So I ran the self-diagnostic test on my AC unit (05 TL). Here are the codes that the system can generate:



My system spat out the following codes:

1) E - sunlight sensor circuit
2) I - open in the driver's air mix control motor circuit
3) L - open in the passenger's air mix control motor circuit

For those of you who may be more specialized in this (or have experience with this), do these codes guarantee me that these parts are, in fact, bad? Should I order the parts now or wait and have the problem looked at? If I order the parts, is it an easy (easy is subjective) do-it-yourself job? Any of you have experience with this?

I have an appt. scheduled for early next week, but if I can get some insight ahead of time, it would help.

I believe the part numbers are as follows:

79166-SEP-A02
80510-SDA-A41
79160-SDN-A41

I hate cars

An open in a circuit can be anywhere in the circuit, not just the end device.

A sunlight sensor code will be thrown many times if the test is not done in direct sunlight. I've never run the test on the TL.

Lets back up, what is the problem?

Yesterday I noticed two specific things (during my drive to Little Rock):

1) AC is not as cold as it should be.
2) It seems that when the temp is adjusted (e.g., going from low to, say, 75), the dispersed air appears to remain the same temp.

Everything seems to be functioning properly. The AC is still spitting out cool air (though not as cold as it should be); there are no fogging issues; the compressor is working, there are no awkward sounds; all of the fan levels of the AC still function; etc.

No one? Not a single person has experience with this?

This might be a bit late to the game, but one of your air mixer control motors is failing. I had the same issue and it was the passenger side air mixer motor. They are about $100. I hope this eventually helps.
