A/c It Works!

63 posts in this topic

@ Bessyyes these are the kits iv been using for years. i bought the kit about 4-5 years ago to recharge my explorer. but iv used it on many cars an work trucks in that time. i buy a can or 2 in the spring an when i find an ac not working up to par i put some in. i dont ever plan on taking my car into m-b for ac service so i dont worry about them hooking into my system. if you know where the leak is at you might be able to get a rad shop or intercooler shop to repair it.

I think you will find MB won't work on the car if you use aftermarket gas. It will contaminate their equipment. The system is "supposed" to be sealed, closed. I would be amazed if they replaced lines if you aren't going to let them do the evaporator.Lack of coherent policy when fixing these a/c systems is one of the reasons I gave up on my smart. Sometimes they pay the whole shot, the next person gets a partial repair, and so on.It is a very poorly designed system and they should be ashamed of themselves. They aren't.

I told my MB dealer that I had recharged my system with Duracool & they still paid the whole shot for new lines plus evaporator.I also told them I had pumped the system out with a home made vacuum pump as part of the yearly recharge don't know if that made a difference or not.

Lines changed today! Free of Charge...finally. The original quote said we needed lines and an evaporator, MB Canada would only cover the lines, the Evaporator would be $1600 to us. So I booked it in for just the lines, Day 1 and A/C is Ice Cold...and no smell inside the car like a leaking Evaporator would.I have a theory that the lines going to the Evaporator were leaking and that caused a misdiagnoses. I will keep informed if the A/C loses it's coolness.

Mine was also done last year, post-warranty. The process at my dealership was:

[*]inspection re complaint: blows warm air

[*]leak check

[*]recharge and test now cooling to spec - n/c

[*]customer drives car until system fails and gets warm again (it was a few months)

[*]re/re lines and dryer - n/c

According to the Ops Manager, this was a cross-Canada roll-out from 2010/early 2011, of revised line-sets as "permanent" repair for earlier design.

So far, so great this spring!! You have a good relationship with TPM, Mike; should be no problem for you.

We will see, the email is sent. I am not optimistic.

We drove out to Niagara/Hamilton (250km round trip) yesterday 25+celsius and sunny. The A/C performed ok, there is definatly still a leak, I'm hoping it's small enough that some leak fix might do the trick.Side note on the quality of work, I had to re-insert the ABS Sensor wire into the holder (they lowered the engine to change the lines) also for some reason the e-brake lever rattles now.

When lowering the engine the e brake cables are detached and then sometimes the whole assembly slides out.If it's not right I would take it back to the dealer.

Finally got hot enough in Winnipeg (briefly) to need the A/C. Still blows nice and cold, so far so good. Good to hear that some of you have been able to make the case for MB to provide the "permanent fix" gratis or close to it.Maybe I'll just start taking it for granted that the A/C will be there when I need it (just like my other vehicles)...novel concept I know.

@smart142The e-brake works fine, the rattle seems gone now too. I went to check the oil and found the engine cover wasn't secured...I swore I smelled exhaust on our road trip. Deffinatly not interested in going back to the dealer unless it's something really wrong (long wait, not top notch work, broke our fragile key, and the nicest person there was the 17 year old kid that was our shuttle driver)

some dealers employees are great and take appropriate care with customers vehicles, others couldn't care less.Nothing new...my first 'new' car was a 1977 Chevy Monza Spyder with 305 engine.Took it to the Durham region GM dealer I bought it from for it's first oil change, young mechanic got into my car in the front lot anddid a burnout from the front all the way to the rear service bays.I was standing in the showroom having a coffee with the sales manager and we watched him do the burnout.I got a few free oil changes out of that...thought the manager was going to stroke out.....I prefer to do my own work whenever possible.I am going to take it to my indy who actually cares about people's cars.Have him vacuum the system and get an idea.

Mine blew warm this spring also. I brought it into the dealer as it is still under warranty. (For another 10 months or 17k) They told me they don't think my warranty covers lines but would look into it. I told them about the updated lines but they looked at me like I was speaking another language. (Kinda the same way they looked at me when I told them about the intercooler now that I remember it.)They charged it up and put the dye into it. Then told me after that they couldn't find the leak and to come back when it blows warm again. Then proceeded to charge me $120 for their troubles and sent me on my way. I'm not totally happy with this. Not sure what my next action will be at this point. If it manages to last the summer I know it'll blow warm next spring when the warranty is up.Any advice?

The next time it blows warm air take it to the smart friendly dealer in Oakville, only 109 km, 1 hour 22 mins away. :D

It is unfortunate that each dealership seems to be able to approach this differently; from my perspective there should be a standard policy on dealing with the A/C design flaw (i.e. fix it permanently with the proper solution and don't charge the customer). I have always had great service from Lonestar Mercedes in Winnipeg and they came through for me on this issue too. I don't know if this will help you but they told me there was a "sweet spot" when it came to getting Mercedes Canada (?) to approve the permanent fix at no cost (having said that I was told that if Mercedes Canada did not approve it then the Lonestar Manager would recommend the fix and then Mercedes Canada would have no choice but to go along. I am not sure if that is the way it works, others in the forum may know better, but to me it indicates that each dealership has some ability to help you out even if "Corporate" initially does not approve.)What I was told concerning the "sweet spot": Mileage is relatively low on the vehicle (mine was around 50,000 K at the time) You had bought the extended warranty (I had the extended warranty). The A/C had a history of failing (my A/C failed every year since I owned it).I don't know what your circumstances are but if you are in the "sweet spot" ballpark then I would use this as the argument for getting the permanent fix (all of it) done at no charge. From some of the posts it seems that others have managed to get the fix done without meeting the above criteria so, again, there does not seem to be any rhyme or reason. I would suggest also that you keep at them and document what has happened so that when (if) the A/C fails again you can quote times/dates/conversations as that seem to provide some support for your case. Don't know if that helps but good luck.

I have been told that my green car with its high km will get an A/C repair. It goes in next week.My thanks go out to Three Point Motors and to Mercedes-Benz Canada.

We got the car back on Monday, she blows cold as ice and I hope will be good for a few more trouble-free years! Again, thanks to TPM Victoria and Mercedes-Benz Canada.

Erratic and inconsistent repair policies by Mercedes is why I sold my smart. I only had 60k, was original owner, full MB service record, extended warranty. I shouldn't have had to find a more forgiving and reasonable facility. This is a known problem, was for years.I won't be buying from them again.The Fiat is wonderful and the Volt is amazing. The Ranger soldiers on.

My wife's 06 smart was blowing hot air. I went over to dealer today because previous owner had had a/c "fixed" in April 2010 about 3 months before we bought it. It was one of the reasons we bought the car. It worked OK last summer, but not now. When they "fixed" it, it was using original design. Anyway they will look at it next Monday and then submit claim to MB. Mileage is just 55k and we have three other MBs (albeit old ones!)We will see how this goes!

Spring ritual for me ... but last fall they replaced the 'lines' with the new improved version ... no charge to me...This spring.. no air , as usual, same as the past 5 years :-( Put in new air compressor (no charge to me) last week... No A/C a day later :-(I would be really upset if it weren't for the fact that the dealer has been excellent throughout all of this... They loan me C-250's to make me feel better :-)

The fact that dealer repairs don't work for long doesn't give me any hope we can resolve this problem. Dealer said to me today that the diesel vibration could perhaps be reason couplings fail.I was wondering how an independent A/C shop might fix this. Maybe they could install flex hose connections or something. I haven't looked to see just what the problem is that causes these regular failures.

Diesel vibration plus a completely inaccessible o-ring design IS the cause. The offending o-ring fitting has been redesigned in the upgraded line set. A better grade of flex hose sections from the engine to the hard lines has also been fitted, I believe (might be wrong on this).There are a few things that can be done to reduce engine vibration (amplitude) but the trade-off is more vibration to the occupants. Stiffening motor mounts, for example.I am holding out hope that the last dealer repair to my a/c (new line set) will hold. My next step will be to switch to DuraCool or RedTek with their larger molecule size to reduce leakage - have it professionally installed.We must also keep in mind that once the line sets have been replaced, it is still possible that they have not taken the time to properly detect leaks at other points!B :sun:Oh, and... an independent auto refrigeration specialist could totally replace the hard lines, front-to-back, with composite or flex copper lines to completely isolate the engine vibration. Might be costly... :dunno:

If you wound up having to pay for new lines, I wonder if it might not be possible to modify the a/c system to put an electric compressor in, I know it wouldn't be easy ( or maybe even possible/feasible ) and haven't really investigated it too much, but thought about it when reading the thread about the smart converted to all electric operation, and thought you might be aable to put one up front , so short lines and away from engine vibrations. Probably would take too much work, and be too costly even if possible, but thought I'd throw it out there for discussion.
