Condensation Arrrg !!
« on: December 13, 2020, 02:43:49 PM »
Has anyone any ideas as why i get so much condensation it's worse now in the cold wet weather.Its becoming a nightmare if more than one person in the car.In the summer its not too much of a problem as the A/C sorts it out but
 of course with the lower temps it doesnt kick
 In . I've tried various combinations of heater settings but no real success.Theres no damp or wet on the carpets etc,its just driving me nuts now.any suggestions welcome,thanks

What’s the pollen filter like and water pooling in the scuttle area? Also check the heater box moisture drain isn’t blocked.
Finally is the recirculating flap working properly as a defective flap staying closed would also cause that. You can probably see that through the pollen filter housing

Yeah just force the AC to switch on and that should do the job

I also find that opening the windows a bit usually helps
I drive a Seat Alhambra 1.9Tdi which has 115bhp and an automatic gearbox.

I am happy to help you with all your questions. I am not a qualified mechanic but seem to be better at fixing my car than even the most experienced garages.

I have lots of friends here and very much enjoy talking with you all.

Must admit not  looked at the pollen filter,not a nice thing to do in this weather.The AC is designed not to work below about 6c.My Passat was always crap with condensation too.Maybe its just a VW thing,do all makes disable the AC below a certain temp ? just curious if anyone knows,anti mist stuff is pretty useless too.

Majority of climate control cars disable air con below 6ish degrees to prevent freezing and liquid refrigerant getting back in to the compressor. Later systems like in my bmw do not have magnetic clutch compressor they are variable displacement type controlled via pwm. Even when switched off or cold outside they typically run at 5% to prevent seals drying out causing leaks I assume this helps with misting up windows aswell.

On my old galaxy I didn’t really suffer with what you are so would be inclined to think there is an issue like damp pollen filter or something

I find during the winter it always helps to park in such a location that my car is facing to the east (gets more sunlight in the morning to warm things up)

It’s been a while since I had my mark 2 but I think it comes out of bulkhead around the centre low down to front of transmission tunnel. Small rubber hose with a little cats arse type valve on it if I recall correctly.

Do you ever have to top up coolant? I had a slight leak on the mk1 from the heater matrix which left a greasy film on the screen and made it fog instantly when it was on the hot setting. Though if you have coolant in the system, you should notice the smell of it.

No fluid loss at all ,always been a bit foggy,not so much in the warmer weather when the a/c sorts it out, I'll try and eliminate the suggested possible culprits.

Ok so it looks like I've more time on my hands now over the festive period than i anticipated probably like everyone so have ordered a pollen filter.Just been reading the excellent write up by Mirez so it  looks to be just about  within my limited çapabilities .The question is on my previous car the scuttle because of age and its composition was extremely brittle so it was a known fact that nine tomes out of ten it broke when it was wiggled out.Does this apply in this case,anyone had any similar problems.I had the good sense to pre purchase one in that instance.Im one of those that usually ends up with a disaster.

Theres a bit of a knack to getting it out, though even mine which i can only assume is the original one, isn't particually brittle. It has lost the outer edge of the hole on either end, but a large washer takes care of that.

You may find it helps to get the wipers to point vertically up the screen (switch them on then stop them by switching the ignition off) as i seem to remember it gives you a bit more space to work with.

While your there and with the scuttle out, check that there isn't water collecting there. As thats a likely cause of your issue.

Thanks Brian, that's reassuring.I remember when i had to remove the wiper arms of my other car,equally elderly but not a Bammy they were an absolute bugger to get off, i bent a friends removal tool before having to revert to brute force twisting of the arms which i thought were going to snap but didn't.

You don't need to remove them (the wipers or arms), just operate the mechanism from the switch to make the lower bits move around to make more space. Take the scuttle out first and you will see what I mean. The only bits you actually take off for the pollen filter are the scuttle plate (the lower long surfboard like bit above the engine and expansion tank but below the wiper linkage area  with the 3 bolts holding it in place) and the pollen filter housing itself (which slides out once you unclip it).

I found once bolts on scuttle were removed if you lifted up and pulled towards drivers side it would wiggle free. The pollen filter is a bit of a faff given it’s location. But follow the guide and you ain’t have much trouble.

Removing scuttle - https://www.fordmpv.com/smf2/ford-galaxy-common-faults-and-problems/galaxy-bulkhead-extension-(lower-scuttle)-removal/

This shows the scuttle drains and where to clear them from (ignore sunroof bits if you don't have a sunroof) https://www.fordmpv.com/smf2/ford-galaxy-common-faults-and-problems/galaxy-mk1-mk2-sun-roof-drainage/

It looks like the a/c drain is through the front of the car (check number 4 on attached diagram)
https://volkswagen.7zap.com/en/rdw/sharan+syncro+4motion/sha/2004-406/8/820-820020/#4

This would be somewhere on the bulkhead, Not had to play about with that myself so can't confirm that one, but would expect you should see it somewhere up the back of the engine. Might be easier to find by switching A/C on for a bit then looking for a drip from it. Of course you will only get that if its not blocked to start with. I've always found it mists up a bit, but usually keeps clear enough with the heater on (can't use the A/C on mine as its got a leaky evaporator which needs replacing first) or the heated front screen. Side windows are more of the problem for me.
