Absolutely.
Locating it is quite easy: think of where you insert the key to turn on the car. That is the ignition switch. You can replace the electrical part separately from the mechanical part.

Should have asked here first. Easy to test the battery.

Nope. Alternator will not produce these symptoms.

Not really. The dirty contacts in the ignition switch cause electrical noise on the 12V line.
This is then carried onto the k-bus and i-bus databusses due to the pullup resistor in the instrument cluster
The noisy voltage line causes data corruption on the databus, resulting in databus messages being misinterpreted or not interpreted at all.
Hence devices which are controlled by the databus - almost everything - show strange symptoms.
Replace the ignition switch with a BRAND NEW one, and all your problems will go away.
Easy DIY job, straight forward and simple to replace.
