This instructable is how to remove both driverside and passenager side temp controll actuators in a 04 Chevy Siverado. If you have noticed that your temp controll units are on cold and it is blowing out hot air then there is a good chance that the actuators that controll what type of air (hot or cold, or both for dual climate zone units like this one) are going bad. a first simple fix for this is to set both temp controll dials to COLD, then disconnect your battery for 5 mins, reconnect and DO NOT TOUCH THE temo controll buttons, just turn on your fan to max and your AC button, DO NOT TOUCH THE TEMP CONTROLL BUTTONS FOR AT LEAST 5 MINS!! if it is blowing out cold air after that  CONGRATS!!! problem solved!!! IF you contiune to get hot air when it is set to cold then READ this insturactable and save a few gran from the dealer. (I really mean a few grand.... this takes ALOT OF TIME AND WORK SO BE WARNED)

NOTE:  I FOUND THIS INFO FROM ANOTHER WEBSITE, BUT THE PERSON THAT POSTED IT WAS CONTACTED BY ( CHEVY OR SOME COMPANY I GUESS) AND WAS TOLD TO STOP POSTING ON THIS. SO OUT OF NOT WANTING TO GET THAT PEROSN IN MORE TROUBLE I (SORRY GUYS) WILL NOT POST THE WEBSITE HERE.

there is a lot of things to check, start with the fuses, if you have a powerprobe, see if the actuators and the blower are working, make sure that all of the harnesses are plugged in tightly and that there is no corrosion on them, hit them with some spray contact cleaner to make sure, also check anything else electrical that you had to disconnect to make sure that it is plugged in. there was also a recall on a particular harness that plugged in on the passenger side of the truck beneath the glove box that dealt with this, you might want to check that as well with a tester. there is a lot of things to check on this particular issue.
