Heater Fan Problem - 2013 Ducato 130 base vehicle

[Falcon 269]

Hi,

The heater fan in our 2014 Adria (2013 model base vehicle - curvy headlights) has started playing up. Intermittent loss of speed settings 1 - 3 inclusive but setting 4 continues to work fine.

Search here suggests resistor pack failure but the intermittent nature of the fault makes me wonder whether it might be related to the control switch instead.

Does anyone have any experience of this fault and if so, what was the fix, please?

Also, any information on how to remove the fan control switch would be much appreciated. Have looked on Google but can't find anything much that is of help.

Thanks in anticipation.

This is a notorious problem. I can only relate my own experiences.

1. Yes, the first time it was a resistor pack that had failed.
2. One failure after another, local garage fitted two resistor packs within three months. Investigating myself
I discovered that manipulating the wiring brought the heater into life. Removed the connector and found one cable burnt almost through. Solution was a new connector with cable ends attached. Plenty of these on ebay but beware that there are different combinations of pins used and cable thicknesses to each pin. Identifying the correct connector is a nightmare.
3 The latest failure, again manipulating the wiring brought the motor back into operation but this time it was simply poor pin contact. Tightening just one of the pins cured the problem.

Diagnosis is the key.

when my 2007 van would only work on full speed i found the plug not located properly, think it had probably been hit by a passengers foot

Many thanks to you all for your replies all of which were very helpful.

I should perhaps have added that ours is a left-hand drive in case it makes a difference to the location of the resistor pack but it's got to be somewhere between the left and right hand doors, so I should be able to find it.

I'll report back in due course but any other advice would still be appreciated.

Cheers!

i have the same problem. will have another look.

OK, update after a bit of troubleshooting today.

First, on a left-hooker, the fan unit and resistor pack do live under the passenger side below the glove compartment. Why do we still call it a glove box, BTW ... when was the last time anyone wore gloves for driving? I digress.

The retaining screw is a 5.5 mm hex head, a size that doesn't feature in any of the many bit sets in my workshop. Cue much upside down phaffing with pliers to get the sod out. Second challenge was seeing how to unclip and slide out the resistor pack - not easy when looking upwards at short range with varifocals. I digress again.

No signs of any overheating of the wiring or contacts but I did notice that the connector was slightly out of place. Pressed it back firmly, refitted the pack (using a cross head screw) and tried the switch. All good. Hurrah! For now.

I'm guessing that the Soup Dragon's size 6 left hoof may have nudged the connector or wiring loom at some time on our jaunt over to Germany this past couple of weeks. She has received a yellow card as a precautionary warning.

Fingers crossed that this is the problem resolved until such time as the resistor pack genuinely does give up the ghost. Fingers also crossed that Soup Dragon doesn't read this post.

Thanks again, folks. That's all!

Hi

Hi cranky, just wondered if you'd fixed your fan problem. I have a 9010df 2010 and had the resistor replaced last year. Took the MH for its post winter shakedown a few weeks ago and fan not working properly again. Auto sparks diagnosed failed fan switch but dealer could only supply a full control unit £300+. Had it fitted, all working now £1000+. Plastic casing at the back of the switch was badly melted so didn't need to see any more. The individual switches are available and I have bought one and fitted it to control unit they removed so fully functioning again (Manufacturer Part Number: 1614183080) £25 off Ebay for the switch. Hope this helps.

I've had the connector go toasty twice. I think fidgety feet kicks the connector lose and the increase in resistance heats it up. It's not a great design.

Thanks. I'll keep an eye on the connector now I know where it is.

A pothole on the A12 sorted it out!! couldn't avoid it and gritted my teeth but a couple of minutes later realised the fan was working on all speeds. Thankfully no damage to wheel or tyre!

Shall go through the potholes in the doblo when next I go down to the storage see if that works, my resistor is in a spot it would be fairly difficult to kich/dislodge but with the roads we have could easily have vibrated free. Will have a play when i have more time

when you replace the resistor pack many will also supply an uprated wiring harness at extra cost to prevent a repeat.

when it does it intermittently another method is to put resistor in a plastic bag & in the freezer overnight. resets it . worked a treat on my last van

Re-seating the under bonnet relay on mine got it working again
