This is a safety issue. Model value: The Grand Caravan was one of the first minivans to make it big in North America, and it's still one of the best. Namely that the blend door was not sold by itself, but rather the whole heater box assembly was sold as one unit and that whole unit had to be replaced to fix the problem. But having already visited the same junk yard I had just the van in mind to get a replacement door from. I do not have access to a component locator. Disconnect and isolate the negative battery cable. As of May 2015, the air conditioning will not work on the passenger side of the vehicle.
When I got home I put some white lithium grease on the ends of the blend door and slipped it back trough the slot I had made in the heater box. Or you can try recalibrating to see if it begins working first. I've searched the internet and found far too many complaints on this same problem for many of the year models. No one, I repeat no one should ever willingly put another persons children at risk! I tested the motor alignment by changing the heat as hot as it would go and back to cold again and I could hear the door moving as designed and stopping where intended. After letting it go for a few weeks I started some research and found several trouble shooting web sites like the link below and I was able to determine the blend door in my van was broken. I 'carefully' removed the blend door from the heater box, with a tire iron I found in the van.
But if the motor that operates the lock, known as an actuator, quits working, your convenience quickly becomes a liability. So I knew the shaft was no longer connected to the door. I disconnected the negative battery cable and let the the car stand for about 40 to 60 minutes. If that does not help it maybe the electric servo motor is bad or the switch on a dashboard may be bad. Lift the door panel off.
Thankfully I thought that far ahead when I started cutting. It seems the colder it is outside the cooler the air is coming from vents. But once I saw the broken shaft first hand I knew it wouldn't be easy to glue or repair the door and a replacement door would be in order. Every season I have to have my Blend Doors recalibrated because it won't allow me to redirect where the air is blowing. Vehicles found with damaged actuators must ave them replaced. Said that Transport Canada was responsible for them not paying!! One week has gone by and I called the dealer to see if the blend door has arrived. Outside, the package adds 17-inch polished aluminum wheels with gloss black pockets, a gloss black crosshair grille, black headlamp bezels and matching fog lamps, while inside there is an all-black interior with silver accent stitching and matching.
Then I decided to visit the junk yard again. I recalibrated as indicated above, same problem. This Van is my daily driver after all. Went to dealership with my letter expecting all to be covered. Set Mode position to panel.
So, I turned the van on and made sure the heat was set to the coldest setting and then installed the blend motor again. That dealer told me the same thing the first. Pry out the screw cover in the door pull cup and remove the screw. There's no way I want to try to get through winter without heat! Remove the silencer panel from under the driver s side of the instrument panel. Underneath of the dash to the right of the steering column on the driver's side is a cam. I have pulled most of the dash apart and cannot find the actuator. How can that be omitted from the letter? Calibration Test is running when rear wiper and intermittent are alternately.
Remove left side lower column cover. I am having this problem fixed and if possible speaking with the media as to inform any potential new customers of this issue. Then back down to cold, then up to hot. The coolant is full, the thermostat does work, both hoses to and from the heater core are hot, one more so than the other. Late spring sometime the heat in my 2003 Dodge caravan went out.
Feel free to contact me if you have questions and good luck fixing your blend door for a fraction of the work and cost of doing it the 'correct' way! If I had to do it again I'd; a: take better pictures so I could explain this better. Service bulletin fix and car heater not working repair cost Chrysler lists the reflash time at 0. I've also heard to try this while driving obviously as the passenger - Steve V. Push Rear Wiper to exit. Try disconnecting your battery for a while to clear the memory. Power door locks are a nice convenience to have in your car. I had no heat and the fix is to replace the whole heater box that contained the blend door.
