Question type: Maintenance & Repair

my volvo guy ordered an ignition switch and its a dual air system, when I turn the switch
on and off it goes off. I read on some of your answers you may think it a fan going bad or
some kind of module. at the volvo shop they quoted about $170 for the module. What do
you think?

...personally one must look at the age of the battery...and the condition of the main connection to the ground....disassemble the lug (1/0) cable off the battery....wirebrush it clean and the territory that it bolts to....with a solid ground...(as dis-similar metals form a "semi-conductor" layer of corrosion there) and a NEW battery, you problems WILL go away~

My friend at work has a '93 Cadillac Eldorado that does the same thing. Has been for years. Nobody, including the Cadillac Dealer can figure it out. I kinda remember reading somewhere that certain years and models of BMW will do this as part of the ventilation system. Maybe it's normal? -Jim
