Air/Con Repair

[Larz]

After three days with the Q50 Red Sport loaner, the dealer picked it up and returned my car today! Initially, they suspected evaporator problems, but testing proved it was the compressor, the mount, and some kind of collecting tank that also caused a fault in a temp valve. I have no clue what any of those things are, but it was unsurprisingly very expensive. They also found a very slight leak in an O-ring. Here is the breakdown:

Compressor 807.81

Compressor Mount 248.36

Tank Assy 312.43

Compressor bracket 68.21

Mount bolt 9.80

Temp Valve 98.20

O-ring 11.86

I have officially surpassed the cost of my warranty ($3,200) from CarMax. I still have complete coverage until Sept 18 2019 or 150,000 total miles.
Today my mileage is 104,000, so I will definitely get to the end date before I reach 150k miles!

Nice. Good stuff.

Hi: I'm Al. I just had my A/C Compressor & Condensor replaced by my mechanic and it cost me $982 for parts and $488 for labor.

Well my A/C compressor just stopped coming on, lets hope it's not nearly this expensive lol

Good point! If you use a non-dealer shop with a qualified mechanic, purchase non-OEM but perfectly good parts, and you can avoid the higher labor fees that dealers charge, you can save lots of money and get the same results. My car has never been serviced anywhere but the dealer and has 100% Infiniti parts - only because it has always been under factory and extended warranty since 2009.

Not sure if you have fixed this already or not but these cars are famous for having the electromagnetic coil go out on the AC compressor clutch. I have a thread about replacing it on the DIY list.

Hmm..interesting! I think I saw your thread awhile back, what exactly is the electromagnetic coil?

I want to fix this but it isn't a priority yet, but by feb/mar it will be I'm sure

my car used to have problems with the A/C compressor randomly cutting out if it was REALLY hot outside, or if I hit the throttle enough to make the A/C compressor turn off..it would not come back on for awhile(hours, maybe even next day)

It was working fine then previously, then I got back in the car a few hours later and it wasn't working, hasn't worked since lol

Edit: just looked it up, doesn't look too bad to replace the coil, only thing is Idk where to buy one lol

If you haven’t gotten to this yet, lemme know. I’ll be in here a little more often for a while. I have some neglected-care stuff to do on my car.

I haven't done it yet, But I did see your write up. Im going to tackle this in the next few weeks. It hasn't been super important not to have a.c. in the winter, but its going to be heating up in a month or so

.......It hasn't been super important not to have a.c. in the winter.........

True, but do not forget the A/C system is designed to keep seals & components lubricated by carrying oil to the varies components in the system while the compressor is operating.
Upon shutdown, the oil migrates to the lowest point possible, depriving seals & components of lubrication until the next time the unit (compressor) is turned on.
The only time these components & seals get lubed is while the compressor is operating.

This is why modern systems utilize the compressor during most cycles regardless of actual temps needed to provide comfort. They engineer the system this way to insure components & seals stays lubed.

All the above... Plus remember that A/C is not air cooling, it is air conditioning. And that can happen at all temperatures, if your AUTO system is working as designed.

Absolutely, I'll get it fixed soon!

Well my issue is my compressor doesn't come on, everything else is fine though

[Sstupid]

I would add to that DIY that I posted, to go ahead and unbolt the compressor from the block. After replacing the entire compressor, I realized it would have given me more room to maneuver.

[LIBRILZ]

Interesting, thanks!

The electromagnetic coil replacement, with the compressor in the car is HORRIBLE! Easily one of the worst things I've worked on, on a car

Biggest note? If you're going to tackle this job make sure you have snap ring pliers that can open up wide, most snap ring pliers i've been using on this job suck..makes me despise snap rings
