NAPA may call it that, but...that's not what FoMoCo refers to it as.

D3TZ-19706-A .. A/C Blower Motor Resistor Assy-3 terminals / Use with factory installed Integral A/C or Hi-Lo Vent System.

Applications: 1973/79 F100/350 & 1978/79 Bronco.

 

I looked that part up on Napa and that's a generic relay sure enough. I wonder if it's used on earlier model trucks with AC only.

 

Bill

I think the reason NAPA does not refer to it as a Resistor may be because it's not one. We are looking at two different parts, the part number i posted is a NAPA number-ECH AR235Relay.
Ford # D2LB-14C690-AA and if i remove it my blower stops, because i have one does that mean I have a Camper Package ?
Thanks

 

NAPA gave me the Ford part# D2LB-14C690-AA and they called it a blower motor relay for my app but it is generic and has many other apps.
See ND's post showing it as a Saftey relay, maybe to protect the blower switch? I also have the Resistor that he looked up.
I think 79F150400M needs the same relay.

 

FoMoCo does not refer to the above as a "blower motor relay."

NOTE: D3TZ-19706-A is not a safety relay, it's the blower motor RESISITOR. See post #16.

 

Yes. That's it!!! You even gave me the NAPA part number. That's excellent. In the Chiltons manual they call it an "accessory safety relay".....so I think we're on the same page here.

 

FYI
Bill, "AKA NumberDummy" posted this in another thread, I guess Ford liked this handy little relay, the member that started this thread needed it for his A/C. Check out the price from Ford! There is a OEM NOS on ebay now for $19.99. Happy to help.

Marked with ID engineering number E9TE-13853-AA = Ford part number: E9TZ-13853-A .. Horn Relay & Bracket Assy.

 

I am new to this Ford thing and very impressed with the service I have had from my old truck. (shoulda got a ford sooner) this truck is (door tag) listed as 8800 gvwr. I am retired now and must keep it operating at a low cost. The chance to "strip" as much as I wanted from a 91 150 XLT was given to me so with tools flying I got a lot. not sure what crosses to my 90 F250. but I would like to have your input in the future ... you came recommended by many on FTE !!!! Thanks Dave. (former Hac.Hgts resident)

 

Sorry about the "hi-jack job" , but I haven't found Bill's posts on that site . this whole thing (including the truck) is fairly new to me ... and I'm old too ...ya that,s it !!!! Again sorry about the hi-jack ... Dave

 

You'll get the hang of it. It take a little bit but once you figure it out you open up a wealth of ford knowledge.
