fan question
i installed my own manual fan switch and i spliced into the blue wire, which is the high speed fan. when i turned it on, i noticed that only one of my fans is working. is this because one fan is the high speed fan and the other is the low speed fan? or should they both turn on regardless of which speed its on?

You have to splice into both fan relay control wires, because of the way the relay system works. Grounding the high speed wire is going to result in high speed for the RH fan only (just like the OP found out).
