Car problems - need advice

Found 28th Dec 2014
Got an old 2002 Citroen Picasso. Lately i am having some trouble with my windscreen misting up, it happens more than usual. The vent is struggling to clear it up (the air conditioning is empty so I can't use that). Also when i put the vent on, there is like a smell of "engine" coming in the car (hard to describe it really). Has anyone had the same problem in their car? Thanks

When was the last time you had the cabin filter replaced?

There may be a blockage of debris (rusty sludge) in your radiator or pipes. Drain the system and flush it with a garden hose.

Sounds very much like the heater matrix is leaking, not an easy fix unfortunately as the whole dashboard needs to come out I think, you could try one of the better (if there is such a thing) rad seal type treatments.

check to see if the carpets are wet in the floor wells.

Is it blowing hot air? Sounds like you may have a small leak in the internal rad used for the in car heating. Is it loosing any water from the main rad? If so, as its quite an old car I would give rad weld a try, you can get it at most accessory shops, you just poor into the main water bottle for the radiator.

A blocked cabin filter would restrict the air getting through the vent like you describe, easy fix if a bit fiddly to get to.

I would check all the carpets to see if there is any moisture as this would collect on your windscreen making it more difficult to clear.

Is it blowing hot air? .



This is the first thing we need to know, if it isnt it could be a number of things, thermostat, radiator etc.

Thanks guys, not sure when is the last time the "cabin" filter has been replaced (do you mean the pollen filter?)I will have to check with my mechanic if it is something that he replaces when it does my service. If anything when i put the heater on it is extremely hot. I haven't checked the carpet, but i don't think they are wet.

My partners windows mist up a lot as he had a leak through the aerial and water got in and due to the season it hasn't been able to dry out yet. Also a woman I work with used one of those frost free windscreen cover things you tuck into your doors/windows and her car, a tigra I believe, didn't seal properly at the windows and water got in, resulting in the same problem. Hope you figure it out!

On the newer cars the ac is used to demist the car as well, in the audi i had and the rav4 you could switch off ac to save fuel but at a cost of the windscreen remaining misted up unless you have heat on full blast all day long.

I don't have any AC, it needs a refill and I never bothered getting it done. I will check the cabin filter tomorrow and replace it if need be and see what happens

When it's cold and or raining, I simply turn on the demister, but I set it to the lowest warm temperature and at the lowest power. This is the best way to 'save fuel' without sacraficing your view and also keeping you warm. Surely it works on most cars as I've tested it on a LOT of different cars.

An update just in case it can help someone that may have the same problem. It was the heating matrix (Dyxlexic Dog and Argoj were right). £120 labour (could have been cheaper i guess if I used my other mechanic), and £33 for part, thus I was quoted initially £78 by another shop. Car is perfect now

I'm glad you got it sorted out ok, and that sounds like a very good price to me, especialy as there is a fair bit of work involved to change the heater matrix, just check the carpets in the footwells are dry now otherwise they can start to rot and smell rather unpleasent.
