Wildfaye29 Turbocharged May 18, 2009 Share May 18, 2009 Hi, have the above prob on a 2yr old colt plus. 40k mileage. Initial dianogsis is the aircon clutch (magnet plate) spoiled. Was quoted $470 by a aircon shop in woodlands to replace a new one. Currently working intermittently. Gotta on/off again if its not cutting in/out properly. Has anyone come across this before? And if the quoted price is reasonable? If not, any other places where i can get it done at a better price? Any advise appreciated! ↡ Advertisement Link to post Share on other sites More sharing options...
Yeobh 4th Gear May 19, 2009 Share May 19, 2009 Don't jump into conclusion to change the air con magnetic clutch. First check yr battery and alternator for performance. Disconnect wire to magnetic clutch , increase engine speed and check voltage input to clutch - this will confirm whether there is a voltage drop or the relay is not working properly.

Munch003 2nd Gear May 19, 2009 Share May 19, 2009 (edited) I recently just got my aircon compressor overhauled in JB. The compressor bearings were noisy and there is a metallic pinging sound whenever the aircon is first turned on. Was advised to overhaul it. They opened it up, serviced it with new seals and bearings. Cost me RM240. After servicing the aircon is cooler and quieter. Overall satisfied with the money spent. Looking at the bill, they charged me RM35 for a relay. I am curious what is the function of a relay in a car's airconditioning system? Thanks.

Yongwd 1st Gear May 21, 2009 Share May 21, 2009 There was once my 18months Honda is having exactly the same problem like yours. I went to my parallel importer workshop to diagnose with "faulty a/c compressor clutch" I was not convinced that a 100% japan made compressor would fail with only 15,000km mileage. I thanked them and walked away when I was quoted $350 to replace it. I went along with my own diagnostic and observe the problem when the compressor clutches in / out during operation. I also connect a amp meter and voltmeter to the compressor measuring the current and voltage drawing from the fuse box and realized the problem happen when the a/c compressor relay is hot and therefore not delivering sufficient current, ie faulty contact Temporary swapped the relay from another car to test, problem went away immediately. $12 to get a new relay the next day vs the $350 quotation.

I have a somewhat similar problem with yours long time ago when I was driving another car. The air-con somtime was cold and most of the time was not cold at all, just blowing hot air. Went to a few so-called air-con specialists and everyone of them claimed that the compressor was gone and recommended me to replace it. I almost gave up and change it until a friend recommended me to see an air-con specialist specialising in Korean car. Was driving a Korean car at that time. One look at the air-con and he told me that the compressor was still ok and he immediately pin-pointed the point to a relay switch. The replacement cost me only S$8!!!!!. It was working fine after that. Unfortunately, the shop is long gone and I dunno where it has moved to. Edited May 21, 2009 by Redstorm Link to post Share on other sites More sharing options...

Byond 1st Gear May 21, 2009 Share May 21, 2009 relay cost less than 10$... the higher cost is due to labour charges... Link to post Share on other sites More sharing options...
Yeobh 4th Gear May 22, 2009 Share May 22, 2009 Disconnect the wires ( with push -on fitting) going into the clutch. Make sure you get the live and ground wire correct, then use a jumper wire to feed 12v directly from the battery. If the clutch close and hold in position , locate the relay ,trace via the clutch wires and replace with the similar unit. Link to post Share on other sites More sharing options...

Yeobh 4th Gear May 23, 2009 Share May 23, 2009 Since you are not familiar with auto electric and do not have even the basic tester & tools, I strongly suggest you leave the diagnostic work and replacement to qualified auto electrician. Trying to save money you may end up with more problems that may be cause by your mishandling. Link to post Share on other sites More sharing options...

Xtc_exist Neutral Newbie May 25, 2009 Share May 25, 2009 might be due to the gap between the magnet getting wider due to wear and tear. Link to post Share on other sites More sharing options...

Wildfaye29 Turbocharged May 26, 2009 Author Share May 26, 2009 had e a/c fixed @ e ubi shop mentioned in post #5. replaced e magnetic clutch, re-gassed and had the relay replaced @ $110 + GST. happy w the job done, the clutch engage sound when a/c switch is turn on/off has also gone away, prob a worn clutch. the supervisor oso mentioned that i have a C-fresh a/c filter installed recently, asked me to avoid such aft mkt filters as they restrict air flow and will oso cause other probs in future. asked me to stick to stock. any other views on this?

Zoom99 Neutral Newbie May 26, 2009 Share May 26, 2009 Check the compressor. If excess oil accumulate on it, then you can kiss goodbye to compressor. Link to post Share on other sites More sharing options...
Tas0577 1st Gear May 26, 2009 Share May 26, 2009 Guys, I was told by one of the air-con specialist that it is best to put the air-con temperature setting at the maximum coldest as when you put near to the Hot zone, it will mix with the hot air from the heater core and it will produce some funny smell at certain times. Is it true? How many of you really put to Maximum Coldest? ↡ Advertisement Link to post Share on other sites More sharing options...
