paulfoel Posted May 21, 2018 Report Posted May 21, 2018 Was working fine earlier today. Now its just blowing same temp air. Display says on but it makes no difference. Anything obvious to check? Quote
gregers Posted May 21, 2018 Report Posted May 21, 2018 is the display flashing at all?try and read up on air con within the faqs found in the technical section of the forum. Quote
BrianH Posted May 21, 2018 Report Posted May 21, 2018 You don't say which one of the galaxy's you have, Some of the diesels have a pipe that can snap, the mk2 has an occasional slow leak by the dryer assembly. Can you hear it clicking the clutch on/off (loud clicking from drivers side end of engine). Any signs of bright yellow oil under the car? Quote
BrianH Posted May 21, 2018 Report Posted May 21, 2018 Also road debris can hit the condenser and puncture it. any damage of that sort could cause it to suddenly stop due to lack of gas. though would expect you'd have heard it happen (I've had a hose pop off under the bonnet where the spring failed, it made a noticeable bang on doing so, and the smell of gas was noticeable for a few minutes afterwards) Quote

BrianH Posted May 22, 2018 Report Posted May 22, 2018 If you can find the aircon pulley (its the lowest one if its a mk1 or mk2 your posting about, closest to the front end of the car) see if you can see the central spindle on it turning as you click it on/off. If it appears to be clicking on/off check the temperature of the pipework either side - one side should be hotter than the other if its working. If that is the case then it may be a fault with the flap mechanism inside the heater box - If you can feel the pipework round that area again it should feel cold to the touch. Quote
paulfoel Posted May 24, 2018 Author Report Posted May 24, 2018 Took it to Halfords autocenter (yes I know but its close to work). They put it on machine and it showed ZERO. They are saying its empty. But I said it cant be because it works intermittently. They want me to bring back tomorrow so they can use nitrogen to test for leak. Tempted to let an air con specialist look at instead to be honest. Quote
BrianH Posted May 24, 2018 Report Posted May 24, 2018 Check out the dryer cap - it will take you about 20 minutes to get to it, its accessed from the front grille area. I've filled mine with Araldite as the cap wasn't shifting, its held for 6 weeks now without a problem. (others have used hot melt glue and reported success with doing so) Otherwise if you get it regassed it will work, but only until enough gas leaks out to stop it again. The correct way to fix it is to replace the unit, and replace the dryer cartridge every couple of years, but my experience with aircon is the more you distrub the more of a problem you cause!. A/C specialist might be worth a try, I don't know how far Halfords AC will go into it, would suspect it may be a case of leak test and either confirm it leaks or can't find any leaks. Quote
paulfoel Posted June 5, 2018 Author Report Posted June 5, 2018 Compressor buggered.... Jeez. £500 fitted - seems a bit steep. Although I guess it all needs to be re-filled afterwards? Worth getting hold of 2nd hand one from scrapyard? Or are there too many different versions? Quote
