[T2] Headlight problems.

[Bob Pratt]

Hi Chris,
Replacing the original bulbs was the first thing I did. Today I unplugged the bulbs and tried the turn signals and brake lights again. Same thing happened. I was going to change the headlight switch with one I had, but the spare I have is for  a 72-79 bus. So unless I figure that it's not the switch, I'll be ordering a new one.

>> Funny thing is, is that the indicator dashboard lights blink when I try using the directional signal whether the headlights are on or off. ALL of the indicator lights on the dashboard work! All of the fuses look ok too. I might pull each one and check conductivity just to check the possibility off the list.
