    I don't really think so on this one. With the ignition switch, it is either off or on, from my experience. I have never heard of it going off and coming back on in the middle of driving it.

    I would rather point to a loose wire or connection somewhere. And something like that is really hard to pin down.

    I would start at the fuse panel and make sure everything is tight and clean.

    I had a similar problem with my 2000. The blower worked fine on high but would slow on the other settings then quit all together. I replaced the resistor pack but it still didnt work. I found out my blower was junk also. After replacing both the resistor and the fan it worked fine. The resistor pack is located behind the glove box mounted on the firewall. The foreward screw is impossible to remove. I unplugged it and mounted the new one with velcro to a flat spot under the dash.
