Climate control Issues

[Tbilisi79]

For some reason, when in Auto mode, it will start blowing hot air out of nowhere at full blast. Sometimes from the left side, and some times from the right. 15 minutes later its fine.

What can I do to fix it?

Thanks

I have run the diagnostics and they helped a lot. Its worth reading through the site if you have not yet done so.
