Late Challenger Smart Door Glass Controllers

One thing I have found on the DP window controls is they do not like 16v systems.
They will usually work when the car is not running , but when the car is running with a functioning alternator , voltage approaches 18-18.5 volts and the control module shuts down .
I fixed the problem on one of the DP's I work on by using a Runtz dropping resister that is made for dropping 12volts down to operate 6 volt gauges on cars that were converted to 12 v.
