Question about 2004 Dodge Ram 1500
You should probably just let him drive,unless its a manual transmission,he should only need his right foot,the ac is obviously working,the problem sounds like damper controll malfunction,the venting system works on vacuum generated from the engine,when you switch to defrost,it opens the proper vaccum line to move the damper or diverter in the main ductwork to divert the air to the defrost,same thing for all the other settings.,as long as the open close controls that you can reach on the dash for the individual vents are working properly,should be able to see the vent louvers open and close ,if they are ok ,the most common problem that i see is a pen dropped down the defrost vent,jams the air diverter and it, stuck half way beetween two positions a small inspection mirror may allow you to see down the defrost vent,the other problem is that one of the vaccumm lines may have come loose,toggle through all the settings with the fan on low so you can hear the damper moving ,from defrost,to floor ,to panel you should duct diverter move,a soft muffeled thud,i guess would be an appropriate description,honestly this repair may be difficult if vaccum lines have become unhooked inside the dash panel, exposing them for inspection may require dissasembly of dash panel ,stero system,ect,if you are expierienced and want to take a look ,make sure you pull the air bag fuse or fuses,before removing anything inside the dashpanel,in fact just disconnect the negative cable on the battery,(both batteries),your best chance is to remove the blower assembly(the fan)and try to reach in the vent to remove whatever is stuck in there,or unjam the diverter,i have worked on motorcycles,cars ,trucks,heavy equiptment,aircraft,and helicopters,underdash panel access and repair in new vehicles these days should only be attempted by patient experienced mechanics,,very tight quarters,and lots of sh@! to break besides what is allready broken,be careful,hope your dad recovers ok,and good luck on the repair,aloha from maui todd0708

There are several possibility i will mention them all check out 1 by 1 ---------- 1) Low freon.The car will act like this when it needs a freon recharge. 2) Stuck door. There is supposedly a "door" (for want of a better term) inside the heating/cooling system that regulates temperature and/or cabin airflow. The door opens and closes according to the temperature and and dual climate settings selected. If this door gets stuck, it causes ice cold air to blow out drivers side and hot on the passenger side. 3) temperature sensor improperly reset. if the battery gets disconnected and reconnected improperly, it will cause a malfunction in the sensor responible for delivering the proper temp through the a/c system. so disconnect the battery and reconnect with negative terminal first; check all fuses that reference climate control, a/c , heater,remove for 15 seconds, reinsert or replace if necessary. 4) There is a leak in either your compressor or your a/c lines get it checked. 5) also a faulty drivers side temp door actuator can cause this problem. ------------- this all are the possibilities due to which this types of problem occurs. ------------- this will help.thanks.please do rate the solution.thank you for using fixya.keep updated.
