Hi every one. I just spent 240$ at a garage to finally tell me that the rear line is leaking. It is leaking at halfway. I saw the dye. Now, my options are:
1- replace the line
2- cap off the line and only have front A/C. According to a shop, they do that all the time as the rear A/C always have these issues as the lines are not very well protected.
Now, here's what I want to do. I am going to get the rear A/C line capped off as I do not live in the South and the rear can do without A/C. The shop is charging $400 to simply cap 2 lines. It seems really overpriced. I want to remove the lines myself, and get them capped off at a proper shop. It will save me at least $200.
Is there someone who has done the capping off of the rear A/C line and also have pictures and any kinds of a DIY list. A diagram of the full 2006 Envoy XL A/C set-up would also be awesome.
I know this is not the best solution, but I am getting rid of the vehicle in September and I dont want to sink a $1000 in repairs. As long as I have front A/C, I will be happy and most importantly, the wife will be happy.
Do you have the proper orange Dexcool engine coolant or the old regular green stuff? If green,then I suspect it's the rear heater core that's leaking (same as mine). Mine was leaking through the A/C condensation water drip nipple. If it's just a little coming from the actual A/C line, then it could be the fluorescent dye that is usually added to A/C systems to help find leaks. If you have an ultraviolet light, this would confirm it. You can buy an ultraviolet bulb and use it in a regular worklight.
Definately A/C, Fluorescent green. Plus the AC is starting to go. With 97K miles and possibly a trade in a year or so, I am thinking of capping and recharging, using Front only. I ran front only on a recent trip thinking that may conserve my Freon since I knew I had a leak (probably didn't)
Talked to these guys and the job looks fairly simple as a DIY. I have a guy that is a HVAC guy and does his own recharge on his and family vehicles, so thinking of going that route. Any comments on this kit?
Didn't even know such a kit existed. I can't see why it wouldn't work. A lot easier and cheaper than getting an A/C shop to close it off for you with aluminum welding. Gotta love eBay! :thumbsup:
Ok I blocked the rear lines. (Kit was $75 on Ebay) After pulling a vacuum for an hour on the system, and checked to make sure it held a vacuum, I recharged with 1.9pounds (approx) of R134. My only concern is that I obviously lost some PAG oil when the rear line leaked. Not sure how much. I have a bottle of PAG 150 however have no idea how to get it into the system. First, do I need to put more in? If so how do I get into a charged system? I did not replace the condensor or compressor, I would assume there is still plenty of oil in those.
BTW have run the air and seems to be working great.
Unless you have an oil injector for A/C systems, there's no way for you to add oil except using a DIY can of R134 with oil in it. I don't think it would need a full oil charge but I would add an ounce just to be on the safe side. Don't forget that there was likely some oil in the lines you just blocked off plus whatever was lost in the leak. In your case, the best would have been to add that ounce in the accumulator before filling it. The total system capacity for oil is supposed to be 8oz.
So it's your call if you want to try and add some oil with a can or just leave it and hope there's enough oil to keep it from self destructing.
I had my A/c recharged last summer. It lasted about 3 weeks and quit cooling again. We don't drive it much in the summer so I left it until last week. Mechanic couldn't find any sign of the leak so he had to fill it again and wait for it to leak. That sucked, my bad, had to pay $140 just to charge and find the leak.
We are driving it more often this spring and will take it back in a week or so so he can find the leak.
My question, which I know is jumping the gun. Do you get 4 of the block units in the ebay kit? One for each end of the high and low pressure lines? I am just coming up with my options.
I have a 2004 XUV (XL) that has a freon leak that I have been unable to locate, so this thread has me thinking that it is in the rear AC system (didn't realize I had a rear AC unit...). I will gladly give up the rear AC functionality to get the dash AC working, (and will disclose such to any subsequent buyer..). Does anyone have experience using the AC Blocking Kit, from A+ Auto Cooling Solutions, (EBay store), which is used to block the AC lines going to the rear system? I am interested in knowing how difficult they were to install, did they leak, etc.? Thanks!
I had the same problem with the rear a/c line rubbing the frame. I bought some j&b weld and patched the hole myself. I didnt have to disharge the system to do this. I added 2 cans of freon and everything works fine.
