Fresh Air Cable

[Romer]

My Fresh air cable doesn't work (never has). Poking around I found it tied to another cable and it was disconnected (by PO). The FSM manual didn't give me any info. The Haynes manual shows it connecting to the to the bottom of the blower motor (makes sense). Except I can not find any connection points where the diagram shows it goes. Do I need to remove the blower motor to find it's hook up point?

Another issue I have is the blower only works full on, Everything looks cabled right. I am guessing problem with the switch, but since it works full on, it's no big deal and not worth replacing the switch. Any other guesses to what it might be?

Thanks,

Ken

There is a vent door on the firewall side of the blower motor. You remove the air box and you can see it in there. There is a post that the cable attaches. There is also a mesh cover that the cable must pass through.

I bet it is your switch but IIRC the resistor on the blower does somthing with the 2 levels.

Thanks David. Your not the tard Bailey says you are.

If you only have high on the blower the resister is most likely blown (it gives the low speed by cutting the current to the blower motor). Use a test light to see if current is getting to the resister then check and see if it's making it out (doubt it...BTDT). If it is getting to the resister with the switch on low the switch is fine. If it's not getting through the resistor then you found your problem. If it is going through the resistor than that leaves the motor or the motor wires...

HTH!

He's good at hiding it.

I had the same problem w/ my heater, apparently it's relatively common. In my case it was the resistor being buggered.

Check out this link:

In my case, it would've been like 30 bucks to ship those tiny parts up to Canada, so went to cruiserparts.net and found this: (on the used parts page for FJ40)

"Blower Resistor any $75 If your motor only has one speed, you will need to get a resistor
74-84

$25 New aftermarket resistor set up. "

I think that info from the ccot server should make it to our tech page- this topic comes up every few months.

Woody? Whaddya say?

And to think I could have just brought this up at the club meeting and have Jeff tell me in person.
