Dodge Truck No Heat On Drivers Side
Well, on my trip back up to college last night I discovered that my '06 Duramax's drivers side heat is not working. With the fan on, and both 'sides' of the manual climate control all the way up to max heat, the passengers' side blows out blazing hot air, but the drivers' side is ambient temperature (cold). Tim, according to the diagram you sent: Item 10 is working; Item 7 actuator is working maunally, can hear door shut and open (I removed motor); Item 5 is working; There is NO item 2, the blend door is all together. Still no heat to drivers side. Dodge Mechanic: Tim Mohr, ASE MASTER TECH replied 7 years ago.
Unfortunatly you do have to remove the dash to access any of the blend door or fresh air door actuators here is a step by step proceedure this takes aprox 5 hrs in a shop so plan on a weekend at home good luck FLOOR - DEFROST DOOR ACTUATOR REMOVAL WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, DISABLE THE AIRBAG SYSTEM BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE. DISCONNECT AND ISOLATE THE BATTERY NEGATIVE (GROUND) CABLE, THEN WAIT TWO MINUTES FOR THE AIRBAG SYSTEM CAPACITOR TO DISCHARGE BEFORE PERFORMING FURTHER DIAGNOSIS OR SERVICE. THIS IS THE ONLY SURE WAY TO DISABLE THE AIRBAG SYSTEM. FAILURE TO TAKE THE PROPER PRECAUTIONS COULD RESULT IN AN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY. Disconnect and isolate the battery negative cable. Remove the instrument panel assembly from the vehicle. 16 HVAC Housing - Dual Zone Shown (Typical - Single Zone) Remove the electrical connector from the actuator.
Remove the mounting screws from the actuator. Remove the actuator from the HVAC housing.
INSTALLATION Install the floor-defrost door actuator to the HVAC assembly. Install the mounting screws and tighten to 2.2 Nm (20 in. Install the actuator electrical connector. Install the instrument panel assembly into the vehicle. Connect the battery negative cable. Tried to post diagram just pm me and I'll email it to you.
Hey maniac thanks for that but before I do this do you think it could be the heater core.I have lots of air moving and I have no problem moving the air from floor to window I just dont have any heat.and the heater core its up behind the steering column yes.I liked it better when dodge put them on the passanger floor. If you think it could be the heater core whats the procedure for getting at it. I have no wetness on the floor and my prestone is not going down I just have no heat.New rad cap, new thermostat and as mentioned I flushed the system.
Its starting to get very cold driving to work any help is greatly appreciated. I jumped another vehicles battery and the control to switch what area the heat comes from doesn't work now, I've checked all fuses, the armrest lighter fuse blew relaced it and the plug works but lost the feature to switch air direction for heat, I can switch to hot/cold, a/c still works I just cannot use defrost or floor airflow. This problem happened 2 yrs ago, it's been to the local dodge dealership and they cannot figure it out, I've even went to a junk yard and tried switching out the dash controls and still nothing. Hoping someone knows what this might be, main issue is getting defrost as the winter weather hits it's a pain not having defrost. If anyone has suggestions I'm all ears,thanks.
2000 Dodge Ram 1500 4X4 5.9l I have multiple symptoms. Symptom 1 - A/C Compressor runs no matter what setting(vent, floor, defrost, AC) the switch is set to. Symptom 2 - Luke warm heat when set to 100% hot. Symptom 3 - The faster I turn the fan up the colder the air coming out gets.
Known facts - New Thermostat, both hoses for heater core are very hot, heater core has been flushed, radiator/reserve is full, Actuator can be heard working when switching from cold to hot to cold, no problems with switching from floor to vent to defrost. Any ideas would be great because my mind is burned out on it. Bet the OP in 08 never figured on it running this long.LOL You say you don't have dual climate control but no heat on one side? Do you get the same result on def and vent or just heat. Sounds like a core problem if this happens all settings.The reason for this logic is its a longer distance to the driver side than passenger.Is the air flow the same? If not then you are probably looking at one of the two air doors your 'lucky' in the single zone since there is only one blend door and 2 flow doors.If the air flow is the same just the temp is off a heater core is the most likely target.You can try the active flush I described in a previous post and see if that fixes your problem or if not you will be stuck with a core replacement. If you still have the suitcase out this will be fairly easy to do at this point rather than flush it and reinstall and find out there still isn't enough flow for heat.
Just to let you all know there is a recall which could affect your heat. Mine had been replaced before I bought the truck but it was a shoddy recall repair.
Many thanks to Triangle Dodge in Aiken, South Carolina for doing the right thing and repairing the recall again. I have had NO heat for 3 years. Now my defroster will not defrost my windshield. We had to flush the heater core, replace the radiator cap and antifreeze and spend a lot of cold mornings at 5 a.m. To go to work before Daimler buckled and helped me out.
Thanks to this website, I am now looking at the blend door actuator as the culprit for the defrost being inoperable. Lots of luck to all. I love my 1500 but it was cold. Bill, welcome to the forums! As you can see this thread spans a 2 year interval and was hijacked at least 3 times.
To keep down confusion, just start a new thread rather than tagging on to another one. SO, to your problem. Are you running a gasser or Cummins? Diesels have a vacuum pump in front of the power steering pump on a common shaft that provides vacuum to the heater doors. Diesels are positive atmosphere since they are turbo, hence the vacuum pump. Fairly sure the gas engines work off their own vacuum, so I'd be looking at broken or disconnected hoses next to the firewall and under the dash (feet up, head down, backwards).
With the engine running, listen for a hiss, indicating a hose may be loose or broken. Barring that, since it moves from face to defrost (I assume), you may have an uncooperative door that may need a little lubrication at the pivot points. Or you could have a rat's nest lodged against the door keeping it from opening.
Just have to get dirty and look at all the possibilities. I would like to say hello. And introduce myself as another owner of a 2002 dodge 1500 4.7 with a heat problem. This place is fantastic and I'm learning tons of info about my truck. So here's my prob. Blast of heat.
Then cold air. Lowest setting = very little warmth to none. Thermosat good, = temps in lines going in and out of core.
2001 Dodge Truck No Heat
Someone had mentioned a possible replacement of a vacuum line behind the control panel??? I haven't read anything about this yet.
I was still going to give the core a flush - but I would like to find out if there is chance this could be the prob. Oh - and yes. My dash is cracked too.

Looks like a jigsaw puzzle. Not sure what would cause more personal damage.the actual accident or flying dash pieces.
