I have a 2007 Honda Pilot and recently the air conditioner (A/C) began switching between cold and warm, even when the controls are set to full cold. When driving for a few minutes, it turns to warm. When I get to a stoplight it gets cold again. It remains cold when idling, until I accelerate, at which time it gets warm within a few minutes. I have recharged it with a full (20 oz.) bottle of "AC Pro". When recharging, the gauge indicated that it was low, and I brought it back up to the green. I've read plenty about whether the "do it yourself" kits are worth it. All that debate aside, the issue is no different than before I recharged it. Any suggestions would be appreciated.
