new componentid;

for (new i; i < 14; i++)
{
    componentid = GetVehicleComponentInSlot(GetPlayerVehicleID(playerid), i);
    if (componentid != 0)
        RemoveVehicleComponent(GetPlayerVehicleID(playerid), componentid);
}

That should do it.
It checks every component slot for a component-id.
If there is one installed, componentid will not be 0 and the component will be removed from the player's vehicle.
