Cheap solution >>>HERE<<<
Is to be considered temporary solution until the defective parts are replaced/fixed.
As Vincentm notetd above we are talking either of:
1. Ignition key resistor contacts worn or very dirty - new ignition key with matching VAT
2. Ignition cylinder contacts (worn, or broken wires) - new ignition cylinder + new matching key with matching existing VAT
3. Harness issues between ignition cylinder and IPC (main culprit would be the big connector underneath the steering column).
I have the same issue right now, i have a new AC Delco ignition cylinder sitting in a box, for weeks now , just no info on how to replace it, in Alldata, ive asked here before but no response, i figure i can replace my turn signal switch new wiper pump wont work) as well when doing the Ignition Cylinder.
