I'm not sure why you had "*textVehicleName*" If it can work, it should simply be
<a4j:support event="onchange" reRender="textVehicleName"/> If that doesn't work, it probably can't be done with a4j and JSF 1.2. I'm fairly certain I did something similar back when I was using the Richfaces 3.3 a4j and JSF 1.2.
