Seeking help, I swapped out the radio in my A4 , unplugged the old and jumped into the harness for a pos and neg and speakers for the new,, and now i have no power to my climate control, I have not shorted any wires , that i am aware of and I have checked all the fuses next to the drivers door, and under the steering column and there all good,,, So I ordered a new Climatronic control unit and again, it wont power up, I'm thinking others have had this issue so I'm calling out for help, its hot here in Florida with no A/C

I'd refit the old radio to see if that resolved the problem first.
