I have a 91 coupe and I have removed and cleaned the ignition switch once, due to car switching off going over bumps this was a few years ago and no issues. Recently I turn key and car does not turn over on initial try but will start a few tries later. So now after having replaced the switch and key would not turn and radio and HVAC have power and won't shut off. So I removed and re-installed now key turns now key turns but no power to radio and HVAC. So I replaced with old switch and same thing. I have checked the ignition fuse in the drivers compartment it was good and I have also I have replaced the main relay as a PM, not sure where to look after that?
