Aircon Problem on Saab 9000 CSE

I have a 1995 Saab 9000 CSE 2.3 Turbo. I bought it back in Jan 06.

I've noticed a problem with the climate control. It works fine as long as the outside temperature is below about 22C. However, above that temperature it starts to fail - so that the fan still blows but the cooling effect is lost. It also tends to cut out when I'm crawling through traffic (which happens a lot - I live in London).

It may not be related, but I have a temperature indicator on the dashboard and when I'm in slow-moving traffic the temperature goes up and up. A couple of weeks ago I saw about 45C on the dashboard when the outside temp was about 30C.

I took the car to an independent Saab specialist a few days ago and asked them to check it over. They said that the temperature sensor had been dislodged so they put that back in its proper place. They then checked the aircon system over and said that there was no fault in it. However, the problem remains so I'm not sure what to do next.

Does anyone have any advice/suggestions?

Thanks, Alan.

On the aircon ... mine had stopped cooling ... all it took was a fluid top up or something similar. Apparently standard stuff for air con units. I think SAAB in the UK have a standard price of around 80-90GBP to top up the unit.

I think what you feel up to 22 degrees is simply the coolness of the outside air (the same happened to me).

There is also a temperature sensor on the dashboard with a little palindromic motor inside it and a few electronic gadgets. [Note I think it is a temperature sensor it could be something else]. The motor costs circa 40GBP and includes all electronics. With time it becomes annoyingly noisy and then it probably stops working (I had two replaced already ... little crap things). The idea is it shifts air about over a temperature sensor etc etc. I notice you are uk based ... so you will find it in the centre of the console towards the steering wheel. It will have a perforated circle at its front ... like a penny in size. (Sorry I will go and look at the car if you need a better description).

Hope it helps a little.

I have just been through all sorts of hassle about air con on my

9000... Do you know if your compressor is coming on? If not you won't get any cold air! It has a clutch on the left hand side as you look at it with the bonnet open. It should engage when you set your air con to auto & low.

The little dashboard fan that samples the air also gets full of fluff over time, Take something small like a cocktail stick, and with the AC switched on GENTLY and SLOWLY insert it into the grid that covers the fan. If the fan is spinning you'll get a rattle as the stick hits the revolving blades. No rattle = fan not spinning. Either replace it or try blowing it out with a can of compressed air - sort of stuff they use to clean PC keyboards. From what I've been told if the fan is OK, and there's a leak in the sytem you are talking of megabucks to fix it.
