No start issue and blowing hvac fuse

Just looking for some extra input on a few issues. 2014 Pete 386 VIN# 199593
1) no start issue happens quite often now. Turn the key to only a single click. I might have to try 5 or more times before it finally turns over. The batteries are fairly new and still holding a charge. The connections are tight and non corroded.
I think it could be between the starter or the ignition switch. I am leaning more toward the ignition switch. Any thoughts?

2) About 2 months ago I went to change my hvac from vent to defrost and it wouldn't change. I of course checked the fuse and it was blown. Changed it and tried to change to defrost again and again blown. Another fuse put in and this time I tried to go from hot to cold and you guessed it blown fuse. The blower works fine. I can go from off to full blast no problem. I changed the blend door actuator and I did not blow a fuse for 2 whole days then I went to switch it up again and blew the fuse. I now have it set on defrost and warm which is fine for now until it warms up. I was possibly thinking bad hvac console.
Any input/ideas would be greatly appreciated and I thank you all in advance.

 

Thanks for the feedback. However, my blower works fine in all positions no issue with the blower at all. The fuse blows when switching from vent to defrost or similar and also blows when going from hot to cold.
