Sand in A/C

Sand in A/C

Postby Colossal on Tue Dec 29, 2015 11:12 am

Morning All,

Did a bit of beach work recently and got a whole bunch of sand into the A/C, now I know how to fix it after the fact and where and how to put a cabin filter in but my issue is how to clean out all the sand currently in the system. Anyone had the misfortunte of this happening and how did you clean it out? Please be specific with detail as the old "I think" this is how its done is not helpful.

Hey Mate, it is a massive job :(

I cleaned all the dust out of mine, here goes;

1. remove the centre top cover and radio etc
2. remove the next panel housing the heater controls, undo all the controls and wiring to take out of the car.
3. remove the lower centre dash completely
4. remove the pillar covers
5. remove the instrument panel and cover, take out of car
6. remove the glove box and passenger airbag, carefully !
7. remove the dash, take out of car.

You can now get to the top of the box that houses the heater and condenser cores and vacuum all the sand out. The fan itself can be removed and cleaned. I was surprised how much dust was in mine and cleaned the whole system including all the ducting.

Just to prove I did this ;)

OMG, Thats way more work than expected!
Think most of my sand is still on the window/top of bonnet side.
Only an issue when I go around corners.

Has anyone pulled off the vent between winscreen and bonnet to clean out this area? Im only asuming this is where the sand first entered the system.

You should be able to hose the sand out from above the bonnet.

As far as I know the air enters near the top of those ducts, it would have to other wise water would come inside every time it rained....

Is that how you cleared yours out? How effective was it?

The best way I have found...

Open all windows and vents up, set to straight thru/fresh air - and find a big straight road and go flat out, finding a big downhill is even better as you go faster. Foot to the floor, don't back off.

The sand will come to greet you, although probably best you wear goggles.

Build us a sand castle after please. 8-)

I have had the same problem.

100km/h all windows down fan on flat out...

It will eventually go. Still had sand coming out for a couple of weeks. All gone now..

Have fun.

Is there any way you can pipe a leaf blower into where the sand got in and just leave it running whilst engine is on and vents maxed? Or an air line from a compressor?

Must admit though, driving flat out down a hill with goggles on sounds fun

I've just used compressed air blown into the vents and cabin filter compartment and then dust out the rest of the cabin with the air before normal vacuuming.

I remember Fraser Is. sand was still appearing in various spots two years after I had the Rocky out there. :lol:

OK, after actually doing the job its REALLY easy, wipers off, dozen clips off, plastics between bonnet and windscreen off and blow out. Take fan out behind glovebox (bottom entry, another dozen screws) too and the rest of the crap falls out there. Cut out plastic and install cabin filter problem solved. Some people seam to be making this way too hard.

I spent a week on Fraser over Christmas, and I have a cabin filter fitted. Pulled it out when I got back and it was full, sounds like it may have payed for itself.

Just get a feminist to sit in the passenger seat, the sand will be attracted to her vagina.
