| Don't quote me, But I think you have to remove the whole dash board to get to the blower motor and resistor. I'm sure someone with a little more info will be along shortly to correct me if I'm wrong.

| Welcome to the Blog!!!!
Sounds like the Blower Switch to me....
Should be easier to remove and to test.
Any way:
The Blower Motor Resistor could be in one of 2 places....
The Older Trucks, that I'm used to it is on the Passenger side of the Firewall under the Hood near the Blower Motor. It a plate held on by 2 screws. it can be removed from under the Hood
The Second place would be under the Glove Box on the "Vent work" for the A/C heat...It may be closer to the center of the Dash (radio Area)
I fixing to leave right now, but if you can not still find it, give me a holler and I will check out the Tech Web site and get the exact location for ya
Good Luck with it | |

| Same thing happened to my '97 F150. The blower resistor is probably rusted and the contacts have separated. You don't have to remove anything to get to it. It is behind the glove box. You have to get right up under the dash with your head against the floor and look up. It is held in with 2 screws. It's tricky because you can't see it while trying to unbolt it. You basically have to do it by feel.
I got a pic, but it's even hard to back enough to get it.

| Sportruk --
Thanks for the pix. It's the part I thought...on the bottom of the A/C plenum, right? I'll give it a try. I think the part can be bought for under $20. I've been told it's an AC/Delco #15-50635.
I was using a trouble light and a mirror the other day when I thought that I had located the resistor, so I should be golden as far as getting it out. I'll let you know how I make out.
Thanks again for the help.

| | How did it go? I hope you don't have to rip the dash out to get to it. Its either that or the heater core you have to, and to quote one of the Ford mechanics at my old place of employment, "Somebody outta get fuckin' sued over that shit." | |

| Ya, they sure messed up the design for ease of heater core changing. In my '88, I can change it out in 1/2 an hour.
I'm sure the resistor is the problem. Mine was rotted apart.
When you put the blower switch on HI, it sends a negative feed directly to the blower motor, bypassing the resistors. When it's switched to the slower speeds, it sends the negative feed though the resistor set to regulate the speeds.
To change the resistor, it makes you wish a 3 year old kid was able to swing a wrench. | |

| Yup, you are understanding it correctly.
I don't know if that part number is correct or not.
I went to the Ford dealer for mine. The Ford part number is 4L3Z-19A706-AA. It cost me $38.80 CND so it will be a little cheaper for you down there.

| | After a quick search, all I could find was, that Delco switch #15-50635 is actually the heater switch for the overhead consoles in the Expy and Navigator. | |

| | Does this mean that I could pull the part and still use the heat on high without causing any problems? I figured that once it's out, I could leave it out 'til I install the new part, no? | |

| | It's no problem at all to remove it and run it on HI. That way you can take it with you and make sure you get the right on. | |

| Sorry I didn't post after I replaced the resistor block. Took about 5 minutes in and out. I used a mirror which made it a lot easier than trying to get at it directly, which is pretty much impossible.
The Ford part number is 4L3Z-19A706-AA, just like Sportruk said. It cost me all of $15.78 including tax. A high school buddy of mine that works at a dealership parts department hooked me up. I called around for pricing at different Ford stores, and the part went for $22.00 on the average and as much as $30.00 at one clip joint! Jim's list was $17.52 but he sold it to me for $14.89. Jim's dealership is about 15 minutes away, but it was worth it to see an old high school friend and get the part so cheap.
Thanks again for everybody's help.
