I have a 91 Vette and am having a problem with the automatic heating and
ac mode on my car. If I try to do with auto the light flashes and when I check the codes
I get an 01 and an 02 which means a heater door circuit fault. Where do I find information
to tell me where to go next.

The auto mode will not give me any ac and the motor is at 0. If I do the speed manually
it works.
