Neon AC compressor cycling

Well, someone is mud wrestling with a pig....

You were absolutely certain about the OEMs recommending that you run you AC in the winter, or were you?

Oh, now it's just one car. Quite different from your earlier assertions, no?

Why is leaving the van sit for two weeks the same as not running the AC in the winter?

Hell, I unplug my AC compressor clutch during winter, have been for eight years on my Dakota and it still blows as cold as when it was new without any service what-so-ever.

So what should happen when someone is absolutely certain before they even check their owners manual, then -does- check their owners manual and finds out (ta -da) that they're wrong on all counts?

We could use Red Forman's favorite term....

As for arguing points you claim you never made, let's see...

You claimed that the OEM recommends running your AC in the winter to keep things lubed. Yup, I argued that to be the horse doody that you now know (with but one exception) that it is.

You (or one of your gaggle) claimed that AC is needed in winter to dehumidify the interior air. Yup, I argued that at some temperature the AC isn't going to run anyway because the system pressures would have dropped to low to allow clutch engagement and by the way, it really isn't necessary because usually at that temperature, the ambient (intake) air is ALREADY quite dry to begin with. Naturally, you thought you'd argue your way out of all that by claiming that not all parts of the continent get that cold so there, nyah-nyah-nyah, you're dead wrong Neil.

You guys crack me up.

Really, this is great comedy, where's the hat?

Hey genius, did you bother to check that Green Bay (and Milwaukee) is in very close proximity to a very large body of water and that that very large body of water acts as a heat sink during the summer and that it -is- a known fact that both cities benefit from moderated temperatures during the winter because of that.

Here, let me make it real simple... You picked a really BAD example.

On the other hand, if you pick the two correct days in 1995, Green Bay had both the lowest temperature in the nation and the highest temperature in the nation (ya know, that schtick they do on the 10 o'clock weather).

So you see, it -can- be colder here in winter than parts of Alaska and it -can- be hotter here than the desert southwest.

Ain't weather fun?

So what did sink the Edmund Fitzgerald?

Why?

Why, what's different?

My calendar doesn't go up to "once in a while," just how long is that exactly? Why is it then that the compressor in my dakota has not experienced any sort of failure and still blows as cold as when new in spite of the fact that every winter (oct-june) I disconnect the plug going to the compressor clutch, but the compressor on the Intrepid seized during the first winter after I bought it used but hasn't in the subsequent winters now that I unplug the damn thing? Seems that I'm doing everything wrong but yet I'm experiencing fewer failures that what is the norm based upon complaints in this newsgroup.

Gee, I dunno... seems that I routinely test drive vehicles in the winter, bring 'em in, rack em and have absolutely no problem grabbing the exhaust or cat-con with bare hands shortly after shut down. So, you're claiming that the AC system is going to absorb heat from the engine while the car is running down the road with wind blowing in and thru the engine compartment, 'eh?

Last time I checked, August 21st does not happen in winter in this hemisphere. Thanks for playing, you've won an authentic Wicked Weasel bikini (which I'm sure you'll look great in).

Probably an ultralite....

Because the a/c SYSTEMS ON LATER VINTAGE VEHICLES ARE "automatic"

Lots- controls to start with. AC and heat are integrated. Some of us are old enough to remember when that was not the case.

Here in Ontario, with my New Yorker, at least once a week through the coldest part of the winter. With my Pontiac Transport at least as often

Even a blind pig finds an occaisional acorn - in other words? DUMB LUCK.

Yup - blind luck.

Might not come on while blasting down the road at 60MPH, but how about when you stop the car at a stop light for a few minutes, or driving slowly in traffic?

OK, now you're changing the question and the rules. Nobody specified WHEN the Neon had to become "airborn" and the auto road is open all summer, most of the spring, and fall.

Nope.

Really?

Why is it that none of the schematics shown even remotely resemble an ignition primary?

Here, 'splain it to me.

V- -------I R2 I I______?? I I R1 V+ -------I

R1 = the ballast resistor. R2 = the ignition coil primary windings. Crude rendition based upon all of the wonderful examples that were so generously collected by the brain trust that I lovingly refer to as "the gaggle."

Okay Clare, the item marked "??" is which component in the ignition primary?

Actually, they have. pity you haven't been paying attention.

No shit Sherlock.

Do tell, when did AC system seals become of the type that they'd soak up refrigeration oil? How does a two piece carbon seal soak up refrigerant oil?

If all of these seals are soaking up refrigerant oil to stay supple, why isn't there a big puddle of oil dripping off of them?

AC seals don't come packed in oil like Sardines, and I have yet to see a best if used by date on any of the hundreds that I've handled, they're not vacuum packed, so how do they keep them supple while they're awaiting their new home sitting on the shelf in the parts department?

Clare, you're posting ridiculous stuff now....

I mean holy shit, I make one comment on some ill founded myth and instead of dispelling that one, you come along and add more to it. Are any of you playing with a full deck?

Well, there are things that won't happen, and there are things that don't need to happen. That summarizes exactly what I've been saying in about as plain of english as one could want.

Hell, if it makes him feel good, then he should do it. Seems kind of like that Monk character on TV though.

I guess that would include not believing that it's winter in New Hampshire in August, 'eh?

That's nice information and all, but someone interjected aircraft into this discussion so I'm afraid all of your above cites are disqualified because they appear to be land based non flying attempts.

No prize this time. :-(

I was speaking about automobiles on the ground. We both know that altitude changes everything.

Can't help ya there, both vehicles pre-date my career. Around here, back when most everything had carburetors, icing would only occur when the temperatures were in the low to mid 40s with the humidity exactly right. (don't recall what the RH was)

I'd bet that there was water contamination in the gasoline, or whatever they claim to be gasoline in Africa.

I do remember there being a very well written article in Sport Pilot back in the early 80s on carb icing and it pretty much stated what I've experienced with automobiles.

The taps *are* the junction between coil primary and ballast ("top") resistor. Just because you haven't physically brought out that junction and call it a tap doesn't mean that that dropped voltage node doesn't exist (sorry for the double negative - sometimes they are appropriate). Fact is that that node exists and represents the reduced-voltage input to the coil due to current induced voltage drop - once again, precisely how a voltage divider works. You're beating a very dead horse here, Neil.

Bill Putney (to reply by e-mail, replace the last letter of the alphabet in my address with "x")

See my other post (answer: the "tap" is the junction between the ballast resistor and the coil). Tapped just means a junction is brought out to register the voltage at the junction (voltage node), or can be applied to the load (which in this case is also the coil). Just because you can't bring a wire out for that purpose doesn't mean the junction isn't there - it is there.

Uhh - a condensor (capacitor to Americans) is not shorted - it is open (d.c.-wise).

Please inform the climate control engineers at several automakers of your beliefs/assertions. The obviously know less than you do.

Dan

I think it was Gordon Lightfoot's fault.

PKB

Indeed.

That's because Clare is either lying or she's such a shitty tech that she can't even properly discern carburetor icing from other operational difficulties.

Both of the vehicles she mentions -- for the Canadian market only in '63, but for the US *and* Canada in '69 -- were equipped with a very effective carburetor anti-ice system. It worked almost exactly like the heat-tube style automatic chokes used by automakers other than Chrysler: A pipe carried air from the clean side of the air filter through a sleeve passing through one of the exhaust manifold runners (Number two runner, in fact). The asbestos-insulated pipe exited at the top of runner 2 and ran from there to a 3/16" IV-flare fitting in the throttle body. The internal channels on the other side of this fitting were angled such that a steady stream of heated air was distributed across the throttle plate and immediate vicinity. Vehicles equipped with this anti-ice system basically

My Canadian-market '65 Valiant w/225 had this system. If in summer I forgot to bypass the heat sleeve and run directly from the air cleaner fitting to the throttle body fitting, the carb would reliably percolate upon shutdown or extended hot idle. If in winter I forgot to put it back, and the temperature was around 38 to 48 F, the carb would reliably ice about 8 or 9 minutes after initial startup from cold. Colder or warmer ambient and it wouldn't happen. This was at 5500 ft elevation.

Gee, the ones in my Intrepid and Dakota aren't Automatic although it (automatic) was an option in the Intrepid.

The fact that there were units available that hung under the dash hardly supports you case.

You should get it fixed.

Find someone to fix that one also.

That's a very scientific explanation Clare. maybe a little dumb luck will come your way and you'll be able to spell occasional correctly on an occasion.

Careful, too much science might be bad for you.

"Might not?" So, actually, you're not sure of a damn thing, you just post what your emotions tell you without any regard for actual fact.

I didn't mention that anyone had given birth to an automobile either, but here you are adding -that- into the discussion.

Then it must be radio controlled or control line...

Seems to me that you just choose to use words without any thought towards their context.

Yes, I know that... On the other hand, when was the last time you bought tune up parts and one certain component was labeled capacitor? re: what I wrote above about context.

Seems pretty simple to me, all you're interested in is to generate spin Bill.
