Help! Horn doesn't blow and a few other things

[rodyvette]

I bought a 1999 Corvette FRC a few days ago. Nice car, but there are a few things I need to address. First, the horn doesn't work. Where is it located and what are the typical things I should check? Next, the driver door, the glass is a little loose between the door and the door panel. Like someone has constantly shut the door by pushing on the glass, it is just a little loose or floppy between the door and the door panel. Is there a fix for this? I have this same problem in my 85 vette, the glass is floppy and haven't been able to get it tightened up. Finally, the wheels are Asante wheels and the sensors don't work. Can I turn off the indicator so the dash doesn't display that message? Cool car, the guy had cold air intake, headers and 3" exhaust and a cam installed. Really gets fun in the higher rpms. Oh, the 6 speed is retarded to shift. It is not smooth and easy to shift gears. The shifter is real tight and it's easy to hit 2nd instead of 4th when downshifting from 5th or 6th. Any common solutions to make shifting quicker and easier? The guy had installed a Hurst shifter. Thanks for reading and helping. Rody
