You're selfsame receive, Bryan/Bryna.

Because, as I aforesaid, it is used for *all* years with the 2.7 engine (accordant to the FSM schematics). I testament admit that it's puzzling that the same two rooter assemlbies are mentioned in all twelvemonth parts pdf's. I assume one is what I have referred to as the "ulterior design". The schematics for the in the first place geezerhood only show one version. I don't do it if there are any or many examples of the other one in true cars of pre-'01 in the wild (as same, '01 was a transition yr and a mixed cup of tea).

If I recollect correctly the passenger side devotee is the A/C fan and that it should change by reversal whenever the A/C system is on.

I've read this in years past too but in recent events believe this to be improper. From what I've read, all MYs, both fans run at the same time. IT's only whether or not they are functioning flat-growing or high. Merely at a given point after touchdown turning the AC on, would the fans operate at high speed. I don't believe this to be immediate??

Well this is something I didn't get into in this train of thought up to this manoeuver because it wasn't pertinent to Boy Orator of the Platte's job, and the subject is already confusing.

Having said that, below is from a post I did last year along the content - fanny line is that the later design has the *capability* (if the PCM is rhenium-programmed to rent advantage of it) to have just the passenger lateral fan turned on high speed with the number one wood's position incomparable off, which is not possible with the earlier invention (because in the before design, the windings of the two motors are connected (hard-wired) in parallel and there's *no* way to operate them independently of to each one other). I do not know for sure if the PCM is programmed in the vehicles with the later intention to utilize that capability or not - I' ve never gotten a conformable answer from people on the forums with the later year cars to come to any distinct conclusion about that - maybe some of you can do that now. The question is, connected '02 and later (Oregon 01's with the two relays happening the fan assemblage), with the fans operating right, if the rider side fan sometimes comes on peaky speed by itself, or are the fans *always* operating in tandem bicycle? It may very wellspring be that they do operate the rider side winnow separately sometimes when the a.c. is on. I nigh have to believe that was the motivation for the design modification to begin with, otherwise, why did they love (at the expense of two more relays)? (It is latent that information technology was only to reduce the cost of the motors by going from 2 windings all to only one.)

Anyway, Hera are Thomas More details of that from my previous post (http://300mclub.org/forums/viewtopic.ph ... 08#p257608):

Here's what I bed:

The '98-'01 FSM schematics bear witness a different cooling system devotee motor internal wiring and control setup than the schematics in later year FSM's. The earlier year cooling fan plan as shown in the FSM's *only* allow some fans to operate in exact in tandem - i.e., at any precondition minute, both fans are either off, lo, or hi.

(FWIW, for truth and completeness, the after year ICSH car schematics show that cars with the 2.7 engine actually retain the fan motors and controls wiring of the to begin with years - the new design As I descibed is used only in the later-twelvemonth 3.2/3.5-engined cars.)

Unlike the earlier years design, the later years design would allow independent control of the two fans equally far as the motors, relay race, and wiring according to which of the two relays, low speed and high speed, are energized past the PCM as follows:
- Both non-energized: Some fans away.
- Low gear pelt along relay sole energized: Some fans along low speed.
- High Rush electrical relay only energized: Fan No. 1 on high speed, Fan No. 2 off.
- Both relay race energized: Both fans on high speed.

The FSM (1) goes out of its way to comprise *very* ambiguous in its description of fan operation as far as both fans in reality being on at the same race at the Lapp time or non, and (2) goes out of its way to non identify which fan motorial is no. 1 and which is no. 2. I besides highly suspect that a couple of statements in the FSM on the cooling fan operation are downright incorrect. IOW, piece I trust the schematics, I wouldn't base any conclusions on exactly how the cooling fans operate on what the FSM says in its descriptions - I think the writers hedged it because they themselves didn't understand it.

If they do use the mode with Buff No. 1 on high speed and Fan No. 2 off, they would equiprobable wont that mode to turn on the winnow before of the a.c. condensor on when the a.c. is running, which would make Fan No. 1 the one on the passenger side - also that would be the same conventionalism As the enumeration of locomotive engine cylinders and the O2 sensors, with number 1 of whatever start is beingness talked approximately existence on the passenger side - but that is speculation on my part.

NOW - whether they use that 1-fan-on-hullo-and-the-early-fan-off mode in the subsequent years is strictly dependent on if they wrote the microcode to use it or not.
