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.
Slamming the door will stop it?
Perhaps the sales pitch where a Saturn salesperson hits the door with a baseball bat wasn’t such a bright idea after all?
After some googling on the Saturn forums, this is a common problem. That said, this shockingly thorough post covers my two possible faults: a bad relay or a busted switch. Considering the door slam fix, the switch is bad.
Much like a well-worn record, the internal (copper) connections in switches can wear out over time. Or the springy action of the button can disappear, making it activate when least expected. Considering the quality of GM interiors from this era, a worn out switch is also more likely than a bad relay.
So I’d disconnect the driver’s side power lock switch and see if the problem comes back. If it does, attack the relays in the link above. If not, there are plenty of new door lock switches on eBay for dirt cheap. I saw a brand new switch for $22…$27 shipped. Nice.
Done and done: off to you, Best and Brightest.

Well, if slamming the door fixes the problem (temporarily), why bother spending money until the switch is absolutely, positively broken? Just keep slamming until the switch has to be replaced, and keep your money in your insured savings account earning 0.004% interest.

- DenverMike When was it ever a mystery? The Fairmont maybe, but only the 4-door "Futura" trim, that was distinctively upscale. The Citation and Volare didn't have competing trims, nor was there a base stripper Maxima at the time, if ever, crank windows, vinyl seats, 2-doors, etc. So it wasn't a "massacre", not even in spirit, just different market segments. It could be that the Maxima was intended to compete with those, but everything coming from Japan at the time had to take it up a notch, if not two.Thanks to the Japanese "voluntary" trade restriction, everything had extra options, if not hard loaded. The restriction limited how many vehicles were shipped, not what they retailed at. So Japanese automakers naturally raised the "price" (or stakes) without raising MSRP. What the dealers charged (gouged) was a different story.Realistically, the Maxima was going up against entry luxury sedans (except Cimarron lol), especially Euro/German, same as the Cressida. It definitely worked in Japanese automaker's favor, not to mention inspiring Lexus, Acura and Infiniti.
- Ronnie Schreiber Hydrocarbon based fuels have become unreliable? More expensive at the moment but I haven't seen any lines gathering around gas stations lately, have you? I'm old enough to remember actual gasoline shortages in 1973 and 1979 (of course, since then there have been many recoverable oil deposits discovered around the world plus the introduction of fracking). Consumers Power is still supplying me with natural gas. I recently went camping and had no problem buying propane.Texas had grid problems last winter because they replaced fossil fueled power plants with wind and solar, which didn't work in the cold weather. That's the definition of unreliable.I'm an "all of the above" guy when it comes to energy: fossil fuels, hydro, wind (where it makes sense), nuclear (including funding for fusion research), and possibly solar.Environmental activists, it seems to me, have no interest in energy diversity. Based on what's happened in Sri Lanka and the push against agriculture in Europe and Canada, I think it's safe to say that some folks want most of us to live like medieval peasants to save the planet for their own private jets.

- MaintenanceCosts There's no mystery anymore about how the Japanese took over the prestige spot in the US mass market (especially on the west coast) when you realize that this thing was up against the likes of the Fairmont, Citation, and Volaré. A massacre.
