Z3 Heater Control Repair

Hi All,

This is my first first post. I have to thank all of you for the tremendous info and great pics. I used your experience to repair the "notorious" broken plastic pin issue on the temperature control.

Following your radio and control panel removal/release instructions, I was able to rotate the panel within the radio opening to expose the rear side. Yep, the plastic pin broke off and was still sitting in the track. Using it to determine what would be a proper substitute, I happened on the idea of using a 1/8" diameter x 1/2" long aluminum pop rivet.

After protecting the center circular dashboard opening (where the temp control lives), I drilled through the control arm at the exact location of the old plastic pin. In order to expose as much of the rivet as possible on the "track" side, it was important to ensure a tight fit for the rivet so the riveting tool could release it with only 1-2 squeezes.

Voila. Works really well. I suspect that other parts of the car will break before this does.

I hope that helps someone out there. You folks saved me a lot of dough.
