Sounds like there is a power drain somewhere. Have the entire system checked while on the car. Bench testing is fine, but many times I have seen things that pass the bench test, but fail the field test.

Also using a muli-meter check each fused item in the fuse block for a power drain. Look for amps being drawn by removing the fuse and using the MM to complete the circuit.
