Hi 914W,
As near as I can tell (so far) the POs couldn't get the front fan to work, so, instead of cleaning the slider switches, they just by-passed the top slider and put in an after market, non-cool-looking switch in the dash. They cut (in order to by-pass) two wires, brown and (looks like) white....and currently I can't figure out where they came from or where the other ends are (that were cut).
Does anyone have a picture of this slider switch unit...with wires attached?
Thanks for any help, Ross
