    I have the same problen with my 2004 trailblazer. all lights work with the execption of the low beam, cannot figure out the problem

    WOW!
    I'm totally on this sight looking for a solution to a completely different problem, but I JUST GOT THAT ONE FIXED!
    ...On My '04 Trail-Blazer it was EXACTLY How You Described!
    Even my High-Beams Worked! (Much to the aggravation of ANYONE in the On-Coming Lane!) *Sigh*

    Happily, The Problem was RESOLVED when, after 2-Days of work, the
    Mechanic "Cleaned" the area in the Fuse-Panel, (Under the Hood), that
    apparently Powers the Low-Beam Headlights!
    The Whole-Deal Cost Me
    $40.00, But I gave the Mechanic Twice that for the Frustration!
    ...Turns-Out This is a Common Problem because of the Semi-Exposed
    Fuse-Panel Under the Hood!
    Hope that You Experience Similar Results, But MAKE SURE THE WHOLE-ENTIRE FUSE-PANEL IS CLEANED THOROUGHLY!!!
    (The
    Problem I am Currently Dealing-With is Apparently Resulting from THE
    SAME INITIAL SOURCE, and it involves my Transmission, which could
    end-up costing Me MUCH, MUCH, MORE!

This is, in fact, correct. The problem you're describing I just repaired. The problem is a relay in the fuse panel. There are two identical black relays, one for the headlights on/off function and the other is for the fan clutch. Please do not just swap one for the other, if your headlights are not switching off and swapping these relays appears to solve your problem, this would indicate that the initial relay is faulty and needs to be replaced. Operating your vehicle with a blown relay in the fan clutch's fuse panel will result in your vehicle eventually overheating. The part cost me about $40 from my nearest Chevy dealer and was easy enough for any novice to replace on their own.

Sounds like the contacts in your switch are going bad. The switch in your high-low beam lever is extremely hard to get to as the steering column will need to come out, if it's the style I recall on a 97. The switch you may be able to find on the web somewhere because if you get it from ford it may be pricey. You will probably need to take it to your local service center to be replaced.
