Hey I need some help. I was driving in a heavy thunderstorm when alot of things stopped working. I don't really think I was stuck by lightning, but the list of things that stopped working is strange. Before I took this trip, I was having issues with the liftgate latch staying locked, no rear wiper and not license plate lights. My remote locks worked, but not as good as they did before. I think it is in the wires that flex in the hinge, but I have not found one broken so far and I have not had time to work on it. I did not want the hatch to stay locked on me so I unplugged the hatch lock actuator, which meant the rear hatch would always be unlocked. I taped the plug so I am pretty sure it did not short out.
Now back to the big problem. Below is the list of things that went out all at once while driving at highway speed.
All gauges except tach and speedo went to full left.
6 warning lights came on the dash. Airbag, ABS, low fuel, some weird picture of the wheels and driveshaft with a wrench and I forget the other two. (not the check engine light)
Radio went dead, no lights no sound.
All windows, locks, etc that are controlled on the drivers door and passenger door went dead.
Oddly the rear windows work from the rear door controls (power mirrors still work)
The heating/ac display looks normal, but the a/c no longer works. Blower still works
The display no longer shows the transmission gear selector. It shows the letters PRND... but the gizmo that shows you what gear you are in is gone.
The digital display for things like gas mileage, oil change and such now are blank. Like for the oil life it shows __%
The cruise control is dead.
Their is probably more not working, but that is all that I noticed.
What I know that still works.
I was 100 miles from home when this happened. I was concerned the charging system might be dead too, but everything seemed ok from a voltage standpoint for the whole trip home, so I think the charging circuit still functions. (no voltmeter to tell with)
I was afraid to shut the envoy off till I got home, but the starter works and it starts right up.
wipers and headlights work. (good thing, I needed both to get home)
I have checked both fuseboxes and don't see any blown fuses. This problem seems to be involved with so many functions that I figured somebody would know what could go out or what fuse/relay that could blow to cause this many malfunctions at once.
This is on a 2005 Envoy xlt awd 4.2 with 100k. I have owned it 9 years and it has not had any previous electrical problems. (no hacks in the wiring and everything did work on it)
Thanks in advance for any help.
