Woohoo!
Thanks, doods. Before I read this, I had an inkling it might have been ABS related. I considered removing both ABS fuses under the hood to check, but I'm glad I read this first to save me the "trouble".
Fact: I ran my 1998 Tahoe w/ the ABS fuse removed for three years, to avoid replacing the unit. Besides, I like to be in control.I'll be different w/ this car!
