I have a 2001 Chevy Blazer, we have replaced all bulbs and checked/replaced fuses. My left signal blinking fast and my right signal not blinking at all and my back lights are staying illuminated. Do you have any ideas on what we can check next???
Check the light bulbs them self for being the specified number ( should be listed in the owners manual )
( ex. a technician will install a 3057 instead of a 2057 bulb) these bulbs are different, and so is a 3157. they all look the same but don’t work the same. Make sure to check all of them in the rear for this. This occurrence is more common than you think. Feel free to check out some of the other resources on the website as there may be some helpful information available.
