a pain in the butt to replace. The 850 is a 15 minute job. Pull the black plastic bezel from under the steering wheel, 4 Torx T-15 screws, and switch is right there. Switch is $60-$75 depending where you find it. FCPGroton or IPD are your best bet. Good Luck- PRM
