Electrical Problems Galore!

[mtinal]

Howdy folks,
Even though I am new here I was a good boy and looked through many old threads trying to find some answers to my problems with no luck. Hopefully somebody can get me on the right track.
I am having some freaky electrical problems in our 2004 Pilot EX-L (139k miles) and they all have cropped up in the past few months. at almost the same time. Cruise just stopped working (it is not a fuse), heated seat works intermittently, am Radio doesn't work (buzzing sound), headphones stopped working (buzzing sound), door actuator went out, 2 headlight bulbs have blown, reverse lights flicker (along with dash indicator), volume adjustment on steering wheel works intermittently, etc, etc.
All of this has happened within a few months after many years of trouble free driving. Any thoughts? I have replaced the door actuator by the way but I am clueless as to the flurry of problems I am having. There are no aftermarket accessories installed by the way and I have checked the battery connections. With so many things hapening at about the same time I would guess it is a global problem of some sort (ground or voltage reg maybe?).
Thanks for your time and any suggestions would be greatly appreciated.

Not sure why you posted in this section, but anyhoo.... how many years of service has your current battery seen? If it's still the original one, I'd suggest getting a new one. A weak battery causes electrical chaos with the Pilot.

Have the battery and alternator checked for problems.
Has your Pilot ever been in deep water? Water can easily total a car.
Don't care about headlight bulbs. If you use silverstar bulbs rather than the cheapest type of halogens, those things have a lifespan not much longer than a candle.
Cruise: Most CC systems rely on vacuum to set the throttle. If a vacuum pipe leaks, the cruise dies.

Start looking for evidence of mice having adopted your Pilot as a home over winter.

If the battery was weak enough to cause those problems, I highly doubt the vehicle would even start. On my Pilot when it had it's original old battery, just leaving the map light on for 30 minutes would drain the battery enough for it to not start. However, no other issues such as you describe. Nonetheless, batterys only last 5-6 years and if you have the original Honda battery, replace it. I cannot see how these differing systems are directly and specifically related. I hate to say it, but it could just be coincidence due to mileage and age. However, I would check the voltage at the battery with the vehicle running and make sure it is around 13.5 volts. If more than 13.5 bolts, then perhaps the abnormally increased voltage could blow things out? Just a theory.

Have you considered the possibility of rodent damage to wiring under the hood? Mice, squirrels, etc., often seek refuge under the warm hood when it's cold outside. Once there, for whatever reason (nesting, food), the critters can find the wiring attractive.

Agreed. Disconnecting the existing battery for 20 seconds will probably solve your 'ghosts' for now, but a new battery will solve it for years.

Without a reboot, things will get worse. 'reboot battery Honda' would be a good one to Google.

Remember HAL in the Sci-Fi movie 2010 ?
