Heat Seat/Phased Width Modulation (PWM) question

clarker63 · 12-09-2016, 02:01 AM

Hi, I've switched from manual/non heated seats to full memory/heated seats, but I'm not sure if anyone else has retro-fitted these into a 'base' level car...

Can anyone confirm that the small module under the passenger seat has the PWM unit in it, so I only need the console switch to make it work, or do I need something else in the car? (obviously I need to ensure the wiring is all in place!).

Thanks

Did you check realoem? It will show you all the components.
