I recently purchased a Jayco 12v fan/light combo (https://www.campsmart.net.au/jayco-camper-expanda-bed-end-light-fan-combo). When plugged into one of the 12v plugs (in the light unit) of my Jayco Flamingo the fan spins the wrong way (the light works). Any suggestions?

Swap + and - somewhere because it is wrong.
Find out where first....

A lot of 12v appliances use American colour coding, White = Neg and Black = Pos so it's easy to get the wiring wrong.
As Peter has said just try swapping the wires.

thanks, i'll give that a go. Interesting that I bought two, and one spins the right way, but one doesn't!

It is more likely to be the van wrong than the fans...............
Test with a multimeter.
Cheers,

just checked. both fans work properly at one light, but neither spins the right way when connected to the other light. So definitely van wiring. Not sure that will be an easy fix for me!

Can the blade be reversed ?

That would be like tipping an aeroplane wing up side down...... it won't work very well....

It should be relatively easy to change over the van wiring at the light
From the sellers site"Polarity Issue:
In about 5% of cases customers report the air blowing in the incorrect direction from the fan. In all of these cases, it has been found that the fan once returned and tested was working fine. The issue the RV has been wired the wrong way around. This issue doesn't effect lighting and so people will generally be unaware of it before purchasing the fan.
Please note that we are not responsible for this & in purchasing the buyer accepts that any returns for this issue are at the buyers cost and must be in line with our returns policy.

Are the lights LED? If they are, they will not work when the polarity is reversed. If this is the case, then you have to look at reversing the fan blades on the shaft. Knowing the quality control on most vans, I suspect that the wiring is wrong.

And that does not mean taking the fan off and installing it back to front........

Just for information sake.... Most LED's these days have a builtin Bridge Rectifier, therefore can be wired either way. Additionally, newer generation LED's are also Multi Volt as well which allow for input voltage from 10v to 30v DC and the output voltage is set around 11v DC making them more efficient that the older LED's that were strictly 12v DC.

You obviously missed the bit in bold.... perhaps I should have put that bit in 300 point type.

Much better to do the sensible thing & correct the van wiring @ that point, that is wired incorrectly ,so that it is wired correctly for polarity, I do hope they managed to wire the van 12V light switch ,if fitted , correctly in the POS line
To the OP , edit just reread your OP
Very obviously one jack has been wired wrong way round
,If you are concerned about doing any damage in trying to rewire it ,I suggest you take the van to were you bought it & DEMAND they wire it correctly

Command Electronics,
"this reading light & 2 spead fan plugs into the 1/4" (6.4mm) 12V jack in the nearby light unit on Jayco Camper Trailers and Expandas.""
ONE jack is wired incorrectly ,or if you have some form of double adapter one of those outlets is wired incorrectly
The fans etc are mass produced, very very unlikely that one would be wired the wrong way round
The actual connections at both the fan motor & the plug would no doubt be welded or soldered connections
I strongly suggest you leave them alone.
DO IT ONCE & DO IT RIGHT

Hi KJB
Yes that is correct .
Most modern fans blades are directional

You can reverse the fan blades on the spindle all you like but they will still blow the air the same way, so this will not help. Only changing the polarity and spinning the blades in the opposite direction will change the air flow direction.

And most likely at reduced force/volume at the front

DITTO to that
Check the polarity @ the plug
FIX the fault
Not a bodgy cure
You never know when you may wish to run something else that is polarity sensitive from that plug

It sounds like you were sold a model intended for use in the northern hemisphere. Reposition the fan by turning it around by precisely 180 degrees so that now you are sitting behind it - then you should be cool
