Q: No turn signals, brake light or instrument panel lights.

asked by on

I found that my driver side rear directional signal and brake light were not working. The bulb connector was corroded. Bought a new connector, bulb and fuse and installed them. Everything worked fine. Today after driving a short distance(less than a mile) I returned to the car and had no turn signals or brake lights or emergency flasher or light for the dashboard speedometer display. Got back home and checked all connections, nothing appeared to be wrong. Can you offer any help?

My car has 193000 miles.
My car has an automatic transmission.
