The mode door actuator is behind your radio CDM to the right of the accelerator pedal. You'll need to replace that one (or free it up) to get the mode off defrost.
Here it’s doing the full flash. Then I poke enuff buttons and it does this but still blows defrost.
I'll wait until Beryl blows on through here before I can get back out there. Thanks.
I got back to tracking my issue. It was in fact the mode actuator on driver side. It did not make any noise but it only moved about a 1/4". I took it off and opened it up. Plugged it back in and touched the mode buttons and found it bound up. The motor was running but the worm gear was not moving. It must have come apart inside. Well, it is 33 years old.
