My a/c has started blowing out of all the vents (defrost, front, lower) when set to just the front. It isn't blowing very cold either.
It seems to blow out of the defrost vents the most no matter what setting it's on and very forcefully when turned up.
Only when I set the a/c temp to "low" does it blow cold and out of the proper vent.

I recently relocated the a/c to the lower compartment but I don't see what I could have done wrong there, the connectors seem to be pretty idiot proof when it comes to hooking them up.

Ideas and suggestions would be appreciated!

 

I can't help with why your re-installation has caused the problem, as it's difficult for anyone to diagnose a change without seeing it, but that is the exact reason I never rewire or change anything electronic on modern cars. Everything is just too integrated to fool with any of it. Good luck.
