For some apparent reason my blazer has started to blow out the blinker fuse when I turn on the blinker. I went through and checked all the wiring and couldn't find any problems. I also lost the fuse that alarms you when you have left your lights on. I managed to get them to work tonight, but they have a funny blink to them, not normal. Blinking kind of fast. Has anybody ran into this before? It's an 89.
