    Thanks to everyone who has been so helpful in the past. Being I'm a 35
    year old Volvo newbie, balancing trying to restore this car, while
    playing husband and daddy to a 5 year-old boy, I wish there was more
    time in the day to tinker with cars.

    Now that my 1987 740 GLE engine seems to be running well, it's time to
    start working on the finer things. I have to decide whether to convert
    from R12 to R134 and with that being said - try and figure out why I
    don't get much blow from the vents. I mainly get hot air.

    I've read up in the Haynes manual, and (after I get a new ignition
    switch), need to check (drum-roll.......) vacuum!

    I see there are a few vacuum motors in the dash?????? Is this right?

    So -- here goes. Vacuum leaks seem like a needle in a haystack for me,
    so if anyone can start pointing me in the right direction I'd be much

    Where to check under the hood?
    Where in the cab?
    What would prevent the flaps from not making more air come out the
    vents? My blower motor does make a little rumbling, so I'll change it
    to be sure.

    So, the question "del dia" is where are the many vacuum locations I
    should check for my air conditioning well-being?

    Many thanks!
