When it rains,the windows of my V6 steam up bigtime! I've got aircon, and I've used Hi & Lo temp. settings set on screen demist; manual overide on full speed;the side screen demist is non-existent, unless I use the face level vents turned towards the side windows. I've tried using recirc.air setting,everything I can think of! The rear screen demist works OK....but all other screens WILL NOT CLEAR! Never had this problem with any other car.Try driving it in the dark when it's raining!! Does anyone else have this problem?? :confused:

Hi Steve,

I had a similar problem with my 1.8 8v.

But my problem had to do with lack of power in the ventilation system, my blower worked properly, but there seemed to be a blockage in the vents. So there wasn't enough ventilation power to demist, aircon etc....

My evaporator was in desperate need of changing, apparently a common problem with 155's, 145/146's etc.....

I had to take it to a local specialist for changing as you need to remove certain lower parts of the dashboard.

All working properly now !

I hope it was of some help.


Regards,
Eric Caruana.

Hi there Steve,
Have you tried to use the demister together with the "Auto" button on your aircon. On my car this is the only setting to keep my windows absolutely clear in raining conditions.

Unfortunately I think the answer is that the demisting on 155's is simply pants. I've driven a number of different models and they all suffer in the same way until there is some heat in the car.

If anyone has some modification suggestions, I would be interested to hear them.

Hi Steve W

I had the same problem (i too have electronic climate control) the fault was a defect servo for recirc. the recirc.-function was on all the time and the car steamed up fast.
You can check if the damper works by looking down the air intake, in order to do so you have to remove the wiper-arms,the plasticcower underneath and the fresh-air filter, then you can see the damper.

If the servo is defect you have to remove the radio, ash-tray, climatcontrol panel, all plastic around those, glove compartment, a hell of lot of screws, ect. ect. ect. (about 3-4 hours work)to get to it, the servo is located "under" the front right speaker (but you can't reach it from the top)

Good luck ;)

Alot of misting I find generally occurs because there is constant moisture in the car generally when the car is damp on the carpets ctc.and letting in rain.

Thank you all very much for your replies; now I know I'm not the only one who's had these problems. Keep on keeping on!{in a 155, naturally}.

Hi all
I know its a bit late in the day to be replying to this but on my 1.8 TS 16v the best way to de-mist the windscreen is to turn the air direction knob to the footwell setting and close all the vents!!! This works far better than doing what the handbook recomends!

Hi Ian,

I agree, I get more air up onto the screen if
I set the direction of airflow BETWEEN footwells and screen

Raj & Ian (and others!)

I reckon the logos on the controls for the heating are wrong - you'll find that footwell & screen logo's are reversed - turn to footwell & screen will clear, turn to screen & tootsies get warm. My wife worked this one out!!
