Intermittent Glitches (AC, Locks, Windows)

I seem to have developed a case of gremlins in my 1996 98. It has a host of glitches. When starting the car (Especially on hot days), it takes ~20min for the AC to stop pumping air through the defrost and side vents and divert it to the dash vents no matter what setting the AC is on. Is it normal for it to take so long to switch over? Also during the hotter days of summer, the keyless entry/power locks/windows seem to stop functioning properly. Sometimes the remote won't do anything and other times the horn will honk like it has locked the car but the doors don't actually lock until I manually use the lock slider. The interior power lock/window button has no effect either when its acting like this. I can manually raise and lower the windows with the individual switches but the driver's master window panel is dead. Any ideas? Thanks!

Check your main ground cable for corrosion and clean it if necessary and put some dieelectric grease on it. Could cause electrical glitches.

A bad Body Control Module comes to mind....
