Question Blower on Defrost only and Cruise on Fritz

2003 Ruby. Pulled the fuse panel off to the side to change my battery yesterday.

All of a sudden today no matter what I set my ac/heater to, it's only blowing out the defrost vents.

Also, my cruise control won't set a speed and stay on it.

Could I have damaged anything while changing the battery? Blew a specific fuse?

It's been raining non-stop here in the NYC area and my vehicle's constantly outside so I don't know if it could've been water damaged or over humidified?

Any help appreciated!

Thanks! I could've accidentally pulled the line and it affected both?

Yes you could of. The cruise is operated by electronics and vacuum. Also "Defrost" is the default setting for any vacuum leaks.

In the second post I made the vacuum line pictured is under the battery. If not there follow the vacuum lines until you fine the one that came unplugged. If you do not know where it goes just post a photo of it and we will let you know.
