98 vectra air con - steveh67
today i just pressed the snowflake button ,it lit up but nothing happened , i noticed that when i got home i let it idle on the drive then turned it on again, normally theres a slight pitch in the way the car idles when the air con is switched on... but nothing happened!
Any ideas Guys ??
is there something prone to faults on this unit?

do i need a re gas??

all help appreciated

Regards Steve

It probably won't operate at current ambient temperatures.

Try it again when temp. is >5C.

Sounds like it's low of gas to me.

When was the last time it was topped up? If recently, then *hopefully* the person who did it added an ultra-violet dye to aid leak testing.

I'd start from frostbite's suggestion. Most a/c systems cut out in low ambients, presumably to reduce risk if internal icing. If it's still u/s when the oat is over 5C then its time to worry about malfunctions.

Hi, I did 86000 miles in a '98 Vectra V6, never noticed lack of response from the aircon at low temps, it did however lose it's gas once.

I have a similar problem

I'll be off down the motorway this weekend and I'll leave it to idle on the drive at the end to see if the cooling fan actuates or if I boil over - but it does look as though its still all gone despite my fuse and connector cleaning.

There may well be a problem, but it's correct that Vectra a/c won't work below 4 deg C ambient temperature. I recall this was in the handbook of my 1997 2.5 V6 SRi, and that it is to stop the evaporator freezing.

Have you had a look at the fuse in box under the dash and the two fuses in the rectangular box just in front of your right hand when you open the bonnet. After that have a look at the advice I got [link in the post above in this thread]. I have to admit to getting fed up with cold wet maintenance and having taken it to the dealer - its only money after all.

Money gone - car fixed. elekie&a/c doctor was almost there - thanks [see link to my thread above]. The problem was a broken wire caused by fan front of radiator rubbing it - It had not been properly positioned following previous repair. Aircon will be dead handy tomorrow - they have forecast -4C.

Good luck steve
