So i just got a used 07 chevy crew cab ltz 4x4 and i got a few questions.......

1) Auto door locks seem not to work when in park or out of park....i have gone into the menu and made sure they are on and nothing....

2) On my climate contol for the pass side seems to have had some sugary drink spilled on it and now all the buttons stick...I have sprayed them out with electrical spray but it didn't seem to work..(maybe i should keep doing it everyday)

 

I looked through your owners manual. The information for settings are on pages 291 through page 301. This should have all the information you need but if it still not working I would suggest you take it to your dealership to have it looked at (and while the vehicle is there tell them about your button issue on the passenger side). I hope this helps!
