Sounds like you have a faulty switch in that burner knob.
Its not. If you didn't have internet on when you turned on the computer you wouldn't of received the email. When you sign in to your email all emails that have been sent to you are retrieved. And also unless the computer is switched off at the wall it is not fully "off" otherwise it wouldn't know what the time is.
Yes, this is a normal operation for most newer cars, and is designed to help prevent windshield fogging when using the defrost function.
Some cars have a knob for the headlights. If this knob is turned left or right when pulled out, it changes the brightness of the dashboard lights from off to full brightness.
the knob you can pry off
The switch is probably bad or you aren't turning the knob all the way off.
Be specific what engine? what vehicle? I know of no knob on a stock 1980 chev is it stock?.......
Look at the turn signal knob. The end of the knob rotates back and forward. For the dashboard lights to be on, this knob must be rotated to the first click when rotated away from you. The next click turns on the headlights. However, this knob should be turned off when turning off the car, so as to not wasting the battery. Unfortunately the car doesn't have an 'auto' option for the lights.
Check to see if the knob that dims the lights on the dash is turned all the way off.
overdrive is turned off. This is usually controlled by a button on the shifter knob. Press it to turn of the overdrive, push it again to turn it back on.
Check your headlight knob, if it is turned too far, it will leave the dome lights on. Just back if off, you'll feel the click when you turn the knob. If that is not it, then see a certified mechanic.
I can't believe you have the same year of pickup with a knob issue like I do. Only mine is off, it comes off real easy, I need to know how to put it back on. As far as I know, if you just pull hard, it comes off!
