Yes I have a 2000 Blazer and all of a sudden my left blinker light blinks so fast and the right blinker is OK . I tried to take out the left rear bulb but the front is still blinking crazy. Do I need to change all bulbs? Thanks for any and all help.

Don't change all of the bulbs until you have checked all the bulbs.
Your problem could be the left front bulb, but you need to check.
You could also have a poor connection inside the lamp socket. Inspect the socket carefully.

Thank you. I got to looking around and on my back left light it had about 2 inches of water and the bulb was coroded. I drained the water and replaced the bulb and put some stuff to fix the leak.

Thanks again Terry

It's best, if you can, to apply dielectric grease to the base of the bulb.
