i previously said that i was getting power at terminal 3 of the resistor with the switch on low. terminal 3 doesn't go anywhere. there is only one wire to the motor, red/white. it gets power on medium and high, because those circuits are complete. it does not get power on low speed because that circuit is incomplete. so the fan works fine, just no low speed because it can't get power through the resistor. the schematic of the resistor shows a complete circuit for the red/green wire to get it's power through the resistor and out the red/white wire to the motor. the real life resistor has nothing beyond terminal 3 (red/green wire). still stumped.

when I get a chance I'll pull out some old resistor packs and verify them for you

John,

looking at the pins numbered on this picture, what are your corresponding wire colors on your plug?

i'm not at the shop right now. #1 is the red/green with no continuity if i remember right.

1 Has nothing on it
2 Red/white
3 Red/black
4 Red/green

I assume you check the switch to see if the wires are connected at the switch end correctly? Just and thought
as we had a client stop in one day with a like problem (not all fan speeds) and it was not connected correctly at the switch.

they're on right. the question is, how can the red/green wire power the fan if it ends at the isolated resistor terminal?

Hey, John looking at kuehl's diagram on the plug side, the front side should look like this.

If I had a stock fan speed control (I have full variable) in my car today I could answer your question quickly. But I had a late meeting with neighbors, the Becks, last night so I'm challenge today when it comes to answering open ended specific questions.... such as "how can".

So with a fresh cup of Java, a doner fan speed pack in hand and looking at a picture Bazar01 kindly supplied and the note Rs6er posted, and assuming nothing is out 180 degrees, I would have to say that either:

a) there a possibility that your fan speed switch is defective at speed "1" (a possibility as they do fail often from carrying lots of current),

b) the fan speed switch is wired incorrectly

c) the resistor pack electrical plug has the wires mixed up

d) the fan motor is on its last legs (doubtful for the moment)

e) the resistor pack has failed (maybe but doubtful)

Is this looking at the trunk side of the firewall as opposed to the picture I took or is it just deeper in the passanger compartment?

My first picture of just the plug receptacle was looking at it from the passg. seat.

My second picture ( bazar01's marked up with numbers ) is what you would see if you had your head down in the smugglers box (evap out naturally) looking at the passg.'s smelly feet.
