Temperature Unit Problems? Help?

Hey guys thanks for checking out the thread, I really appreciate it. I'm having a problem with my temperature control unit below my radio. And keep in mind, some of this doesn't ALWAYS happen but it does happen.

1. The defrost setting doesn't do anything, all the blowers turn off. I know that the defrost thing could possibly work though because for a short moment after I switch the setting to feet and head blowers the defrost fan will also come on for a couple seconds.

2. The entire unit will just not work sometimes. As in I'll turn it to the any configuration of settings and nothing will happen.

3. When the unit is working all the speeds will work just fine, its just sometimes it doesn't work and sometimes some of the settings don't work as to where the heat goes. Mainly the defrost.

4.Normally in the early morning it'll work when I go to start my car for the morning, but usually when I come out to the parking lot after school it won't... Hmm. Any help would be totally appreciated!

Pull that switch and inspect the back for possibly corrosion or melting on the connections. Also look up behind the dash and inspect the vacuum actuators while you are changing the settings to defrost. The middle of those 3 actuators control the defrost.
