At 90,000 miles the heat began to not blow when selected 1, 2, or 3. The system only blew air on position 4. This turned out to be the blower resister. Then a few months later, the AC would not blow cold. A month later the AC worked again but only blew through the defrost. Here are the symptoms: 1. hot or cold only blow through the defrost (top dash vent) 2. hot began to blow cold only as fan sounded like is was on very high speed. 3. selector switches climate control would not move air from hot to cold or dash to floor. 4. Put heat on high defrost and held down all 4 power window controls. This slowed the motor down and heat would blow out the defrost. 5. At times you could select mid vent air with the car off. When the car was started, air would actually blow out the mid vents then after 10 to 15 seconds go back to the defrost vent only. 6. Finally; when using the window trick to create hot air , the fuse under the hood began to blow out. This left no window control. Odd as this fuse is not labled for heat/ac. So this 20 Amp fuse would blow and there was no blower motor, no windo control, no indash readout for temp, mileage, and no cig lighter. Very odd all these systems tied to one fuse. Car goes to the shop: 1. Replaced timing belt 2. Replaced water pump 3. Replaced heater core 4. Of course all new fluids These are routine items as per the cars mileage but did not go to solving the heat problem. I will save you my rant of 3 Dodge dealerships, and 4 independant shops and simply say that after another $2,000 the heat/ac still didn't work. A letter and phone call to dodge coroporate yeilded a quick "buy a new car". Then shops began quoting prices for more work that involved "taking the dash apart" The last quote was $950 for a new BCM (body control module). Stated that the part is $600 and involved taking the dash apart. Lots of work they said. Some conclusions and fixes: I decided to do some work myself. I have not worked on cars in 15 years but used to build hot rods. No stranger to tools. I purchased a used BCM for $135 next day ship online. It took me 15 minutes to remove the portion of the dash where the BCM is located. It is attached to the fuse panel under the dash. I installed the new BCM and put it all back together in 15 minutes. (Of course battery disconnected at all times for this procedure). And to my amazement, everything worked. For a time anyway. Oddly enough, the controls didn't hold up. Now I am not blowing fuses. I can get hot or cold air. I just can not control which vents the air will blow out of or whether the air will be hot or cold. I can turn the car off select cold and get when started get cold air. I can turn it off, select hot and get hot air. This is not 100%. Sometimes when I restart the car, it just stays where it was when it was turned off. i.e. hot when turned off, select cold, turn on, still get hot air. At this point I am ordering a new climate control switch setup for the dash. My assumption is that this part for controlling air is the last piece. I will keep you posted and will respond to anyone what wishes to go down this road as a DIY project to fix. Invest in yourself as I have already bought this car twice at this point just trying to get some HVAC control. Hope this helps someone.

Ok, we installed another dash climate control unit. The piece that works the temperature, and selects fan speed, etc; above the radio. No go for working. We now have a AC/heat system that still just blows out the defrost area. And sometimes switches to the mid vents or floor vents.
Another update: I have found the mode and blend door acutators. I have folllowed the instructions to "recalibrate" electronic door controls. They are two separate parts. One is located right by the gas pedal. I am not sure how to remove the unit as it has small screws that you have to get vertical to remove. I am not sure how to test the unit to make sure it works or doesn't work. Two Dodge people have sent me diagrams and suggested that I swap the two parts and see if one works. Both diagrams are incorrect as they show the piece that operates the door for the Max AC setting. This car only has one of those actuators. So we are still in the dark at this point. Does anyone else have suggestions?
I have a 2002 Dodge Stratus SE with the same problem. When I turn on the AC or the heater it goes to the defrost vent on top. I can sometimes make it go to the front (towards the face) by setting it to the defrost setting and slowly turn the **** to the left to change it to the AC, or by wiggling the **** a bit. I took the climate control out to see if the cables were loose or damaged, they were fine but I noticed one wasn't plugged in at anything, and I dont see a place to plug it into so im wondering what thats for. I have to buy a new climate control box thing because I broke it off of the plastic dash thing. Let me know how it goes with your problem.
I kinda have the same issue, but its not happening all the time. The problem that I seem to have is when driving I notice that my feet get a little cold. I have the control set to floor and defrost. I put my hand by the defroster and the air is cold, but the control is set pretty warm. If I move the temp to hot it will get hot, so I know its not the blend door. I can see that door with the Radio out too. I then turn up the air but notice I am not really getting any volume out of the vents. Even if I move the level to the air vents towards the face it will switch, but very low. The blower however is blowing hard and i can tell that it is being blocked by something. Not sure what since after I shut the car off. 15 minutes later it works fine. I have reset with the IOD fuse, but still does it.
Ok so I have kinda the same problem, but I didn't have any problems with heat or cold air. The only problem I had was that the fan would work on #1, the lowest setting, but would sometimes make a grinding sound and would not blow any air out. On monday I had the fan set on #2 and it made the grinding sound, which it never did on any other setting but #1, and then it wouldn't blow any air out on #1 and #2 and only on #3 and #4. So took it in to see what the problem was and it turns out that the resistor and blower motor went out and recric door actuator went out. So we replaced all three for a cost of $500 and as of right now everything works ok.
Climate control did not fix problem. Noticed the problem on defrost today to. Car running about an hour before it happened. I am wondering if the heat is causing the mode door to get stuck in a funky postion. I can hear the fan blowing and you can hear the difference. Its like its blowing into itself. You can change modes, but you just dont get the air volume. After the car sits off for about 15 minutes it fine. I had the car apart and tried to get it do it while I was measuring the voltage at the head, BCM and mode motor, but could not get it to do it for 1.5 hours. Hopefully it will happen on my way to work where I can check it not being in the cold. This is supposed to be the winter car for me. No defrost no can drive.
I've been fighting a similar problem where air blows out of different vents at random, even when hitting a bump in road.
I noticed the lights flickering on the dash climate control unit. The (6) pin white connector on back repeated the problem when I moved it - lights came on/off and air blew out different vents.
The whole dash climate assembly is a Lucas part 58024. I cleaned the connecting pins but also took unit apart (with 3 phillip screws) and found (2) of the (6) pins had cracked solder joint on the printed circuit board. Added a little more solder and the unit works fine.
Thought I'd share in case it might be a problem on other units. About drove me crazy since it was intermittent.
This is just something that worked for may and I wanted to put it out here in case it may help someone else. I have a 04 Stratus and I lost control of hot and cold and it would only blow out the defrost vent. I ended up taking out the control unit in the dash and resoldered the connector to the circuit board. It seems all the joints were bad. After doing this mine has been working correctly for about a month now. So far so good. Hope it may help someone. I guess this has been updated since the last time I looked looks like someone else already posted the same fix but that worked for me too.
I had similar problems with heat not working and cold air blowing out of the defrost instead. It might be unrelated, but this happened shortly after my stereo was stolen out of my car.....forceably. Because of the theft my center console frame was broken in multiple places but would still snap in place. At any rate when I started having the problems I also noticed that all the lights for the center dash stopped working as well(led for heat controls, etc.). That got me to looking at the connections and I focused in on one connection that went into the back of the climate control unit. At fist all I had to do was pull the unit out and put it back in and then the heat would start working. But eventually it seemed that the wire itself was having issues at the connector and I had to literally lift up on the connector and then the heat would consistently work. There is a gap between the connector housing and the climate control unit so I jammed a quarter in that gap and it effectivlely forced the connector up just enough to keep things working permamently :-). I suspect it is bad solder joints as was mentioned above, but me and solder irons are like oil and water so this works for me for now.
