Ok having trouble with a truck I just bought. 4x4 dash lights do not come on for any reason. Not even at key on. 2003 F250 Lariat ESOF.

Checked relay and fuses.... 4x4 works, but no dash light.

Took it to dealer who said it was a problem with the gauge cluster. They wanted $800 to replace it with another one. I went in and picked up the cluster, sent it to Circuit Board Medics who tested it. They said the gauge cluster works fine and they got the 4x4 lights to work with their scan tool.

Dealer says they tried their scan tool to command them on, could not get them to work, so they thought bad cluster. I think that logic is flawed because if something is bad preventing the lights from coming on, hooking a scan tool up to it wont turn them on either.

So right now I am $220 in labor with the dealer and $130 into circuit board medics for shipping and testing. And still don't know what's wrong.

I called the dealership to tell them the cluster is good and the female service advisor seemed a little offended. I'm considering taking it somewhere else.

 

The sector position switch (PN F81Z-7E440-AA) activates "4X4" indicator lamp in the cluster. It is located on the transfer case (pass side on the front half of case near the top)
Hope this helps you.

 

Thanks! Looks like I can pick one up for $27 bucks from Toulsey. Do you know how difficult it is to install? I live in an apartment with no garage. And is this connected to the shift motor on the tcase or something different?

 

It thread in the top side of case . Looks almost like an oil press sensor. Not on the elec motor side closer to the vent on top. Should be able to do it in driveway, just be careful you dont snap the elec connector. Its only plastic.

 

So I will have the cluster back tomorrow.

I asked the dealer if they tested that switch. They said yes and have power and ground all the way to the cluster.

ugh... the company I sent the cluster to had no problems getting the 4x4 lights to work so I tend to believe them, and think it is a problem with the truck.

I'm going to try and replace that switch and hope for the best. Could it be anything else?

 

I put that part number into Toulsey Ford which says it has been superseded by BC3Z7E440A. I gave that number to another Ford dealer to buy it locally and they said it was a transmission temp sensor ???

 

Go there personally to the parts desk and tell them it's the sector position switch and htye should bring up the IPB. Tell them where it is located on the diagram and see what it comes up as name and number wise.
