After i installed my after market stereo in the lower cubby, my climate control has gone under.

Air blows but seems to only blow the outside air and doesn't change temperature.

Also when selecting where the air blows (Feet, Head, Defrosters, ect..) it stays where i had it before the installation of the radio. I've been told i could have not reconnected a vacuum tube. Any ideas?

2004 without dual zone or navigation.
