COSSY (1997) INTERIOR CONDENSATION

Hi all, I am having some heater problems with my Cossy so Ive set them out below!
1st - The heater does not work (just blows out cold air).
2nd - When parked up for awhile after driving (shopping) or parking for the night on returning my cossies interior windows have heavy condensation on them and are dripping wet.
3rd - The AC Compressor has packed up (I have purchased a 2nd hand Comp) but has yet to be fitted, so the AC obviously does not work.
4th - The Temp guage is erratic... it takes an age to move off cold but goes up and down also it will move near the top if I stand for any amount of time in traffic (Ive had to buy a small ceramic 12v heater that runs off the Cig Plug (Dooh).
Finally, if I leave the Sunroof slightly open to allow air in the risk of condensation is greatly reduced but I dont think this is a good idea?
Any help with this litany of problems will be greatly appreciated
Gerryw

Was it working previously?
is it using water?
sounds like you have a leaking and or blocked heater matrix.
Tried a reset?

And check these

The two heater hoses that go through the bulkhead, are they hot once its up to temperature?

Possibly the thermostat is stuck open too if its running cold?
are the cooling fans coming on when its overheating?

Check your footwell carpets for rainwater ingress.
The A/C is designed to rid the car's interior of moisture ( not just to cool the inside temp in summer ) so you'll need to get that fixed first.

removing the moisture IS what cools it

Hi GerryW --
I experienced the same. In your case it seems there is a coincidence of known errors which now accumulate.
1) Cossie's design has poor natural ventilation with windows closed. It does not have an automatic air release as in other cars.
Generally for good ventilation one needs an air current which by simple physics laws requires a sufficient inlet AND outlet - your Sunroof is ideal because of the natural chimney effect.
In this cold and damp wheather my Cossie - with the perfect Airco switched to OFF, heating ON and windows closed - will develop steamy windows in 5 minutes. Plain condensation.
My A/C therefore is always ON - summer or winter - heating or cooling - and perfect since it absorbs the condensation humidity from the inlet air. never a damp sterringwheel, never damp seats etc.! Use it always - Cossie has a SATC for a good reason.
2) Get your Airco fixed; a Cossie cannot do without.
3) Your engine's thermostat plays up. It is a very simple medieval device, which will suddenly give up or behave erraticly, easy to get at and replace below the engine, especially when the A/C job's being done.
Besides it affects the proper working of the whole SATC Airco system + influences your EEC-V computations and engine and autobox performance if failing!
Get it fixed or your troubles will persist.
4) Your instrument cluster plays up. Do you have funny open closures indications sometimes? Tripcomputer not responding? Does your airbag light come ON sometimes?
This is all due to eroded connectors at the back of the instrument cluster. Remove the dashfascia - it is les difficult than it seems, there is an execllent article on the website, just SEARCH - pull out the instrument cluster and spray/clean/brush all 6 multiplug connector strips. Bingo.
PS Do not forget to replace ALL LAMPS (about 12 or so!) when it's open and out!
5) As mentioned in this article get to the 2 tubes emerging from your A/C housing, directly behind the engine, and pull each waterdrain and clean/replace it.
http://www.fordscorpio.co.uk/acdrain.htm
This is a vital operation each year, even with a proper A/C as Cossie's natural ventilation is insufficeint. Wait for your engine to be cold!
Use a little loop to pull one difficult drain towards you. Send me a PM for details.
HTH, worked for me!

Need to disagree with some of that Ray,
I run a 24v with no AC and there are NO condensation problems with it, it wasnt standard on every 24v so they can do without AC.
ANY car with heating on and no AC in cold weather will suffer condensation until it warms up, its not exclusively a 24v or indeed a Scorpio condition.
Gerry only has a temperature gauge that is a bit erratic, he doesnt have any other erratic instrumentation so I dont think the connector is the problem or the dash needs removed, I suspect his problem is either a thermostat/cooling fans or just a sender unit problem but we need more info to determine this.

Big green relay in the engine bay down behind the drivers side headlight, check that first

There are vents to under the car each side of the boot behind the side panels,
air flows through the vents in the parcel shelf on a saloon & out through the boot vents.

Hi Tompion,
this is quite extraordinary news - since my Ford friends nor me were able to find these vents... and have blamed it on the design... would you please be of help and could you give us a more precise location description OR how to get to them?
Would they open up under the rear bumper?
We'd like to inspect them as they may be clogged or closed off...
Would you have a stuation plan or a sketch maybe?
Looking forward,
Ray & his Ford friends

Hi All,
I am really grateful for all your replies to my COSSY problem and I am slowly working through them.
I hope to be able to get the A/C system up and running as the 1st step in curring the condensation problem.
I am hopeful of getting a thermostat by the end of next week to go with my 2nd hand A/C compressor so that both can be fitted at the same time, then get it gassed and see what happens...?
I will keep all of you who posted answers to my problem up to date on my progress.
Many thanks
Gerryw

The aircon WILL remove your condensation Gerry BUT there is still something causing it

Hi Ray
They are plastic hang down each side and are covered by the bumper, but you can see them from underneath. If you turn the blower on full & reach under the bumper you should feel the air coming out, they point inwards & have a crude rubber flap that hangs down over the outlet.
