So my ac started blowing hot air. After a day of this, it just started blowing cold AC again without any work. That lasted about a week. Now, it's been hot air for 2 weeks.

So I got a recharge 134a kit, and followed instructions. The pressure gauge went to just over 100, in the red zone, and the instructions said not to recharge it at all. So I didn't. It stated there's some other problem and I need to take it to a professional.

So any ideas what else it could be? Any tests I can run? Is it the compressor or do I need to take it to a mechanic to test it?

I have a 2004 4.0 V6 2x4 explorer.
