The temperature gauge and fuel gauge lights are gone and now the radio/clock lights go out but come back when I firmly"tap" the panel. Also, my headlights flicker and dim whenever I use my power windows or accelerate. I had my alternator replaced about four years ago and these issues seem to have started after that. Are they related?

Hello,

Yes they can be related if the alternator is throwing AC voltage. this guide can help confirm the issue:

Set the voltmeter to AC voltage when testing, you should have none. Please run down this guide and report back.
