So the other day I was installing a new car stereo in the car as I wanted to 

change all the stock speakers as well as add some bluetooth functionality to 
the car. After installing all of the door speakers, I installed some tweeters into 
the stock location (in the dash). I had to shove them up into the location as did 
not want to remove the whole dash. Now heres the issue... After installing 
everything correctly, my climate control will not work at all! The only thing that 
works is adjusting the blower! I cant turn on the A/C,change where it comes 
out, or turn on the defrost! When I Push the button none of the lights come on 
only the illumination lights come on at night! this all started happening after I 
installed the tweeters as I had the stereo in for awhile before this happened. So 
I'm wondering if I bumped/broke a cable or something. I also should mention 
that my tire pressure light is on even though all my tires are filled correctly and 
my cruise control turns on but I am unable to set it! Any help would be nice!

Start with what year and model you have.  Seems to me you unplugged or... broke something when shoving the tweeters into place. Only answer is take it back apart and hope it is just unplugged.

are you absolutely positive it started immediately after installing the speakers? 

 

tire pressure light - that implies something newer like 2005+?  year and model please?

 

a wiring harness was disconnected - just go back in where you work and look for something disconnected. 

FSM's will have intricate detail but with all that detail are hard to sift through too if you're not familiar.

 

check fuses - though i doubt that's your issue here.

I just wanted to thank you for the fast response! anyways its a subaru legacy 2012! and I forgot to include this but i have dissembled the car and it seems as if everything is plugged in. I probably spent an hour just looking for an unplugged cable/ broken one but i just cant seem to find one! and i also forgot to mention that i did go through and look at every fuse in the car and by the engine and all were fine!

Its a Legacy 2012 and i checked all the fuses and all seems fine (both by the engine and on the drivers side!) I probably spent an hour just looking for an unplugged cable/ broken one but i just cant seem to find one! any help would be nice!

just checking but did you pull the fuses and test or just visual inspection... I have been fooled in the past.

i pulled each one did a visual inspection... I'm going to do the same but test them as well!
