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)

Step 2: Dash Cover Removal
This 2004 Chevrolet Silverado came in with multiple hvac actuator faults. After diagnosing a faulty passenger side blend air door actuator with a Tech 2 scan tool it was time to remove the dash cover. Not a big deal but there are a lot of steps.
Lift the lower edge of the dash end caps and remove the covers.
