Originally my passenger door on my 2003 Chevy Trailblazer EXT would not always unlock with the FOB. Was an intermittent problem. Then last friday my driver and passeenger doors would not lock or unlock with the FOB. But worked fine over the weekend. Happened again on Tuesday. Also noticed left blinker indicator on dash and blinkers were blinking about twice as fast as normal. Right blinkers were normal. Anyone have any advice?

hi usurally when that happens that means you have a bad bulb or bad wiring.

Which is it, 98 Eclipse, or 06 Impala? Either way, your door lock actuator is stuck in the locked position either electrically or mechaically. The way to check this is to remove the door panel and unplug the actuator. If door lock can now be moved then you have an electrical problem (faulty door lock switch or faulty door lock module). If you still cannot unlock door then actuator is mechanically bad and must be replace (usually the case)
