Installed paddles on G37x Coupe but won't upshift

Hello

I have a 2010 G37x coupe and I just had paddle shifters installed since the X doesn't come with paddles from factory. I purchased oem paddles and it will downshift but not upshift, everything was installed and wired correctly as far as I can tell. Does the car need to be programed or something?

No programming. Entirely plug-and-play provided the harness came preinstalled in your car.

Do you have a multimeter and do you know how to check continuity? If so, you can check the paddle shifter switch itself.

Here's a quick tutorial on testing for continuity: Fluke Meters, just FYI.

Set the meter to read continuity and disconnect the wiring connector for the paddle shifter.
Place probes on switch terminals (pins) NOT the connector itself. It does not matter which probe to which pin. Your meter should read "OL" (open line/ loop).

Now, use a strong rubber band to pull and hold the paddle toward the steering wheel while you touch the probes to the pins. Your meter reading should change from "OL" to a numeric value and may even beep. This indicates the circuit path is closed meaning the paddle switch is good.

If the meter still reads "OL" when you pull on the paddle, then the switch is probably bad.

OK I'll give it a shot. Thanks for the detailed reply!

you can open up the paddle, and bend down the little metal piece which slides to make contact and repair the switch. I have done it before, not too hard.
