my daughters 2019 tucson A/C is dead. i checked for pressure in the lines and none is to be had. So its probably got a leak somewhere. I could take it to a shop and pay the amn , but i was thinking of just getting a complete kit like this and changing it all .

car has 108 k on it and got a new engine last year . i have charged systems before so that won't be an issue

What do you think ? take it in or jsut replace everything ?

If you have the skill, I would say go ahead and use it. That kind of work is expensive if you take it in. Both parts and labor will be very high. Especially at dealerships.

Also, now that the weather is getting warm, they'll be inundated with this type of work, and most likely will be quoting these type of jobs high. If you can do it, I would.
 
If you have a vacuum pump and the specs, it isn't hard. Worst part is probably replacing the condenser. Well, getting the old one out and then putting everything back.
 
i checked the compressor and it s not locked up so i think its good. i would take it to a shop to have it charged . i live i wa state and no more cans for us to self charge . even after paying for the charge i estimate i would be around $650 in
 
There are Indy shops that know what they are doing and not as pricey as a dealer.

There will be oily residue around a leaking valve or fitting.

If not a leaking fitting or valve then probably a condenser since the position it's in is the most likely.

You can fix it and just have a shop pull a vacuum and check for leaks then refill by weight.

You need to find the leak, it might just be an o-ring. Why fire the parts cannon at it?

^^^^As a BITOG member, you know this is the only correct response. No need to shotgun a potentially expensive solution without first pinpointing what is likely a minor leak. If you throw multiple parts at it, you might actually create an additional leak(s) in the system and exacerbate the problem.
 
I did a complete AC system on my daughters 2008 Sonata last summer using RA parts and it's colder than ever. The kit you show doesn't include a condenser which I would change while your at it.

PS: I don't know your daughters maintenance schedule (oil changes especially) but it doesn't say much for Hyundai that it needed a new engine in only 6 years (and presumably under 100K at the time) and a new AC in 7 years. I owned 3 Hyundai's before their engine issues but I wouldn't buy one now.

I agree, but, have to say that my sons 2014 Kia Rio is going on 13 years old and AC still blows cold (knock on wood...) Pretty amazing actually.
 
i looked around pretty good and did not see any oily spots . i could not see the condenser except the front trough the bumper unless i remove it .

I can't buy cans for testing in WA state and this thing uses R1234yf . The system is empty . i may try the air test to see if i can find the leak . how long its been empty not sure . could have been a slow leak over the winter . its only gotten over 70 these last few days .

The kit I linked has condenser etc. there is plenty of space underneath and top to do the work . I would not be surprised if the condenser got a rock strike and put a hole in it . the net say just the condenser replacement will cost $1000 .

on the engine replacement. even though i change oil every 5k with oem filter, at 90k it started drinking oil. Hyundai dealer did a test and Hyundai give us a new engine under warranty . People rag on Hyundai, but this thing other than the oil consumption has been as reliable as my Hondas.
 
Is it a Tucson or a Tucson XL? Reason I ask is, sometimes the unions behind the dash fail. Had this happen on a friends vehicle. Ended up costing them $3k.

I have that in my Jeep. I often wonder if you have one side on HIGH, and the other side on LOW, if you could get both the heat and the A/C going at the same time?

should be . there are seperate blend motors for each side
 
What if it's the evaporator?

Was the factory fill of refrigerant dyed?

I don't like the shotgun approach. Find the problem and fix that.

We had a 2008 Elantra that was an excellent vehicle. The Elantra started going downhill after the 2010 MY and I think that's when they went to a different 2.0 engine. The 2.4 engine was problematic in most H/K vehicles.
It's not just Hyundia/Kia....it seems Mazda, Toyota, Honda etc...are having their share of issues too....part of the problem IMO is too much (unnecessary) technology and they let the customer be the guinea pig testing it.
