Three problems related to exterior lighting have been reported for the 2000 Chevrolet Blazer. The most recently reported issues are listed below.
My customer complained of a transmission failure involving, but not limited to a dtc p0785. I asked my customer if the involved vehicle (2000 Chevrolet Blazer) had any dealer or after market accessories installed, customer adamantly replied: no, "bone stock gm. " my customer was not aware that the involved vehicle had a theft deterrent system, manufactured by "karr" and distributed by audiovox with installers nationwide. I have been actively involved with gm dealerships for over forty years and possess a wealth of experience in parts and service experience. I removed the suspect security system and repaired the damaged wiring which resulted in the improper installation. In the past week I have been confronted with four customer complaints which resulted from security systems, aftermarket radios and including aftermarket headlamps. These aftermarket components are the direct cause of system failures involving engine management systems, lights, and numerous electrical failures. I sincerely request immediate and thorough investigation which I remain confident will result in massive recalls of these inferior products.
My blinkers started blinking real fast and I couldn't figure out why. I asked my brother and he told me I had a light out somewhere, so he helped me locate it. It was my blinker on the driver side back. I replaced it and a few months later it happened again. I replaced it again. All this happened in 2013. In the summer of 2014 it happened again with the same light. I replaced it again. I was watching good morning America this morning and seen where they were investigating safe cars at used car dealers. It gave a web site to look and see if your vehicle has any recalls. I looked and it showed mine had 4. I called the number it gave and the lady told me mine had none with the VIN # I gave her. Why then am I having problems with this one light?.
Interior and exterior lights flicker on and off during normal operation at night. Dealership has examined vehicle, and has been unable to identify the problem. Please provide any additional information / documentation.
