1998 volvo v70 master window switch

To the "Visitor" person with " ... 1998 Volvo S70 120,000 mi where the 'master window switch' on the drivers-side door is failing ... and the mechanic wants $300."

I think that's (unfortunately) $300 is probably a fair price. I have the same problem with my driver-door master switch. In my case the rear-passenger door can no longer be controlled from the driver-door master switch. (But the switch located in the right-rear door does still work for this window.) My mechanic won't consider anything but an OEM part --- which is very expensive and constitutes the bulk of the repair price. I don't love my mechanic but he's competent and I trust him. I haven't done this repair yet --- but I probably will. The car is in great shape and has no hidden mechanical issues. But its "blue book" is about zero. Except that it's reliable and safe and good for many more years. And I only use it "around town" so I really can't justify strapping myself onto an asset investment for new car for $35,000+ or for buying a "new" Volvo. (Or for buying some used Volvo or BMW which might have some hidden mechanical issues.) So I will probably have to bite the bullet and invest about $1750 in normal maintenance (with this replacement master window switch) to keep the old beast running properly even though it will still be worth "zero" when I get through with this exercise. (This "normal maintenance " includes tires, battery, the "major" service", wheel alignment, etc.) Please give me your thoughts on this conundrum.
