have a 03 PT Cruiser/2.4 turbo. Headlights, interior lights, and dash lights all flicker. Took to local dealer, replaced generator, did not fix. Replaced pcm, did not fix. dealer service tech said this is nomal condition and that several pt's on lot did the same. I have replaced battery, previous battery was leaking, and cleaned cables. Car has 63,000+ miles. Any suggestions?
