Well, recently as temps here in Texas approach 100 deg, I am starting to have a problem. My air blows cold when I am driving, but when I stop, it doesn't. Now, when I hit the brakes, I hear a ppppppsssss from the passenger side. It sounds like a vacuum line. It only does this when the AC is in the MAX position. I spoke with 2 people, and one suggested the alternator might not have enough juice to keep the compressor on while at a stop, and the other suggested the mode switch might be bad. Can a bad mode switch cause the system not to cool? Any ideas would be appreciated, thanks!
