I checked the TSB thread and I could not find any information on this particular TSB. Does anybody have any info on it.

I found the link on that other HHR site. but it is a members only link. :(

I have it.....what do you need to know, specifically?

Generally it says that certain suppliers have contaminated R 134 freons. The contamination can lead to reduced effectiveness and premature component failure. The industry has no established standards, although THEY are working on them. GM has its own standards and suggests repairs, be done by a GM dealers to assure correct performance and longevity of the systems.


Side note......years ago, I was responsible for purchasing this commodity for GM. The best companies, names that you would recognize, had contamination problems. Through the years and through continued technological development, the need for much "cleaner" freons was needed.....kind of like "quadruple filtered". What was allowable, and manageable, in contaminants 8-10 years ago, is a problem now.

Unfortuneately, the retrievel source I use for TSB's is not printable, downloadable, and can not be copied......or I would gladly post the info.

The reason I ask is my A/C is not getting cold enough. I took it to the dealer and had them check it out. They said that it was charged correctly and suggested that I set it to recirculate but even that didn't allow it to get cold enough. I want it to get cold enough that I need to turn it down, and on an 85 degree day that shouldn't be a problem. I have another appointment set for Friday. I will probably tell them to evacuate and recharge the system.

A quick check for you.....

You need to have a temperature probe.

Start the car and turn the a/c to the coldest setting, fan on high, recirculate. Make sure the car can pull air into the front freely...not in a garage, against/near a wall, etc.

Put the temp probe in one of the upper middle dash outlets....generally the drivers.

Read the coldest temperature, it may take a minute or two (there is a spec. on this, but I can't remember).

Generally, 60 degrees and under is excellent in a 90 degree ambient. If it's 70 or above, you have a problem (aas the ambient rises, so does the output).

I, personally, do not accept anything above 60. In Arizona COLD a/c is a must.;) :cool:

I will try that. I know it wasn't cold enough because I had it cranked all the way and my wife was still comfortable. Usually she needs a blanket when I am controlling the A/C :D
