This is an 06 TB. The A/C blows cold for about 30 minutes and then you get warm air. This is an intermittent problem but does occur frequently. What could be causing this? Could the A/C somehow be freezing up?

Mine does that too! Going along all of a sudden a blast of hot, then back to cold? It seems to work "Ok" but that?
