    I have an 06 Columbia with a Detroit. Engine brake stopped working this evening. Light comes on when I hit the switch but no engine brake. Same thing happens with my ac. Turn on ac but my compressor doesn't run and it's brand new. Is there something sinister at play here or do I have two separate issues going on at the same time? All fuses and relays are good as far as the ac goes. Can't find one for the engine brake. Thanks in advance for any and all help.

    how is the clutch feeling? any problems slowing the shaft?
    you're right, likely electric fault.

    I unplugged the fuse for the ecm and the jake brake started working again. No movement on the ac issue yet but it's back in the shop for that.
