Blend door actuator

[kd7kmp]

Well, I've got a noise coming from the center of the dash near the base of the windshield. I ran a self test of the EATC and came up with code 02--blend door. The thing is that I still get heat and cold when I adjust the temp. The noise is a clicking that is there with the EATC on or off. Sometimes it will stop, though. Do I need to replace the blend door motor or is it something else? Thanks.

It may not be the door thats bad. When the door moves so does a contact pointer on a resistor. It feeds a voltage back to the ETAC telling the position of the door. If there is dirt or corrosion on that strip the ETAC gets a false reading and may keep trying to move the door. It's a very simple assembly, getting to it is where the work is.

A broken gear inside the BDA module will cause that exact symptom. If your EATC has complete control of the teperature, I'd just turn the stereo up louder

I've read the write-up on SHOTimes.com and it only talks about a few harnesses that need undoing to pull the dash back. Will any vacuum lines need to be taken off? Any snags I can expect? I have access to Alldatapro online factory manuals. The factory manuals listed A LOT more stuff to remove. Thanks.
