F250 WINDOWS,WIPERS,CRUISE,4WD SWITCH NOT WORKING

2000 Ford F-250

Electrical problem
2000 Ford F250 V8 Four Wheel Drive Manual 215K miles

These accessories have progressively quit. I have replaced the GEM, multifunction switch, and the fuse panel. I have looked in the harness for obvious shorts. I traced out the wires as much as possible from the switches to the fuse panel. I can't find a common denominator. The windows work until it blows the fuse. The 4WD switch does not have juice. I am unable to figure this out. How can I find the problem without completely dismantling the wiring harness?

Have a look at the grounds under the kick panels on both sides. What # fuse blows?

Thanks For responding. The fuse that keeps blowing is #15, a 5 amp I think.

OK #15 is a 5 amp and it has the GEM, instrument panel and BOO(Brake on off switch) Try unplugging the BOO at the brake pedal, and the cruise deactivation switch on the master cylinder, or brake lin under the master, see if the fuse stops blowing then.

I unplugged the BOO switch and the fuse has not blown yet while operating the windows and using the brake pedal.

The accessory delay relay, once engaged, would not quit until the window reached the bottom, even when interrupted by the switch. That or something else has either burned out my window motor or created some other problem, making the driver's side window inoperable. I did shuffle relays to check. All the same. Passenger side window still operable.

What's next?

There is also a relay for the one touch for the drivers window, but replace the BOO and see what happens, did you disconnect the deacivation switch?
You may need to have it scanned for codes, even if the dash light is off you may have " B" codes stored, the truck has a DDM(drivers door module). Last, have you replaced any light bulbs lately? I will get back on this at 2: 00 pm After work, test you door window switch.

I have not had time to get parts. I will replace the BOO switch if necessary.

My Chilton diagram does not show a drivers door module; only an accessary delay relay for the drivers window. Since I disconnected the BOO I have not blown the fuse. The passenger window works. I have not yet unhooked the brake pressure switch (cruise deactivation).

I forgot to mention that my ABS light has been on since I lost wiper function. Also, I have not replaced any bulbs.

I greatly appreciate your knowledge and your
help.

This can be the switch in the drivers door causing at least the window issue.

TEST C: DRIVER-SIDE WINDOW INOPERATIVE
1. Using New Generation Star (NGS) tester, retrieve Diagnostic Trouble Codes (DTCs). Perform Generic Electronic Module (GEM) self-test. If no DTCs were retrieved, go to next step. If DTC B1405 is retrieved, go to step 13. If DTC B2357 is retrieved, go to step 16. 2. Turn ignition switch to RUN position. Using NGS tester, monitor PID D_DN_SW while pressing driver-side window switch to DOWN position. If PID value does not agree with switch position, go to next step. If PID agrees with switch position, go to step 6. 3. Turn ignition switch to LOCK position. Disconnect driver-side window switch harness connector C510a. Turn ignition switch to RUN position. Using NGS tester, monitor PID_D_DN_SW. On Crew Cab and Excursion models connect a fused jumper wire between driver-side window switch harness connector C510a terminals No. 6 (Tan/Light Blue wire) and No. 2 (Light Blue/Black wire). On Regular and Super Cab models, connect a fused jumper wire between driver-side window switch harness connector C510a terminals No. 3 (Tan/Light Blue wire) and No. 4 (Light Blue/Black wire). See Fig. 3. If PID indicates DOWN when jumper wire is connected and OFF when jumper wire is disconnected, replace driver-side window switch and retest system operation. If PID does not indicate DOWN when jumper wire is connected and OFF when jumper wire is disconnected, go to next step. 4. Turn ignition switch to LOCK position. Disconnect fuse junction panel connector C242b. On Crew Cab and Excursion, measure resistance in Tan/Light Blue wire between driver-side window switch harness connector C510a terminal No. 6 and fuse junction panel connector C242b terminal No. 10. On Regular and Super Cab models, measure resistance in Tan/Light Blue wire between window switch harness connector C510a terminal No. 3 and fuse junction panel connector C242b terminal No. 10. See Fig. 1 and Fig. 3. If resistance is less than 5 ohms, go to next step. If resistance is greater than 5 ohms, repair open in Tan/Light Blue wire and retest system operation. 5. Remove GEM. See GENERIC ELECTRONIC MODULE under REMOVAL & INSTALLATION. Measure resistance in Tan/Light Blue wire between fuse junction panel connector C242b terminal No. 10 at relay panel side and GEM connector C240d terminal No. 8. See Fig. 8. If resistance is less than 5 ohms, replace GEM and retest system operation. If resistance is greater than 5 ohms, replace fuse junction panel and retest system operation. 6. Turn ignition switch to LOCK position. Disconnect one-touch down relay from fuse junction panel. See Fig. 4. Test one-touch down relay. See MINI ISO RELAY under COMPONENT TESTS. If one-touch down relay is okay, reconnect and go to next step. If one-touch down relay is faulty, replace one-touch down relay. 7. Turn ignition switch to LOCK position. Disconnect left front window motor 2-pin harness connector. Measure resistance in Orange/White wire between left front window motor 2-pin harness connector and ground. If resistance is less than 5 ohms, go to next step. If resistance is greater than 5 ohms, go to step 11. 8. Turn ignition switch to LOCK position. Turn ignition switch to RUN position. Using New Generation Star (NGS) tester, set active command ONE-TOUCH DOWN to ON. Measure voltage in Orange/White wire between left front window motor 2-pin harness connector and ground. If voltage is less than 10 volts, go to next step. If voltage is greater than 10 volts, go to step 10. 9. Disconnect one-touch down relay from fuse junction panel. Disconnect fuse junction panel C242a connector. Measure resistance in Orange/White wire between fuse junction panel connector C242a terminal No. 24 at relay panel side and one-touch down relay terminal No. 30. See Fig. 5. If resistance is less than 5 ohms, replace GEM and retest system operation. If resistance is greater than 5 ohms, replace fuse junction panel and retest system operation. 10. On Crew Cab and Excursion models, measure resistance in White/Black wire between driver-side

Scan for codes and even the electrical shorts should set a code. No DDM in your truck. Sorry!

I may be overconfident, but I'm pretty sure the motor died in the window. It hasn't been real strong since I've owned it. At this point I'm interested in trouble shooting the cruise control and wipers. I replaced the multifunction switch even though I wasn't confident that was the problem. They went out when I was replacing the GEM. I put the old one back to see if the new GEM was the problem. No change. Can't find any additional damage to the under dash wiring. Any ideas?
