Not sure which the TX valve is. But the expansion valve, which I think is the thing which can fail more often than other bits, is located under the dash, connected to the evaporator. It's not that hard a job to get to it, just a bit fiddly, and of course the gas has to be taken out first. But the other valve which may be the TX valve is located in the engine bay behind the compressor, on the chassis. This would be easier to replace than the expansion valve, but would be a more expensive item I think.

I think Seamus is right there, it's behind the glovebox, Sorry Mel i don't have a picture for you.
I too am a little confused with the tx/expansion valve so hopefully some more helpful posts will follow.
I did find these comments from Troy in an earlier 2005 post that may help.
"TX Valve. This valve switches the compressor on and off to regulate temperature. TX valves have a few different ways of dying. Dying on will make the air con extremely cold, as it will never shut off the air conditioner to maintain a temperature. Dying off will cause the compressor to not start up, and will just spin on the clutch as if the air con was not turned on. TX Valves can also start to turn on and off too rapidly, resulting in the air conditioner not cooling well enough. To check this, turn on your air conditioner, and with the doors closed and your windows up, time how long it takes for your compressor to turn on after it has hit it's correct temperature and turned off, then time how long it takes to turn back off again. Then, with an accurate (Usually digital) thermometer, place the pickup of the thermometer in your centre air vent and read at what temperatures it turns on, and at what temperature it runs off. If they are close together, but your air conditioner is not cooling the cabin, but the temp of the air coming out of the vent is cold, then that will be your problem.

that seems to be what is happining Andreas, was checked out, the air con is blowing cold, just not at correct temp, the air con guy has never worked on a soarer, he did say it was the tx valve, he said it was behind dash, he also said it was possibly a big job, he was thinking he would have to remove dash, hence reason i am looking for advice, where situated etc, am willing to pay, thats not the problem, anybody want cash job to fix it, i can get the parts and get it regassed, just mail me direct
