    Anyone have simple instructions on how to upgrade the Climate Control
    switch for 1993 volvo 850.
    There was a change made and all the replacements require an update.
    One method is to use a jumper wire to get power from the alternator.

    Exactly how is this done.

    Thanks in advance for any help.
