Control Module above break pedal is vibrating and making noise when car is off

What is your question?

The other day I fixed the a/c in my truck and went to start it a few days later and something happened. The truck started fine and I turned on the a/c and it died. I heard a weird noise coming from under the dash and i felt around till I found a control module vibrating like crazy. I thought that part was bad so I ordered a new one and when I installed it it's still doing the same thing. The truck won't start and that module is going crazy still. NEED ADVICE
