ZEEJM,
I have a similar issue with a Mountineer with DATC. I am good on the driver side but I have no cold on the passenger side. The boss is not happy!
turning the dual control on or off does not effect it.
So changing the actuator fix the problem? I assume there is one on the right for the pass and the left is for the driver, correct?
I need to fix this quickly before my wife just takes it to the dealer.
Thanks in advance for the help.
Big Rondo -- Great write-up. Thanks for taking the time to share your knowledge with everyone.
I thought I would update some information for those that have the DATC.
Problem – Only cold air out of drivers side vents
First I did have the freon level check. It turn out I had a small leak. I had the line replaced and the system charged.
I still only had cool air out of the Passenger side vents when the fan was on highest setting. Low speed was warm air. It took approximately 15 mins to get that side cool on high. It still was not as cold as the drivers side.
I decided to replace the passenger side actuator. I took pictures if someone wants to help me post them.
Procedure time – 1hour 15 min. (with an adult beverage)
1. Remove center consol as per original instructions.
2. Remove passenger side dash brace from floor
3. Remove lower floor vent duct work
4. Remove glove box. – Pull the sides in to permit it to open towards the floor and then remove the 3 screws.
5. Through the glove box hole you can access the top screw towards the front of the vehicle on the actuator. You need a 6” extension on a ¼” drive
6. The lower screw towards the front of the vehicle is a little trickier. I cut a v-notch in the side of the glove box opening about ¾” from the bottom. That permitted access to the screw with a 6” extension. (picture would help here)
7. Lower screw can be accessed from the bottom.
8. I had to cut the dash as per the other instructions to get the old actuator out and the new one in.
Good News – The new actuator went in great and dash does not look any different.
Bad News
1. Still have issues. The passenger side now blows cold air at low fan speeds but still not as cold as the drivers side
2. Still takes about 15 mins to feel a difference in the air on the passenger side.
3. Temperature difference is noticeable if I have the air conditioner on and the defrost selected or floor level.
Does anyone have any other suggestions?
Does this need reset or something?
