AC/Heat Question
 

The AC will blow real cold when it is set to MAX A/C - On any other setting, including AC it blows warm no matter which position the temperature control dial is set.


My guess is low refrigerant in the AC. A few questions:

1. If you don't think it is low refrigerant what do you think the cause may be?

2. Is there an easy way to check the refrigerant level?

3. Has anybody used the kits to recharge the system and if so what brand have you had good luck with?

Thanks in advance for all replies.
