The A/C does not work on my '94 Tourmaster 8391. The fan blows warm air with the A/C set to the coldest setting. Had it checked, pressure was good, but it was low on freon.

This raises a few questions:

1. Where did the freon go?
2. Is it R134 or older impossible stuff to get?
3. How much does it hold?

A mechanic looked at it and said it was the orifice valve. Not a part that is readily available and it is not a DIY. That would require the system to be flushed and oil/freon added after changing the orifice valve. Has anyone heard of the A/C not working due to the orifice valve? If so, where can I get one? A search online is not great!

I know it is getting near the end of the season, however, freon is also needed for the defroster so I will need that in the coming months.

Thank you!
