Default AC is now stuck on??

I have finally fixed my leaking weatherstripping.
Yet im having all sorts of issues all of a sudden, the carpet has been out for 2 days and the car is bone dry. BCM was taken apart, was clean and dry and doesnt apear to have ever been wet.
Problems Im having in order:
1. HVAC lights stay on at all times.. I pulled fuse #27
2. Keyless entry no longer works, even with fuse #27 in.
3. Whenever HVAC is turned on in any mode the AC is on. I visually inspected and seen the AC clutch is indeed engaging. I had the heater on this morning and the AC was also on. I shut the heater off and the AC clicks off under the hood???

As the climate dries out you think this stuff will heal itself over time?

This is the stuff ive done to it.
1. Cleaned all the drains out.
2. Took apart a some of the grounds, cleaned them and put coppershield anti corrosion stuff on them.

Think I just have to wait it out? Or is something F'd?

Just a thought. Rain water can dry leaving conductive deposits. If the BCM did get some rain it this could be the problem. If you exhaust all other avenues try scrubbing the cards with a tooth brush with a mild solvent.

I did use electrical contact point cleaner and sprayed it all down.

Sounds like you covered it but I'll ask for your sake...windshield defrosters are shut off, right? A/C stays on in this mode.

I have often thought my AC was stuck on, only to realize that I had the front window defrost is turned on (which turns on the AC). so you may want to check that.

If i have everything off, then Turn vent to "floor", defrost off, temp all the way hot, I turn the on to "1" and I can hear the AC clutch click under the hood and prior to today the AC light would still come on. Now the light goes off but im sure the AC is still kicking on. I also used to be able to switch from outside air to inside, now the button does nothing.
Probably more stuff still wet.
Im just going to get my other car together and get it out of my garage and put this one in there, its been monsoon season here in Wisconsin lately.
