I have a 91 hatch and my friend told me the other night that my rear parking lights aren't working but the brake lights do work...I know that the bulbs are dual filaments and they seem to be intact...I checked all the fuses I believe...what else could it be? Please help a fellow HT'r out...thanks!

 

check for voltage, maybe a fucked up wire somwhere

 

but check all those fuses again just to be sure. Its the easiest thing and the most common. You could spend all day troubleshooting it looking for broken wires and such.. then find that its the fuse you half-assed checked. check again
