I brought the Tahoe in to take care of some unfinished business. When we got the Tahoe it only came with one fob that was for driver 2. The r/s system only works on driver 1 so had to do some reconfiguring.
Reprogrammed the oem fob to driver 1.
Programmed the replacement r/s key fob.
So now whatever she does with either fob will be driver 1 which is cool. All I have to do is press 2 for lean back mode when I drive it.
Meanwhile I looked into the autolights. Autolights on that thing are like ours where key on fires up low beams (hid in this case), key to crank kills them and key back to run fires them again. A 180 ohm resistor brought the signal down to 1.8v which fooled the bcm into thinking it is daylight. Might come back tonight and get it done.
