Heater blower fan only has high speed
I did my search and found plenty of help.
I would like to thank everyone who contributes information. It sure helps.
I thought I'd contribute a couple pictures.
My truck ia a 1999 F150 with manual heat/ac (115,000? miles).
My fan was working on high only. With the clues from this forum, I went straight for the resistor. And look what I found...
From the amount of rust, I've apparently been missing a couple speeds for a long time. The melted plug could have been more recent and took out #3.
For a recap:
The resistor is located on the passenger side, under the dash, near the firewall. It's difficult to see.
If you look near the kick panel, you can see the wire harness and the plugs. Follow the wire to the resistor.
The two resistor screws are pointed straight up and mine took an 8mm socket. I removed mine by feel. (unplug it after you remove it, so you can see it better.)
I think prices have gone up a bit. Autozone is $57 for the resistor. I'm hoping $25 or less for each at the dealer. We'll see.

ps. I replaced my PVC hose, too. Thanks all!

I picked up the new resistor today at the local Ford dealer.
p/n 4L3Z-19A706-AA
$28.14 plus tax
in stock
They didn't have the wire harness in stock, but it was going to cost over $38.
I "repaired" the old plug and put it back together. Fan works great.

I had the same problem and bought a replacement yesterday at NAPA for $21.49 + tax. I looked it up on NAPA's website first, compared mine to the pictures on the web, found the NAPA part number (ECHBR 286)then bought it from stock at the NAPA store five miles from my house.
AutoZone quoted over $56 on the phone, said it was a special order item and I would have to pay for it in advance; screw them.

Amazing price difference. $56 vs. $28 vs $21.
Amazing that the full Ford price is half the Autozone price. I had a similar pricing thing happen with a lower control arm for my Escape.
I'm putting Napa on my "check price" list.
