Hvac Code 41 - 92 Es300

[flippu10]

Does anybody know how to fix this problem. I did a search and did not find anyone with this problem. The desciption of the code based on the posting is "41 ....................... Air Mix Door Servomotor Circuit".

SK has a lot of postings on the diagnostic procedure but I did not see any on how to fix. The hvac blows cold air all the time without regard to the temperature setting. At times, it will blow warm air all the time without regard to the temperature setting. Each time I turn the car off and back on, it seems to randomly do this (always cold air or always warm air). It's getting pretty cold in Chicago now and I'm afraid I will not have heat when it's really cold out.

Can someone give some tips on where to start. Thanks in advance.

You may have a rod thrown on one of the doors.

Pull back the carpet by the gas pedal and you will see the hvac system .

You can see some stuff from the passanger footwell also.

Make sure all the rods open and close the doors freely.
