Climate Control Reset

[scorpio_man]

hi there

 

is there a way to reset the climate control unit? or does dis-connecting the battery do it?

 

to give you an idea, i've had the flashing dash panel. i got it re-gassed and that fixed that, but

the compressor still isn't kicking in.

 

it might not have the correct amount of gas as it's the 2 zoned version. the sticker says 1= 750g, 2= 1050g.

is that 1+2? or just 2? that's what they filled it to.

 

on my other car (ford scorpio), we can reset the system (homing the flaps, etc.) and run a diagnostic routine on it using the dash.

 

any help appreciated.

The compressor should kick in when the air-con is switched to auto....the drop in the engine revs is quite obvious as is the sound.

 

If not then it is most likely to be a problem with the compressor not the Climate Control unit.

 

You have the correct amount of gas ( assuming they filled it correctly ) the lower value is for front air-con only the higher is if you have front and rear aircon.

 

Not aware of any diagnostics that you can run on the aircon without using an analyser or similar.

hi there

 

thanks for that. i got it filled at kwik fit as they do a 'getter lower by 10% or you don't pay'!

 

i phoned my usual a/c guy and he thought the compressor as well. strange, there's now a bit

of a whine sound after the gassing, not before it.

 

over to the a/c guy then. :lol:

 

btw, this is what i can do on my scorpio.... http://www.fordscorpio.co.uk/ccreset.htm

Are you sure its the 2 zoned version?

 

The 2 zoned version can be identified by rear roof mounted vents and electric rear quater window only on one side. Both versions have a control unit with front/rear temperature controls and display so don't be fooled by that.

 

If as I suspect you have the standard single air con, then the correct quantity is the lower - 750g (check that label - mine says 950g ).

 

If it is overfilled, the 3 way pressure switch prevents the compressor operating.

 

The 3 way pressure switch is a low/normal/high affair. You can bridge this out but you stand damaging the compressor if the gas quantity is wrong.

hi there

 

i think you might be on to something there. i thought it was 2 zoned as it does the

front and back, but doesn't have any roof vents. sounds like it's over filled!

 

i've one of those diy kits in the shed. i must check to see what pressure it's reading and

collect some gas into a spare car.

 

that should do me until friday so i can get to my a/c guy.

 

thanks again for the replies.

ps. i'll have another look at the lable in the morning.

hi there

 

i've had another look at the fill sticker.

 

it says 700+50 for the 'normal' 1 climate system.

 

can someone confirm this is correct for a 2000 (x-reg) galaxy.

 

cheers
