I read the forum weekly but rarely post unless something has me stumped. Always got a winner for you guys an y'all have always provided an answer that works!

Got a 2008 Acadia SLE w/208k, all in all it's been a decent car, looks new, has a junk yard tranny, motor is decent, doesn't burn oil and gets good highway mileage. I do most of the work myself but with three back surgeries and no lift, I am limited.

Anyway, that's the preamble, my wife drives the car, she backed it in the garage tonight and noticed the park sensor didn't come on. When I checked it I figured it was a bulb but I pulled it up on the DIC an it was turned off and wouldn't let me turn it back on. Still figured a bulb but as I went further I found the drivers power seat didn't work, the garage door opener didn't work, and the seat heaters no longer work. Passenger power seat works, seat heaters don't. Checked fuses, everything seems fine, no blown ones. It's got me scratching my head to say the least.

Could it be a relay, something with the DIC, a gremlin? I can see the power seats/seat heaters maybe connected, higher amp but throw the other two in an I would think low amperage. Plus it's weird, they did it all at the same time, everything else in the car seems fine.

So hopefully one of you guys have heard of something similar, I quickly scanned the site but didn't see anything, probably just too strange.
Thanks for the help in advance, Dave

Everything you mention is controlled by circuits passing through the IPBEC (fuse box behind glove box). Would be a good place to check for any corroded/dirty connectors. If connector cleaning doesn't resolve the problem(s), the BCM could be at fault. Someone proficient with a diagnostic scantool may be able to determine if that's the case.

I was afraid of that, use to be I could contort into most any position but today, being 62 and the back surgeries I've had those days are gone. Is it an easy way or semi easy way to unscrew that fuse panel to drop it down? The way I chkd the fuses was a cell phone photo, not the best but it worked.
Thanks guys, Speleos I can always count on a reply with good info. Once I get it done, probably weekend, I'll post something back with the outcome. Got a friend that owns a shop that can scan it so might go that route too. ;)

It's a PITA getting to the fuse box. Hope you have plenty of Aleve!

I figured as much, might get my son to do it. Also talked to my shop and he said they'd diag it without it costing me an arm and a leg. I've known this guy for years, a friend that's helped me out when stuff gets beyond my ability. Still I hate doing it this way, one of those things when you had the ability at one time and now you don't.
Aleve ain't going to cut this, just getting in the position isn't possibly, got too many rods, pins, and plates in my back/neck. Years of doing hard, heavy work, auto wrecks, dirt bike, you name it. Surgeon asked me once if I had to do it over would I do it differently, I said sure, would do it even harder.
Nah, I'm not sorry for what I've done in life, been a sweet ride just not easy today. My faith also helps me everyday, good wife and kids. It's only as big a deal as you want to make it an I don't do big deals anymore.
Thanks for the help, I don't think it's serious but just what you said it is, makes sense.

I empathize with you, except it's PA (psoriatic arthritis) that got a hold of me. Plus, meds made my skin so thin that all it takes is a little bump and I'm bleeding all over everything.

Regarding diagnostics, I have been very pleased with my ThinkDiag code reader. It's not perfect, but will scan all of the modules in my Acadia, as well as do some bi-directional commands (such as activate locks, windows, etc) to help with diagnostics. The unit itself is about $120, and that includes the full package for one or two brands of cars.

I purchased a two-year subscription for the whole shebang and have found it to be extremely helpful when either helping family members with their cars, or looking at cars to buy. I am sure there are similar products out there that make sense for owners of cars that are getting on in age, but this is the one I stumbled upon. For the price of one visit to a shop to run their diagnostics, I would say this puppy is more than worth the cost. THINKDIAG Blue Tooth Dongle

Just curious. . . are there different "levels" of subscription services or just 1 year, 2 year etc? The "subscription" prices don't seem to be evident on the website. How much is a 2 year for instance?

Pretty sure they ran a special for 199 for a two year all inclusive, less thirty buck if you have purchased at least one of the specialty functions (immobilizer, ABS Brake Bleed. TPMS, etc), or another brand of car. The fleet of vehicles I take care of includes my Acadia, three Saturns, a Cadillac, a Ford Ranger and a Chrysler Town and Country. Add to that neighbor's vehicles that happen my way, and the occasional trip to check out a used vehicle and, well, it just made sense to go all in. The device is not perfect. There are some things it should be able to do that it can't, but overall, it was a great investment.

A few weeks back I replaced the steering wheel position sensor on my stepdaughter's Saturn Aura, then last week I replaced the brake position sensor on my stepson's Cadillac CTS. Both those required calibrations that the ThinkDiag handled easily. Don't know what it would have cost at a shop, but probably 75 each plus time and effort to get it there.

Last week the Accelerator Pedal Position Sensor (gas pedal) went out on my Acadia. I was able to pull up the code and see the voltage data from the two sensors in the APPS within minutes. Fifty five bucks later for the part (and a few days for delivery), and the problem was solved.

I would not attempt to DIY repair any modern vehicle without this or a similar device.

Looks like they do a better job of explaining the options under the thinkdiag mini page. Not sure what the functionality difference is between the two, but the larger size has bidirectional controls which the mini may or may not do. The big package was offered about 6 months ago, so they may have been looking for money to help launch their new line of standalone products under the platinum line.

In a couple of years, someone else will probably offer the same functionality for a lower price. In the mean time, I am going to the shop for code reading as little as possible.

Bingo! There are too many stories here and other places about people throwing parts at a vehicle without knowing what is really malfunctioning.

Talking with the guy that runs the shop I use we figured the problem but he put one of his best mechanics on it, an electrical specialist. Seems the power seat, seat heater, back up detector, and garage door opener are all on the same circuit. Power seat grabbed the cable that runs beside it and cut the wire. Mechanic said it probably took some time to do since it had to cut through the casing and tape. He had to take the seat out to repair it.
Cost for parts, 2 fuses, nothing, labor $200 and he re-routed the cable so the seat won't grab it again. Would of cost me much more if I had of forced my way under the dash, I'd be typing this from the hospital tonight!

Thanks for the follow-up. Glad someone could fix it for you. (y)
