    here you go:

    function yesnoCheck(that) {
    if (that.value == "other") {
  alert("check");
        document.getElementById("ifYes").style.display = "block";
    } else {
        document.getElementById("ifYes").style.display = "none";
    }
}
    <select onchange="yesnoCheck(this);">
    <option value="">Valitse automerkkisi</option>
    <option value="lada">Lada</option>
    <option value="mosse">Mosse</option>
    <option value="volga">Volga</option>
    <option value="vartburg">Vartburg</option>
    <option value="other">Muu</option>
</select>

<div id="ifYes" style="display: none;">
    <label for="car">Muu, mikä?</label> <input type="text" id="car" name="car" /><br />
</div>

    Check out: Display div if a specific select option value is selected

    Also don't use ID use data attributes or value to check comparison.
