In the past, when I have tried to cut down the voltage from a variable solar panel into a DC motor with a 10 watt resistor, the resistor always got too hot.

This case is a somewhat different; a solid 12v DC source and a computer that is apparently looking for 1.5 ohms and all it sees is 0.8 ohms from the new power window motor.

This question arises from a restomod project where I am moving most of the electronics, engine, wiring harness, interior, dash, etc. from a 2014 Camaro into a 1970 Malibu.

How would you fool the computer and still allow the motor to function?

Somehow I missed the below response, mea culpa.

It's the body control module (BCM) in a newer Camaro.

Here's a pic of the semantics in the service manual...

    \$\begingroup\$ I find it hard to believe that "a computer that is apparently looking for 1.5 ohms." What gave you that idea? Which computer are you talking about? \$\endgroup\$
