98 Blazer Problems--MFS??

I have had numerous electrical problems with my Blazer. The most current are; Drivers side window rolls down but won't go back up, Floor vent does not work, Turn signal noise goes off at random, wipers won't turn off or won't turn on, trip odometer resets itself to 0 after turning vehicle off.

Just from reading through the forum it seems like this could be the cause of a few things, the Multi Function Switch, Wiper Circuit Board, and Vacuum Lines. Is it possible to buy a MFS? I have looked online and haven't found one, I have also heard that it might be possible to set off your airbags while installing it. It sounds to me like all these minor annoyancesare goign to cost me plenty.

This vehicle has been more of a headache than anything....I can't wait until I can sell it!! Please give me some sites for the products mentioned or some do-it-yourslef tips to resolve these problems!! Thanks!

i would go and if it is insured i would light it on fire
