Piston Slap: Why You So Stupid, Smart Junction Box?!

TTAC commentator claytori writes:

Hello Sajeev,

This email is about my 80-year-old mother-in-law Shirley, who is a sweetie and thinks I can fix anything. I hit the MIL jackpot.

Shirley owns a 2010 Lincoln MKZ 3.5 V6 with about 35,000 miles on it. About a year ago, the battery died on the Lincoln. CAA replaced it with another battery with a 13-month replacement warranty, on which less than 1 week remains.

Two weeks ago, the car wouldn’t start again, so I boosted it from my Saab 9-3, which sits beside the Lincoln in a heated garage. It started right away. As she doesn’t drive it more than about 3 miles at a time, I drove the car for a day to charge up the battery.

The battery was great for two days — then dead again.

Piston Slap: TIPM and the Freemont's Enlightening Journey Down Under

Just a city boy, born and raised in South Detroit (photo courtesy: blog.fiat.com.au)

Thanks to the 40+ people who sent queries to Piston Slap over the week. I’ve insisted the satisfaction derived from our interaction is why I keep writing, that everything else is merely gravy. Delicious gravy, but just that. You’ve once again validated that fact. – SM

Good Morning Sajeev,

I am asking a question about the headlights of my 2015 Fiat Freemont, 2.4-liter 4-cylinder variety. In particular, replacing the globe in the left headlamp assembly. In the manual it states to move/relocate the TIPM. On the forums there is nothing mentioned about how to remove this particular item, plus I read all the horror stories about the TIPM, unreliability, etc.

Piston Slap: The Body Control Module Electric?

Good Afternoon,

Today when I got into my 2002 Saturn SL2, the power door locks started chattering. Each door, over the space of about 45 minutes, had the same thing happen. Sometimes it would be one at a time, other times it would be two or more. I also noticed that the inside locks – the “up/down” button, not the little lever you use to manually unlock the car – would not work, only later to work. For now I have removed the lock fuse and that stopped the problem. I wait and plug the fuse back in, and the sporadic chattering once again begins. Sometimes it is completely quiet. Any thoughts?

Thank you!

Hi Sajeev,

It’s me again, steady reader, random poster/questioner, with another D21 question. My good old ’94 Nissan D21 is soldiering on, 213,000 and steady on. Of course I don’t ever thrash it which I’m sure makes a difference.

But to get to the point: the other day I went out to go to work and presto! No low beams. High beams, check. All signals, markers and brake lights, check. Just no low beams.

Piston Slap: Spastic Saturn's Spacey Door Locks?

TTAC’s own Ronnie Schreiber writes:

My mom’s ’02 Saturn’s SL1 power locks freak out sometimes, sounds like solenoids are having spasms. I’ll go to lock or unlock them and they’ll start fluttering. Sometimes slamming a door will stop it.

My guess is that there’s a dirty switch somewhere, might be weather related too because it started happening in late autumn. It was easier to diagnose things when they didn’t use logic circuits for everything.

Piston Slap: The Cadillac Hack

Geek alert! This one is tech-heavy!

Sajeev,

Not a question, but it’s good to know that as long as there are cars there are people who will come up with hacks, no matter how complicated things get.

I have an 1992 Cadillac Seville and the blower motor fan disintegrated and jammed up the blower motor, which in turn shorted out the blower resistor. The squirrel cage disintegrated. I checked inside the blower housing to see if there was anything loose, but I could find nothing except pieces of the fan. All of this stuff was OE, no one has been in there since the car came from the factory. I’m sure someone at GM thought that saving a nickel on plastic was a good idea. Well, I bought a new motor/fan assembly and installed it. Wasn’t too bad, about $40. When I tried it, it was a no-go. Next thing I do is check the fuse (30 amp) it was fine. Then I checked the blower motor controller. It was blown. Crap! Apparently when the fan blew up, it jammed the motor, which then took out the motor controller. I’m thinking to myself:

“Nice engineering. The components on this circuit blow before the fuse does. WTF is the fuse for?”

  • Ravenuer 15 Overpriced Vehicles? I'd say they all are.
  • Ravenuer Bought a new 96 GXE. Paid $25002 for it. Hands down the best, most reliable car I ever owned! Put 300k on it with only minor repairs. Miss it.
  • Bfisch81 My friend's mom bought a fully loaded 96 and I remember really liking it. I still thought my granddad's 89 was cooler and sportier but the 96 felt more luxury which wasn't a bad thing in and of itself.
  • Art Vandelay Battery issues aside, I didn’t hate it. I’d have just been paying for range I didn’t need.
  • THX1136 Saying that because 'marked up' vehicles are selling means they are not over priced assumes the folks paying over MSRP know that they are paying more than the manufacturer price set for the vehicle and are happy to do so. I'm guessing in some instances it may be the buyer is ignorant of the situation - or buys with a 'I gotta have it now, I can't wait' attitude. As others have mentioned if one does the work to find a fair price, they don't have to pay an inflated price. Laziness enters into the equation too. But I would agree, generally, that if folks are paying an unreasonably high price they must be okay with that. If demand drops significantly, prices would moderate. Big if.
