PostSubject: A/C fan question   Thu Jul 18, 2013 10:47 am

I am trying to figure out if the axillary fan is supposed to come on when the A/C is on. My mechanic buddy tells me that it should but I dont believe so. He had the A/C gauges hook up and jumped the fan to come on. The upper pressures dropped when the second fan came on.

So my question is: Does anyone have both fans come on when the A/C is on Max? Or do I just get the smaller primary fan?

I know the second fan is set to come on when the engine temp gets to a certain point.

Thanks!

Ok, I just checked for you.

My AC on max, engine running, BOTH fans are on.

The problem is that on the National forum they are saying that the second fan is only supposed to come on when the upper pressure in the A/C system hits a certain point.

The factory manual is hard to understand when it comes to the second fan, but it seems to confirm that the second fan should not come on until a certain point.

With a cold motor just started and the A/C switched to Max the system should not be built yet to high pressure yet. So that would indicate that the second fan would not be on.

So what I would need to know if the second fan is on with the engine just started.

Ok, what I've got is a semi warned up engine.

I just started it with AC on max.

Both fans on.

I turned AC off and the drivers side fan slowed to a stop.

FWI there's no "smaller fan". They're the same size and because of that, one is canted lower.

I have a very original 95 Impala SS. The fans are different sizes. V03 option code. The primary fan on the passenger side is smaller. This is correct.

Strange... I have VO3 too.

Not sure what very original has to do with it. I rarely see anyone install aftermarket fans if that's what you mean.

According to my factory manuals the fans are two different sizes on the V03.

I see yours is a Caprice police. They may have had different fans.

My FSM says your FSM is full of shit.

The only difference is motors. VO3 cars had a 150w and 240w respectively for the 2 fans.

Base models were 150w and 100w.

VO8 is 1 electric fan, one mechanical.

I think you're confused by the fan on the passenger side mounted lower in front of the AC pump.
Looks smaller.

Perhaps I did not use the correct terminology. What I was referring to was the motors size, no the physical size.

Aha! There it is.

In that case, then you are correct, just as the FSM states the differences for the various RPO codes.
