hi all. just a quick question. picked me car up thurs and to cut a long story short there was no gas in aircon. so today at work i managed to get it topped up.it seems to of hold the gas ok but when the engine is running with aircon on the fans are not running. then after a min or so they cut in full blast for about 10secs. so far i havent suffered from over heating probs to. ive tryed a search but found iit hard to get a straigh answer. any help would be great.cheers. rich

Possible fan prob?

My fans come on/off with the aircon button. I would think your's should do the same so you may have the ever popular fan problem
so they should be running as soon as you turn it on. i thought they did because i tryed me cousins focus and his run constantly. i know its a different car but should have same principal. what kind of probs do the have with the fans?
Yes as soon as I switch on the aircon my fans fire up, but I do have the mime modification so may be different from the norm. Probably best to check this out or search on here for cooling fan problems.

Taken from another thread:-
Basically, you have a two stage fan....or two fans
The water pump fails or the stat sticks so the fan cuts in and out on slow speed to control the engine temperature. You eventually burn this speed out.
The air con runs slow speed when it is engaged.
Once slow speed is burnt out the fans will cut in and out on fast speed, of course AC has to do the same thing to control system pressure....eventually that burns out too!
This is just down to the load on the fans!
I say fan speed one and two...it also works on fan number one and two if you have twin fans!
The source of the problem will be the cooling system.
I would also advise you check the fuses under the battery cover, is one fuse holder looking "melted"?
Make sure the ac ambient is above four degrees as below the ac will not cut in anyway...its all linked!
