Dashboard removal and constant running fan
« on: June 24, 2021, 10:33:52 PM »
Hi from Somerset,

had a look through posts but without search, difficult.   Anyway, Had a spare MK (2006) Diesel in store for a few years and now trying to get going (other two rusting away!).

All the time the ignition is on, there is a very quiet fan of motor running behind the dash, top centre - possibly on the heat exchanger unit.  Starts up slowly and quite quiet.  Not there on another version of same model.    Run VCDS and no errors relevent to the heater etc.  Pull fuse 3 (air con etc etc ) and fan stops.

Firstly any clues?  Very quiet and slow running.  Pulled out radio etc and can hear louder!  Might not be important but worried something is back feeding a fan.  Definitely NOT the main aircon/blower fan as noise from a different place.

For cleaning and finding this and some extra wiring, trying to remove the lower dash and can not find the full instructions.    Centre console out. Drivers panel and trim out. Passenger side top trim out, all fixing bolts out, two bolts below glove box and two above out.   Large nut behind centre console that holds bottom out. Bolt behind radio out.    Still won't budge and seems something holding at top.   Looking carefully at top fixing rail see two places that look strees points as if some kind of fixing behind - and yclues as do not wish to break!!

Finally is there an EASY way to remove the lower glovebox lid other than prise the two pins out of the hinge and risk breaking them off?


Cheers
John

Do you have climate control as that has a small fan for the internal temp sensor? Try unplugging the climate controller if you do and see if noise stops

Dashboard wise it’s been a long time since I had mine out but I do remember there are some nuts engine side on the bulkhead that need removing,I had my cylinder head off at the time so access was easy but I suspect with engine in tact they could be a bit tricky.

Are you sure its not the run-on pump? Is it a 115 bhp? They come on with the ignition on those and run on for around 3 minutes after turned off.

There is a single bolt that you need to remove from the centre of the bulkhead, engine side. Its between the pollen filter and wiper linkage motor.

The bolt described above is located next to the arrow on this photo.

Its possible to remove it once you know where it actually is, but you can't see it. If you feel behind the pollen filter area with the scuttle out, you should find it.

Many thanks all.

It was lower dashboard and couldn't find the "hidden" screws behind cup holders - nor the slots to get them out - mine was different from all the pictures but sorted now thanks.

As for the fan, yes, it was fan inside aircon head.   Took apart, cleaned etc as blocked solid, but runs as soon as engine is switched on, even if aircon head is switched off.....On my second car, same model, same head, the fan does NOT run when just engine on - hence the query here.

Had both units apart (as second one clogged up as well) and find they have different fan assemblies and pcb.   One that runs has a 2 wire connector whilst the one that doesn't run has four.    I can repair circuits without drawings (my business) but not sure yet if drive transistor failed or this version is meant to do this!    Any thoughts out there?

Now to try and un-seize the corroded wiper bushes......never ends!

John,

Can’t say I noticed my galaxy one running all the time but I also doubt I ever had hvac controls switched off.
I know my current bmw the internal temp sensor fan runs the whole time ignition is on regardless of hvac settings. So I would hazard a guess and say the one you have running all the time is probably meant to.

Know what you mean about never ending jobs I always seem to have cars like that,good job I am partial to tinkering in the garage. On plus side the wiper spindles aren’t a particularly bad job to sort out as I remember doing mine.

If you have the old type aux heater let me know as I have a spare working glow plug in the tool box (somewhere) you can have,just send me address and I will stick it in the post.

Hi Johnny from JR in Watchet
Nice to catch up again!

Nightmare here with 3 x Galaxy.   My petrol one bought new in 2001 still runs fine after 200k miles, but sadly being on the coast, started to rust away - both cills very badly vanished where been jacked in past on wrong points and not worth 800+ to replace them as heaven knows what else will be found - it was a 5mm hole 'til I poked a little to check and ended up 20cm x 8cm up under front wing one side!

Second diesel we have chatted about before when I located a new aux heater - that works fine but odd rattle at tickover and guessing the dual mass flywheel - no time to do it as driving to Czech this coming weekend.

So time to use a "spare" 2006 diesel I bought a few years ago and put in dry storage.    That's the one with the odd air con head.   No probs at moment as sure my local mate who runs a breakers will have another one in sometime soon for me to rip apart - quite useful that - he has already had a pool table for boxes of spares and now wants a video game, so plenty of "credit" there!

New car was filthy, so stripped everything out.  Dash is out to find fan noise (well was half way out) so now wiring in mirror camera, gps and switch for aux heater, then to put back with mods where plastic has broken over the years on fixings.

The wipers worked 3 years ago when put in storage but the shafts are very corroded.  Managed to drift one side out without damaging thread etc. polished all the corrosion off of the shaft and reamed the bush out from 14mm to 14.2mm, removing rust as well.  Can well grease and refit.   However, other side is corroded solid.  5 days soaked in penetrating oil, a big blowtorch (had to be careful not to melt aluminimum) has resulted in being able to turn the shaft just 20 degrees so can not even try drifting it out yet as need to make up a "long" nut or threaded metal to sit over the thread completely so load is on shaft not thread or tapered part...................hassle.   Found a relacement unit (new) in Germany for £70 so on the way and will see what quality before more work.

Don't we love cars!

Anyway, would be very, very appreciative of spare glow plug!   That will be last job done.  Have until MOT runs out on petrol car in November to get going!

Seem to remember you were Bath way?

Sounds like you are having a bit of a nightmare with your 3 motors,cars certainly like to keep us busy.

No probs I will dish out the plug tomorrow and get it in the post to you.

Did you ever find that glowplug?


Also, The petrol Galaxy I have is dying - both cills rotten as hell and will never pass MOT so having to scrap in November - Shame, but 21 years old......  Anyway, running OK now, but  lot of noise from aircon when (clutch on aircon) activated.     Need to pull the fuse for the aircon clutch etc. but no real clue from fuse list.Shows :-
fuse 3  heated seats, cruise, compass etc and cooling symbol
fuse 12 cooling & heating symbols
fuse 15 looks light aircon light as grouped with brake and petrol light
fuse 16 cooling symbol
fuse 19 washers,heated scrren etc and cooling symbol

This seems far to many - anyone any clues before I start fiddleing....or is there a connector near the aircon clutch I can just pull................

Yes I know should put it on....but on this model with rotary heating controls, turn setting to demist and automatically comes on!

Looking at TIS, fuse 18 looks to be the feed for the compressor clutch, and only feeds that. Should be a 5a fuse.

There should be a connector on the compressor clutch itself that you could also pull, but fuse probabbly easier to do.

No probs
is your pm working now?


Also any clues on disabling the aircon until scrapped.   I believe if I disconnect the pressure sensor, that will stop clutch pulling in and I don't care about anything else!!!Lights can stay on etc. etc.   Could pull plug on compressor but not sure if that will cause any other issues.   Only got to last 3 months and dont want the clutch to seize!    NOT exactly sure WHERE the low pressure switch is to pull plug - Petrol - 2001 - 145 bhp model


PS.  On previous posts re. dash and aircon on another Galaxy.  Seems there are two types of electronic a/c controller - both the same externally - but the pcbs differ inside - I have collected more from a couple of scrap Galaxys (good job my local breaker is good friend!)   Types with one pcb/fan only run the sensor fan when switched on.  The other pcbs/fan run the sensor fan as soon as ignition on - hence faint motor noise when everything else off......Took whole dash out to find this was in the control head - anyway, gave everything a good clean, so not wasted time.

Even looked a brand new Galaxy but they all have heated screens and I can not drive with one (As a private pilot think it ill to do with eye scans) - and unlike older Galaxys there are no plain screens available, even after market........................

All the best
John

Yes pm should be working now as I cleared the inbox out.

If I recall correctly the pressure sensor is in the offside wheel arch area? I would just pull the plug on compressor as it?s not going to have any effect on anything else.
The heated screens are a good idea but I am not a massive fan of them when driving anymore. I never really noticed anything previously but we have transits at work and since driving them a lot more over the past year after a long journey I get a headache. Never do in the car it?s only the van,I think it?s something to do with the heated screen. Can?t really put finger on what it is exactly but suspect I sub consciously focus in on the heated bars at times. Amazed you can?t spec a new one with a standard screen.

I really like the heated screens.  I can notice a faint shimmer in my vision when the screen is warming up (only on the Galaxy, which is also IR reflective, not the Mondeo) but all fine after that.  The refractive index of the whole sandwich must change as the wires heat the middle layer.  I can see the wires if I look for them but the screen doesn't (seem to) affect me otherwise.

Did fuse 18 not work to disable it? Otherwise as said pulling the connector off the compressor clutch will be easiest, but that involves getting under and taking undertray off (assuming its still there of course)

Hi all
thanks for help, sorry for delay - been chaotic here

No undertray - vanished at adealer years ago - so pulled plug from compressor......done
The old girl must know she is going to breakers in November......now dropped of the exhaust on me!!!!!    Band aid needed for a few weeks.

Thanks for all the other help.   Sprae Galaxy now running.  An HVAC pressure warning but should be easy to find.

Plus of course some door wiring issues to mend and solder.


Thanks all

John

p.s In West Somerset and now have heaps of parts if someone has any spares needed
