I have changed the bulbs in the rear driver side and also the top stop light above the cargo doors. when the car is in drive the driver side rear and front blinker flASH rapidly all appear to be working but the outside driverside brake light is dimmer on the driver side. when the van is in drive and the headlights are turned on the blinkers are not blinking as fast but the interior front cargo light still comes on dimmly when i apply the brakes and when the turn signal is on.
interior dome light comes on when I apply the brakes flashes rapidly when in dR on 2004 Chevrolet Express 2500
