2004 Dodge Ram 1500 Q&A
2004 Dodge Ram 1500 Question: AC blowing cold air on driver side only
You don't mention if you have Dual Zone temp controls, but judging from your description I have to assume that your vehicle is equipped with Dual Zone. In this case the "Blend Air" doors in the heater housing are independent of each other and each have their own actuators allowing the individual adjustment of tempurature from right to left vents. In a single Zone system, the blend air door is one piece, thus the temp difference between right and left vent is not likely if the any of the components failed. The HVAC control head, wiring, actuators or blend air doors may have failed. A competent technician should be able to easily diagnose which component has failed. - Johnny Mopar
If you have a 02 to 06 dodge ram and the driverside is cold and the passenge side is warm. The fix is to charge your a/c system. Your low on refrigerant and the evaperator is not full. - Visitor
Very common problem, normally the door shaft is broken and the door remains in close positon. Read remainder of comments The most common problem is the HVAC box. Inside 4 moveable plastic panels control the air flow to different chambers. The common issue is the plastic shaft breaks. The only way to replace these panels requires a complete dash and HVAC removal, 6-8 hours of labor, AC coolant needs to be drained and later refilled. Mine broke twice, first one was the lower panel under warranty and the second had 2 broken panels. I did it myself and replace them with metal panel from "Heater Treater". - Visitor
So whomever gave advice to charge the AC... Brilliant! I have a 2004 Dodge 1500 4 door with HemP power. AC was only blowing on drivers side and passenger's side was blowing warmish. Took advice to charge AC as follows: 1. Go to your local auto store and buy the can of AC juice with the hose attachment and gauge built in. 2. Go home or to somewhere you can work without being bothered 3. Start your engine and turn the AC on Max 4. Hooked up can of AC juice to the LOW side port (passenger side near the fire wall for HemP) 5. Shook can well and hooked up can to AC port and read gauge... darn thing was low. 6. Squeezed trigger on can and every 3-4 seconds turned upside down and back upright. 7. Charged to where arrow said (accounting for the temperature was built into the gauge) 8. Noticed AC system that was really noisy became much quieter as charge approached the green 9. Disconnected can from AC port and replaced cap. 10. Sat in truck and enjoyed the chilly cold that had replaced the weak a$$ AC I used to have. **Disclaimer: cannot guarantee you will get the same results but cold is now blowing out of both sides of the dash vents. - HemP04
When I turn on the heat, the passenger side is receiving warm/hot air but drivers side is receiving cold air.
