W124 Climate Control Unit no response
 

I pressed the CCU to get the AC working and nothing happens. I pressed all of the buttons and there is no response. I went ahead and checked the 30 AMP fuse and it looked fine. Had a spare and still nothing happens. When I was driving warm air was being blown inside the car without the blower. Bad Blower or the CCU unit? Any ideas? How to properly test..... Thanks!

I'm pretty sure there is another fuse in the main fuse box. I would check there.

If all the fuse are in tact and you can hear/tell that the vent pods are adjusting....Could be a bad blower motor regulator.

I could not hear/tell the vacuum pods were adjusting. Checked Main Fuse Box and found fuse#7 to be broken. Replaced fuse and CCU is now working again! Thank You both! :)
