I'd have to check the wiring diagram, but doesn't it get power from the load
reduction relay? Could be a bad relay or ignition switch... probably ignition
switch. When the Climatronic does not work, do the windshield wipers
work? If not, then either the load reduction relay or ignition switch is
no good.

The wipers work. Knock on wood and don't jinx anything....everything else, not related to the climate control works. Even the rear defrost and cigarette lighter.
I will check the wires from engine compartment. Upper left would be near/around the air intake. Yes? I did remove the air filter a few weeks ago. Maybe I knocked something loose.
Thanks.

If the ignition switch is faulty (a common malady on the EV), some things function while others do not. In my case, the engine started but the headlights would not, nor would the ventilation system.

Update....The system came back to life as I was on my way to pick up the new switch. I was going to forgo getting the new switch but decided to go pick up the new switch that I had called ahead and asked them to hold for me. When I arrived, there was no switch, computer had it in inventory but could not be found on the shelf. Frustrated and running out of time I left with out the switch. System has worked for about a week now. Strange but true. It has a mind of its own. Will still try and get switch replaced.
Thanks.
