Just picked up a 2001 Gas F250 4X4 XLT. Everything seems to work except for the electric windows and ABS. I pulled both window switches and cannot find any voltage on the Blue/black cables. I jumped 12v to the drivers side switch and the windows work up and down even in auto. I have voltage at the 30a circuit breaker in the PDB but nothing at fuse #7 in the PCFP. I've checked for voltage at another connector with a Blue/black cable and found nothing. I'm thinking bad cable or GEM. I have noticed that the bell system doesn't sound when you have the key in the off position with the door open if that matters.Does anyone else have any suggestions?
Thanks.

 

Check fuse F4 in the CJB. It supplies power to the rest of the accessory delay circuit relay that enables the power windows.

Also, check CJB fuses F6, F8, F15, F19, & F20 as they all supply power at various times to the GEM module which must energize the accessory delay relay.

 

Checked the fuses at the locations you listed and didn't find any voltage at window switch. Removed fuse block and Gem and cleaned connections, still no voltage. Rang out Blue/black cable from drivers window switch back to fuse block position #7. No line voltage at this location no matter what position the ignition switch is in. So I guess my next question is the GEM feeding the line side of the fuse or is there something else feeding the line side of the fuse?
Thanks.

 

you may have a bad Acc delay module in your gauge cluster
I have a bad one in my 02, need to replace whole cluster to get full functioning Acc delay to keep power to windows and radio

 

The gauge cluster has nothing to do with this circuit in this truck.

The circuit is a little bit complicated and requires going through 6 or 7 cells in the EVTM to get most of it.

Basically, the Accessory Delay Relay (ADR) in the CJB needs to be energized which supplies power from BJB CB25 to the power window and several other circuits. The fun part is getting the relay energized. The high side of the coil is supplied via an ALWAYS HOT circuit from BJB F22 via CJB F4. The low side of the coil is then grounded by the GEM (under its control) in order to energize the relay and supply power to the circuits of interest.

Check for power at the 86 terminal in the socket for the ADR. This tests for the feed from BJB F22 via CJB F4.

Check for power at the 30 terminal in the socket for the ADR. This tests for the feed from BJB CB25.

If both of those test properly, then the problem is centered on the GEM and its power inputs, the fuses that I listed in the last post. You may want to go back and check to power at each of them. They will be hot in various combinations of the ignitions switch, data I don't have at hand this morning. You might want to make a list of each of them int he possible ignition switch positions of OFF, ACC, RUN, and START. and I'll check it later against what it should be.

 

Thanks for the circuit run down. I'm going to print it out and test it tonight.
Thanks!

 

Did some testing and found the following:
ADR terminal #30 hot in any key position.
ADR relay terminal #86 never hot.
CJB F4, F15 hot in any key position.
CJB# F15,F19 only hot in start position.
CJB F8 hot only in accessory and start position.
CJB F20 only hot during starter engagement.
CJB F6 not used on this truck.

GEM # 1C3T-14B205-DC
2001 F250 XLT 5.4 4X4 ESOF

Thanks

 

That's a fault if confirmed. Check for continuity between load side of CJB F4 (removed) and ADR terminal 86. It's supposed to be a direct connection (via several connector pins and a splice). If it's open, it would explain your problem.

In addition CJB fuse F4 is supposed to supply power to the underhood lamp, the glovebox lamp, the map lights, and the vanity lamps. Do those work or not?

 

I know that the passenger side map light on the ceiling will work with it's toggle switch but the driver's side map and dome aren't working. It could be lamps so I'll have to check it out more tomorrow.
Thanks.

 

Checked for continuity between CJB4 and ADR 86 and found none but did find continuity between CJB4 and ADR 30. Hot all the time. So maybe the question is what really feeds ADR 86?

 

Power gets to ADR #86 as follows:

BJB F22 (ALWYS HOT) > CJB F4 > CJB C242a-18 (LG/YE) > Splice S229 > (LG/YE) CJB C242a-32 > ADR #86 (internal connection).

The lamps I named earlier all feed off S229 which is why I suggested checking them to see if power is at S229.

 

Thanks for the circuit list. In the hospital yesterday so I couldn't give it a look over if I feel better this afternoon I"ll track it down. Thanks!

 

Hi, Folks!

I don't mean to interfere with the diagnosis/repair in this thread, but I'm having an unusual problem that seems related. On my '05 X PSD, all the windows work EXCEPT the left rear passenger - back in January my wife started the truck, the window went down by itself, and then never moved again.

I had temporarily boarded up the window (too cold to work on it), but today with temps in the 50's I decided to pull the door panel and see if I could narrow down the problem. Couldn't find voltage coming to the window switch at all, and when I tested the window motor with auxiliary 12V power I found it worked just fine, both directions. I have since pulled the board out and raised the window with auxiliary power. I plugged the motor back in, but not the local switch (yes, I DID try it before putting the panel back on with no change). Obviously there is still potentially power coming from the driver's door, but I haven't been able to purposely move the window using either switch.

My question for you gurus is this ... is the power coming from the accessory relay broken down into individual circuits to each window? If not, I'm at a loss to explain why the three other windows all work fine while this one seems to have no power coming to it. No obvious corrosion or breaks anywhere. I was about to search for fuse box options when I stumbled on this thread. Any potential solutions would be appreciated, thanks (once you have the original poster's issues nailed down, of course)!

Regards,

 

The 05's circuitry is different.

It would be best to ask a mod to split your issue into it's own thread.

 

Appreciate the reply, but are you certain the '05 is different?

With the exception of minor sheetmetal details, it was my understanding that the Excursion carried on largely unchanged from 2000 through it's final run in '05. When the pickup trucks got the "new" dashboard and front suspension, for example, the X soldiered forward with the existing "old" equipment, largely because Ford kept planning to kill it off for several consecutive years.

I will track down the wiring diagrams for the X, but figured one of you folks might know enough about the Super Duty trucks to point me toward a potential culprit. In the meantime, if a mod wants to spin this off I'd welcome the "new view." Don't want to muddle the waters on this thread, after all.

Regards,
