    Default 02 blazer blinkers blink fast

    I have an 02 blazer and when I signal it blinks fast like I have a light out. But all my lights are good. I replaced the flasher and it still does it. Also the console "abs" and "brake" lights are on almost all the time. I don't think the 2 are related but need to fix them both.

    they probably are related, you most likely have a bad relay or a shorted/damaged wire, most likely though the relay, common issue. cheap fix.

    Right now its all stock. I want to do LEDs but wanted to get everything right before I make any changes. Another thing the break and abs lights go of if I leave the parking break on over night. but they come back on with a few miles down the road. Periodically they go off while driving but usually come on again with in a few miles. I will look in to the relays. Does any on know of a way to test relays without replacing them.

    Could also be a bad ground somewhere. I had this problem back in the day, ended up being a bad ground. Everytime I hooked up a trailer it would slow to normal speed. You can probably take it to auto parts store and hook there computer up to your obd port and read any codes. Might be a bad speed sensor.
