Ignition switch problems
About 2 years ago I started having dying issues and my instrument cluster flashing like someone was cycling the switch. I also had a bad PASSLOCK deal going on. I cut the wire to disable the passlock after replacing the ignition switch, lock cylinder and PASSLOCK. It would lock me out if I turned the key too fast.
Now six months ago, my blower on my heater/AC would start and stop working whenever it wanted. A month ago my car started having a very inconsistent delay of turning on ign0 circuit. My remote start that bypasses the switch always works. So I replaced the switch. I have 12v going in and when it is failing I have 0 volts coming out on either ign0 or on the heater wires. if I wait it usually works, but if I apply power to either circuit at the switch momentarily everything works fine until I shut off the car.
I have isolated the remote start by unplugging the inline jumper harness and going back to stock and the symptoms remain. I have now plugged it back in so I can start the car. I keep coming back to the switch I've replaced twice already.
Ign1 and ign2 seem to be the only power coming in and they are always live as far as I can see.
I have wiring diagrams but can't find one specifically on all the errors for the ignition switch.
Sometimes I get the service vehicle soon light if it takes too long to get power but I think that is because ign0 isn't giving power to the BCM
