Nothing is coming out of the vents at all

I push down on the pedal and it doesnt sink to the floor and I slow down, however I am still putting a lot of pressure on the pedal and slowly the brakes let go anyway. My emergency brake is what stopped me. Im not low on fluid and I dont think I am losing any. Will bleeding my brakes do me any good or do I need to brake down and get a master cylinder? Or is it something else entirely? I just want to solve the problem having brakes go out is not something I want to do again.

my car has been turning off while drivng. does it on the high way doing 70 . it will cut off for a split second then kick back on . enough to be afraid. camshaft positioner sensor has been changed brand new an it did not fix the problem. it only does at high speeds.

Have replaced crank sensor, harmonic balancer, MAF sensor, 02 sensor, fuel regulator, and tested IAC and MAP sensors. Fuel pressures are all good. New fuel filter, air cleaner and spark plugs as well. Removed entire throttle body and completely cleaned it too. Car starts and runs great....just shuts off 2-3 times a day and immediately starts back up. Only code I can get on my scan tool is P0629, which is "invalid pass key frequency"?

I have all the nuts loose except the one that is on the bottom closest to the firewall. That nut is on a threaded post that is turning with the bolt. The post goes into the plastic piece that the TB is attached to. I was so close to getting my TPS on. To get stuck on this is frustrating. It says nothing about this in the Haynes manual or anywhere else that I have looked.

My air condishoner only blows hot air now what can this problem be ?

drove my car yesterday it was fine then i came home for a few hours and then went to leave again and it would not start. i have had the fuel pump, the crankshaft position sensor, and the camshaft position sensor changed and it still does it.
