Default 03 ram defrost, vent , floor hvac problems

hey guys , im new to this furom , and also new to dodge stuff , i just bought my first 03 ram 2500 quad cab with a ctd last week

id take is back to the dealer where i got it but hes in illinois and im in pa sooo here i am stuck

when i have the vent **** on one setting it may take a few minutes before it goes there , sometimes i can have it on defrost and it will only go to the floor vents no matter where the **** is , sometimes i can put it on defrost and it will go right there , sometimes i can put it on dash vents and it will go right away and same with floor vents

its just really wierd , i asked a few guys on this drag race furom i go on everyday and a few said it may be the blend air door , it just seems wierd and makes me think it may be the actual control **** that is fualty

anyone came across this yet?

thanks ted

sounds like a vacuum problem, since thats how most of the manual climate controls work.

thats what i tought vacumm being a chevy guy i wouldnt even ask this quesion

but being new to the dodge family i was told on this model with the cummins it does not have vacumm it is all electrical , i had the center dash off already to put a radio in it and the plug that goes into the back of the control unit looks fine

its just hard to belive that a truck with only 61,000 is having this wierd problem

here is a link to a repair guide a guy gave me http://home.hot.rr.com/jlnun/BLEND.htm it tells how the system works it just seems like a servo or the control panel ****

the issue I am having trouble with is that you say it sometimes works and sometimes dont. So its either a short or sticking....

ok i went out for a drive in the truck today , here is what it did

had it on defrost and floor , it was working great coming out both places , i turned the **** to dash vents only and air came right out no where else , had it on that position for a bit , then moved it to the floor only and it wnet there right away , figured ok must be my lucky day , turned it to defrost only and it didnt do anything


im just trying to see if anyone else had this problem before i take the dash out and the hvac to see whats up

Here is an actual web site that shows the fix.There is a Bulletin on this issue.http://dodgeram.info/tsb/2002/24-004-02.htmI had the same problem, no defrost or floor air. Graually it worsens untill all you get is air only out of the bi-level, no matter what heating/AC setting you choose from the control ****. The fix was replacing the Panel Door Actuator and the Blend Door. This was all done without removing the HVAC!!! Yes, there were some removal of Dash and Glove box, but not to the extent of REMOVAL of the Whole Dash and HVAC Assembly. I walked out the door for $569.00 The actual problem on my truck was the plastic housing on the blend doorwhich became stripped and the panel door actuator could not turn the blend door any longer in any position.

The Pencil is pointing at the WHITE PLASTIC BLEND DOOR HOUSINGIS WHICH TURNS THE BLEND DOOR
[hr]
Bingo, that was my problem. the Blend door themselves are in great shape, no cracks but the plastic housing is stripped! Save your paper work cause if Dodge does get a class action suit in a few years from now, you will have the paper work.

Not to be stupid but what did you need to replace the actuator?

Hi, Are you saying it cost you $569 for the actuator and blend door???

my 04 1500 the blend door broke off at 40 k miles. so I pulled the blower motor and reached up inside and removed the broken door through the hole for the fan. now ac is working ok but not as cold becouse pulling air from inside cab and outside air at same time.

How difficult is it to get to the blend doors? Mine works properly between the positions, but my problem is getting heat on the driver's side. I've been told it was the blend door. Is it broken or stuck closed? The A/C works perfect on the driver's side..

My concern is that I will fix the blend door, and then it will break AGAIN somewhere down the road. And it's a pan in the @$$ to do it. I was hoping they would come up with a mod. I know that someone made a metal blend door that fits the jeeps.

your concern is a real one ... after discussing it with parts/service (a member here very knowledgeable and nice guy) he said that dodge has finally switched manufacturers for this part and they've seen a stop/slowdown in the vehicles that return with the same problem ... that was enough for me

Great news!!!! I would really rather order the part directley from him. I wouldn't put it apst them to give me an old one that they have nad in the back room for 2 years. Yes, I know parts/service is a great guy and full of great info!

I am having this same problem. No heat on the drivers side and no AC on the passenger side. Will replacing the blend door fix the problem?

Thanks

Well Ted I have the same problem. This is a issue with chryslers manufacturing. They us all plastic components on the heater mod and they do not last.
I have a 2994 1500 4X4 and have had it repaired for this during the warnnety and now that it is oiut of warrenty we are left holding the bag.
I'm a 30years into the repair business and this one will cost us some money. You are going to have to get the dash removed to find the issue or have it checked only at a dealer that has a scanner that can tell you which blend doors are bad.

Good Luck ED

On my 2004 the recirculate selection doesn't work, and I'm getting cold air in the cab. The selection of heat/cold seems to be okay. I dropped the blower, and sure enough the dorr right above it is broken. Can I push it in a certain position to block the outside air?
