So my lever broke on the heater switch and the correct one with three wires was 50 - 100 dollars! I ordered a BL2 BWD $16.99 from Oreilys and is a good replacement. I cut off the unneeded extra terminal. bent the connections of the other to 45 degrees and it plugs right in. its has more positions than needed but high and low speeds work just fine.
