I never had a problem with it. But I was running 05 GTP seats. And when running those, there is no thermostat to turn the heater on and off. So it is high all the time regardless of switch position. But again, never had an issue at all.
Switches are sold since I demodded. I wanted to do something like that, but wasn't sure what to use to coat them with afterwards to give the texture. I will have to remember the SEM stuff. Thanks!Zef.. if you wanted to finish that off. JB Weld that seam. Sand it down.. then pick up SEM texture paint and SEM flexible adhesive Graphite.
