This set of procedures is intended to help replace the panel/defrost and floor mode door actuators (small electric motors with a position sensing capability) as a result of an EATC self test with codes 1263 and 1264 respectively on a 2007 model Town Car. This should be the same for the 2003 and up models, but there may be variations. These models use 5 electronic actuators, but only the panel/defrost and floor mode door actuators need the dash to be removed for replacement. The 2 blend door actuators and the air inlet mode door actuator can be replaced easily without removing the dash. I have included all the actuator replacement procedures in the event that you may want to do all 5 at the same time and be done with them.
So the place to start is the confirmation of the panel/defrost and floor mode door actuator failures. The two mode door actuators control the air flow through the vent ducts into the cabin, so by manually selecting the EATC air flow to the ducts the problems can be quickly confirmed. The first attachment gives a description of the airflow in the last 3 pages to help confirm a problem or not.
The battery negative terminal must be removed for at least 1 minute, but 5 is better, to de-power the air bag systems.
I have combined some of the 13 procedures into groups in order to keep to 5 attachments and therefore one post. The second attachment identifies all 5 actuators and gives their replacement procedures. This is provided to help with the location of the actuators when replacing all 5 with the dash removed. The panel/defrost and floor mode door actuator replacement procedures in the beginning of the second attachment lead to the third attachment and the fourth attachments and then to the combined Instrument Panel procedures in attachment 5.
The Instrument Panel appears to be removed with the upper steering column and steering wheel attached so it is going to be very heavy. This is quite different to the procedures for the 2002 model and earlier.
Good luck.
