I just bought a used Lexus & am wondering how to fix some minor issues. Here's my info: SC300, 2000, 110000 miles 3 owners listed on CarFax Bought for $8000 in Roseville, Ca Just bought yesterday! Now for the issues: Passenger door lock won't lock/unlock via remote or driver's auto-lock button Radio Antenna won't go up Trunk won't open via remote Driver's door is a bit "jittery" when opening When starting, there is sort of a thud/knock right before the engine starts, but very smooth to drive overall. Not sure if this is normal or a potential issue. Also, no manual so I'm not sure how to work everything!! Anyone have easy solutions to fix some of those, or are any of those something that I should take to a shop?
