Steam coming from vents

SOURCE: air not coming out of vents

what your problem is that you have a issue with the vacume system, what i did was removed the bottom panel on the passenger side looked up and you will see a bunch of wires, look for a black box (should be right above your head by time you squeeze in there and it has a yellow/amberish type of color you will see that you can remove this its a rubber piece cut the pink tube on the side about 2 inches away from the plug assembly, and slide it into the blue tube this will bypass all controlls and shoot the air out of the front vents, you WILL NOT beable to set it to defrost max/normal or htr (mainly which vent flaps are where) this has worked formonths and the a/c acts as if its on normal mode to use the heat just slide the switch :) until you can test all the other equip this will keep you cool or warm

99% chance it is the blower resister located behind glove box. Squeeze glove box in and pull out.
The resistor is right behind it, dealer part cost less then $20.
Dodge has had this problem for over ten years and until recently did nothing. Now they combine fuse with resistor, suppose that will correct it?

• Assumed your AC unit is OK, but uneven temperature distribution. Try to throw the heater on an off severtime. A sticky valve on the heater would cause similar problem.
  
• Observe the RPM while parking your car. While the AC cut in cut out (or turn on an off). If it cause no load on the engine. The freon may be low or the compressor is bad. In this case only the intake side of the evaporator is cooler than the other side.
