Why does the ac start cold but when you turn the car off and restart it it blows hot air?

In most auto ac units, the ac compressor is "at rest" below about 1500 rpms. You usually don't notice it at idle during normal driving because you are stopped at fairly quick intervals. Once the engine has stopped, the inside temp has risen noticeably and you feel the circulated warm air before the compressor kicks back in. The compressor is also designed to cut out over about 4000 rpms. A sensor picks up on the heavier load of the engine and disengages the compressor to supply the extra power needed.

1998 intrigue with ac driver side blows hot and passenger side blows cold?
My 1998 Intrigue did the same thing after battery was replaced. Found the answer online. Turn the AC and car off, disconnect the battery, wait 5 minutes, open both front doors, reconnect the battery, start car, turn on the AC full cold. This resets the computer and the AC works perfectly!

Cold boot, also called a hard boot, is starting your computer from a completely shut down state. You turn the machine on when it has no electricity running. Warm boot, or a soft boot, is nothing more that using the restart function - you don't shut the power off, you use the software to restart so the operating system.
