2002 VW Passat Dashboard Lights Go Out While Driving
My car always starts up just fine, but it honks whenever I turn the key. Then
as I drive my dashboard lights that say mpg and outside temp., slowly dim
from the top until they go out. I've replaced the battery and this is still an
issue. It also gets much worse on warm days. Because my car is so old, I'm
hoping this is an issue I can ignore, but also I travel 4 hours on a regular
basis and want to make sure it won't shut my car off. I didn't have this trouble
until I replaced the thermostat, but I also didn't drive it very much until
recently.
