2001 grand caravan blows cold air on passenger seat- driver and back hot
I know there are several posts concerning issues but I have not found one that I thought was my case. I have the heat turned on and it is hot in all types of settings but the floor on the passenger side blows freezing cold air all the time when on. I will check the back vents but the kids in the back complain it is hot so I am assuming it works in the back. I have a side button for driver and passenger heat and cold air to adjust the temp. the back has a turnable **** to make it low , med and high; I also have the same **** for the front control the the air control. I have read blend actuator, blend door problem, climate control module could be the prolblem but not really sure what to ask for to order a part. I should let it freeze my son out since he is going through the 13 and I know it all stage but my feet kind of get cold from all the cold air on his side. Thanks for any help and I am going to try to fix this myself unless it is really complicated or if I could possibly blow the garage up fixing it then I will take it in.

Tammi,
Id bet its the actuator for the passenger side
ive posted a photo of what your looking for
http://
when you remove it try and turn it by hand either way if it rotates its shot
if it doesnt rotate ther are some tests to do
you will need a testlight and a voltmeter
should be no reason why u cant do this yourself with some basic tools

this is to hemi4speed
I am sure there is a way to reply just to you but I was not sure how so I hope you get this. Great photo and thanks for the fast reply. I know this is going to sound stupid but the photo you sent me, is this under the dash board on the driver side or is under the hood. I have seen other post talk about the dash. ThanksTammi

Tammi, there is a common issue with the 2001 model year for cold air on the passenger side. There is a metal rod that goes from the door actuator in the picture (which is located right above you gas pedal) inside the housing to the blend air door. They made the rod too short so it comes out of the door and won't move it anymore. There is a new rod that is longer to correct the issue. There was a technical service bulletin issued for it

10. Reinsert the plastic external stop to the blend air door shaft in the same position as
it was removed. Rotate the blend air door shaft by hand to ensure the plastic door
stop stops rotation of the shaft between the stop bumpers in the housing.
11. Position the blend air door actuator onto the distribution housing. If necessary,
rotate the actuator slightly to align the splines on the actuator output shaft
with those in the blend air door linkage.
12. Install and tighten the two screws that secure the blend door actuator to the
distribution housing . Tighten screws to 2 N·m (17 in. lbs.).
13. Position the heater core shield onto the distribution housing. Be certain that the two

18. Perform the heater-A/C control calibration procedure:
a. Turn the ignition switch to the ON position.
b. Simultaneously depress and hold the Power and Recirculation buttons on the
heater-A/C control for at least five seconds. The manual heater-A/C control
Delay Light Emitting Diode (LED) and Recirculation LED, or the Automatic
Temperature Control (ATC) heater-A/C control Delay and Recirculation graphics
will begin to flash when the calibration procedure has begun.
c. The calibration procedure should take less than three minutes to complete for the
manual system, and less than twenty seconds for the ATC system. When the
LED’s or graphics stop flashing, the calibration procedure is complete.
d. If the LED’s or graphics continue to flash beyond the time stated above, it
indicates that the heater-A/C control system has detected a failure and a
Diagnostic Trouble Code (DTC) has been set. Use the DRBIII® scan tool and9. Install the new blend door shaft through the blend air door and into the housing.

Ya Tammi this is all under the dash (Center to passenger side is usually where airboxes are located, more room as the drivers side is full of pedals and steering shaft)
Tizzy is right I forgot all about that silly rod check that it has not come off first then check actuator like i prescribed above

Ok, it's an old thread, but I wanted to ask some clarifying questions to try and solve my own issue.
I have an '06 Town & Country, dual zone heat, but not the fancy electronic type with thermostats and things. If I want more heat, I slide the temp selecter over to the hot side.
Anyways, I just noticed recently now that things are getting cold around here (20's) that I've got ice cold air blowing at my shins in the driver position, regardless of the vent selection or temp selection. If I can reach down, I can feel vaguely warm air floating out of the footwell vent if I have the fans on HIGH and the heat cranked all the way, and the foot vent selected, but it doesn't seem as hot as it should be and the volume of air coming out seems very weak.
I can get piping hot air coming out of the drivers side face-vents (for lack of a better term) as well as the windshield vents. I believe the passenger side is ok, but I'm not sure because I don't often have someone sitting in the front passenger position.
Reading this thread, I thought the answer was the blend doors, but after thinking about it, if the driver-side blend door was not functioning properly, wouldn't I have the same heat issues on the drivers side face-vents as I do the floor vents? Is there a common place where cold air can force its way into the cabin near my feet?
If anyone is still checking this old thread, I'd appreciate your ideas or input.

Thanks for the thought, I checked and I don't have a cabin filter. Where it would be is just solid plastic, no access door or anything. I will do some more poking around when I have the chance. It seems that the heat is working as it should, but that I have cold air coming in from somewhere--I can feel it coming out around the cupholders and in the bottom cubby of the center console.
