I used a jumper wire to bypass the low speed coil and the second speed came on when I turned the lows speed on. So it deffinetly is that.

Could also be the switch in the dash, mine only worked on high speed. Switch has burned up due to a failed blower motor resistor
Below is copy and paste from my thread
one of the things that bugged me when i decided to take on this project was that the fan had one speed, and no A/C. Pulled the dash parts boxes i had from the 4runner shell i had.
Found a good fan switch with the a/c controls and started to pull apart the dash. *
i was very happy:toilet3::wtf: to find evidence of a short

the new 4 speed switch is on the left and the one speed on the right, you can see some melting on the right switch

sure enough,the old switch had shorted for some reason in the past..probably the quality stereo install work*
Attachment 110823
evidence of the quality that went into the stereo install, wiring from the Goodwill...

i hate leaving a project in this state but ran out of time

upside is now i have all fan speeds and working A/C
went ahead and replaced the blower motor resistor today.
I'd like to have a talk with the genious at Toyota who decided to put a failure prone point in such a convience place (tucked under the blower unit on the right side)
I went ahead and pulled the glove box hoping for a little more room.

got it out after a few minutes and cussing, not the easiest thing to get out.
if you need to having a 7mm wrench helps on the back screw/bolt, you can get to the visible screw with a screwdriver or nut driver.
new one on the left, old one on the right..old one was slightly tarnished.
new one should offer a few years of good service
