Chevrolet Camaro stopped using back windshield vents in order to reduce manufacturing costs of the newer model of cars. They had no significant function other than aesthetic.
A plugged up fuel filter.
1974 was the last model year for points in a Chevrolet.
There is also a flasher unit that makes them flash, try replacing that unit.
Chevrolet stoped making camaros in 2002. They just released the new 2010 camaro.
They haven't, it's still being produced.
You can stop using it whenever you want.
#1: check the fuses!!!! you could save yourself a big headache if it's just a blown fuseCheck the bulbs if they are good check the grounds for the lights.
