Replaced heater blend door and accuator but accuator will not work


What type of car is this? There should be a way to scan the climate control system for fault codes. When you mention that the door wiggles, it makes me wonder if the door movement is restricted in some way.

Air conditioning only blows cold air.


Can you hear the blend door moving when you change the temp from cold to hot or vice versa? If not, then you need new blend door actuator. Also check the heater core for any blockage. (2 ways to tell....run the car til normal temp, and turn on the heat and feel the hoses by the firewall...if one is hotter than other, there is a blockage inside the heater core. Or disconnect both hoses at firewall, and put garden hose in one of those 2 open tubes and turn on the water...good flow or weak flow coming out of heater core tube? Weak flow means blockage) If there is a blockage, time to get new one.

All vents were blowing air (hot/cold), except the middle two vents. I took off the dash to access the the middle vents. After doing this I found the foam vent flapper was closed. I can either force the...


If your heater is electric control then you will have accuators that open/close then vents when you change the temp settings. If this is the case you will need to determine what accuator is out to replace it. Most vehicles will use the same accuator, meaning, if your car has 3 accuators then most likely all 3 will be the same, but not in all cases.

The blend door is in the HVAC box located under the dash on the passenger side. A faulty electric door actuator is often the cause of this - there is a really good video on YouTube showing location and how to replace it.

My 1993 Mercury Tracer doesn't put out any heat and the temperature gauge stays on cold. I changed out my thermostat and nothing has changed. What else could it be?


I had the same problem with my daughters 93 Tracer today. I fixed it by going under the dash (on the drivers side). If you move the temp lever while looking at the parts on the heater, you'll probably see, as I did, that there''s a white plastic piece with a groove in it, that a little bent wire fits into. That wire accuates the temp control. Mine had come out. It has a little white attachment that fits behind the bottom (black plastic thingy) that holds the wire in place. I put a drop of superglue in it and put it back on. It now works fine! Hope that is your problem too. Good Luck!

the part u are referring to is the temperature control blend door actuator motor, it is about center of air ducting, in order to access the part u must remove the entire dash assembly, not a job for a DIYer, 12-15 hour job.

No heat comes out only cold air. It started with one side going out then the other. What do you think it could be?


If you have automatic temp control, the blend door accuator could be bad. If you have normal temp controls, the heater control valve could be bad.
