I just bought a used 04' 9-3 the fuel gauge was defective (always shows empty (fuse is good) i figd it would be a fairly easy/non-imperative fix then the windshield washer fluid stopped working i checked the fuse it was good when i put it back and tried again the washer fluid sprayed for about 3 secs then stopped checked again and fuse was still good i put it back and once again it worked for few secs then stopped... finally the cabin heater blower stopped working. im at a loss any help would be greatly appreciated.

thanks,
Rick
