Re: Seat Heater lights

Over here in Canada the switch is about $150 cnd.  I sure like to be 
able to replace the bulb.  I have no problem handling the soldering 
gun.  But dismantling the switch looks tricky.  I see the red plastic 
cover from the front.  I guess to dismantle the switch I have to take 
it from the back.  But the switch seems solidly assembled, not meant 
to be dismantled.

  Has anyone got experience in dismantling one ?
