1998 Chevrolet Astro Question: my 98 astro keeps blowing the signal-b/u fuse anyone else have this problem ?

there are no codes for blown fuses. it has a short somewhere in the system and needs to be tracked down. i suggest a good electrical shop to help you out as there are so many possibilities that could cause this.

thanks roy we tested for shorts and got it narrowed down to between the fuse box and the blinker switch

you need to identify the color wire from the fuse boxto the switch. if it is ok, disconnect the switch and see if the fuse holds.
