Radio lights flicker now and then
Just had 90,000 mile check up battery chec k was good while driving my light in radio flickers radio reception is fine
also heated seat button works when car first starts but after driving a while it won't go on
Most likely two separate issues. On the heated seat/s usually the wires under the seat go bad and blow a fuse or they get frayed and have intermittent connection. Radio issue is possibly a loose connection in dash for radio.
the heated seats may be working properly, they are designed to shut off at certain temperatures and not to come back on until they are below that. also a question about the radio problem. do you notice anything else getting dim when this happens? and does it happen mostly on decleration?
may be your light wiring for the dashboard is shot circuiting
No other light in dash flicker only radio it happens whether foot is on the gas or not doesn't matter and happens once in a while not every day
For the seat check the wiring under the seat. These wires flex every time you move the seat. For the radio might just have a light bulb loose or maybe loose wire under dash.
