No windows, no radio, no gauges, no interior lights
I've found several posts online but it seems like most got lucky and simply
replaced a fuse but I've had no luck.
As mentioned none of the above work. Turn signals on the cluster do work
and flash and so do the door locks work. I've turned on the AC and it works
but did not see if it blows cold. I have checked all fuses and swapped relays
but have had no luck. One other strange thing to note is when I turn the
key to the on position there is a high pitched noise almost like a beep
coming from either the dashboard or the engine firewall(difficult to tell) for
about 5 seconds. Hoping anyone out there can help as it has been a pain.
Did the vehicle experance any voltage problems or battery replacement, did you jump anyone before this happened? If any of the before mentioned did happen then it may have caused a programming glitch in the BCM, unfortunately the only place that can properly diagnosis a BCM problem right now is a Ford dealer.
See if you can find what is making the high pitched noise. I wonder if it is a bad relay or something similar?
Update?: I removed the plastic trim to expose the wiring harness on the carpet that moves along the side to the back and noticed there was quite a bit of water and the wires were all wet. I began drying them with a vacuum and suddenly the beeping that alerts you a door is open began ringing and i immediately turned to the dash and believe to have seen the gauges illuminate right before everything suddenly turned off again. I'm not sure what to do now, I tried moving the wires and drying the rest but cannot get any response. Any advice will be highly appreciated
Sounds like your in for a strip job, you need to get the carpet up and out so you can start checking the entire wiring harness, if it has been wet a long time then chances are very high that corrosion is deeply imbedded in the wiring harness, connectors and anything else close to the floor, then there is where did the water come from, body seam, window seal in the back, could be a real problem finding.
I traced mine to the instrument panel. the connector on the left top of the panel has a preload condition. because the wire harness is too tight. it is pulling the female side of the connector off the circuit board. as a short-term fix I used a zip tie to put constant pressure on the connector.
