Steve, sorry it took so long to get back to you. My information source has been down and I just got it back yesterday. Anyway, What we need to do to test power to your climate unit is to pull it out of the dash so you can unplug the connector(s) from the rear. With key on, connector terminal E should be + voltage. Term D should be - or ground. If for some reason these term.S don't read right, look for any terminal that is hot with key on and dead with key off. If this part checks out, there is a problem inside the unit. I don't think you will find a fuse inside but there might be. Nowadays, you never know and I couldn't find a diagram to tell me. You can check in your area for an electronics repair facility or a dealer may have a rebuilt unit available. Wish I could tell you more. Jim One more thing, you may have 2 hot circuits at the connector. One for system power and one for the LED screen.
