Many thanks for all the help in the past.
Current problem, the outside temperature gauge showed -36 degrees? and
this I think caused the A/C not to work.

This problem occurred once before( apprx 1 month ago), and after sitting overnight, the gauge went back to normal, and the A/C worked fine.

I had it tested , and no error codes could be found.
Now just yesterday had the same symptoms -36 degrees and warm air coming from vents?

Any ideas, thoughts?

Thanks,

Mellobenz

If you can identified the temp sensor is not working, replace it. It should not be too expensive. Bad temp sensor will not set a code as long as it can send a temp reading, even that reading is incorrect. You can pull out the sensor and use dielectric fluid to clean the connections may help. Poor contacts may cause bad readings.

Not only will a bad outside temp sensor effect the air conditioning, but also how your engine runs. As the sensors get old they start to get inaccurate with their readings. If your outside temp sensor is 10-20 degrees off, when you change it you'll defiantly see a difference in how your engine runs. Especially on boosted cars (s600 s55 s65). The ME computer watches the outside temp sensor...
