Hey, mister_rf. I hope all is well with u. I just got around to connecting the mirror and timer. I had to have some body work done to the truck and just got it completed. I couldn't find a switched power source in the door. So, I have both power wires hooked up to constant, and control fold/extend with a SPST switch. However, the values keep fluxuating and the time duration will not remain constant, so I may have to use a fixed value resistor instead of a POT. I was making adjustments for about an hour. The weird problem is that, in one direction (when the relay closes), the relay buzzes like a piezoelectric buzzer, when the time interval is complete (after the mirror reaches its extended position). Now the mirrors will not fold at all anymore, even though I can hear the relay click. I even noticed that when I rev the engine, it will make the relay buzz! Its really weird... Any ideas and possible solutions to these issues???
