Thanks Ken. On ol' Red, my '88 GL, when I turn the ignition switch to "ON"
but not to the start mode, and then turn on tne AC , the high speed fan
immediately kicks in. If I go ahead and drive it, the high speed fan runs a
while then cycles. Seems to do what is is supposed to do.

However, on the Carat, that little test does not work. The HS fan does not
turn on, period. Yet when driving, with AC off, and in stop and go traffic,
the low speed fan does cycle. Engine hasn't ever gotten hot enough to
operate the mid speed fan.

For both the engine cooling and AC on ol' Red, the fan seems to be running
properly.
