rough idle, climate control not working, brake pedal hard

I just replaced the windshield wiper motor on a 92 tbird 3.8L. Now the car idles roughly, I can no longer change where the air blows out of inside the car and pressing the brake pedal feels harder. The manual climate control is on defrost and I can't change it to anything else. When I push the button for vent or ac or max ac, etc. it only blows air out of the defroster vents. The car idles roughly and sometimes dies. Lastly, the brake pedal feels harder when pushing the brakes.

So where do I start?

Thanks for any and all help.

Check for a vacuum line that is disconnected.

Ah crap, that's what's wrong with mine... Shoulda known, but oh well, it's back to the garage for me.

That was it. The first look I took under the hood I didn't find it. I went and looked again and sure enough there were three small hoses disconnected from a "tree" near the middle of the firewall. Fixed all of the problems.

Now I have a brakeline leak. I guess I'm going to the garage as well.

Thanks for the help.
