This a recent problem: the control panel for the heat and AC, including buttons for the compressor, air recirculation and rear defrost goes dead. It seems like it works in the mornings and then later in the day it goes dead.

I checked all the fuses listed for AC in the fuse box, all looked OK, and a shot of WD40 onto each fuse connector made no difference either.

These intermittent problems are crazy to solve.
