Seems like a simple question, but I can't find the answer. I have 98-02 Fbody dual fans - are they two-speed motors? If so, is it worth the extra effort to wire them for 2-speed operation, or just run them separately on high speed? (low signal turns one on, hi turns the second one on)

I just learned from a thread that I have going that f body fans lt/ls are not two speed.

They are one speed motors but are wired to run in series on low and parallel on high. Do a search for 3 relay fan wiring and you'll see how to wire them. Its better than having them both come on separately, much quieter.
