how many of you gentlemen go to a computer, print out related wiring diagrams ,get out a multi meter and a shop manual and actually read the shop manual, and step thru the indicated testing procedures? check for voltage ohms resistance, loose connections, etc. and have actually used the shop manual, multi meter and printed wiring diagrams ans instructions to isolate and solve a problem on your car?
ITS NOT ALWAYS EASY BUT IT SURE BEATS RANDOM GUESS WORK EVERY DARN TIME

THE DIAGRAM ABOVE HAS THE CORRECT WIRE COLORS FOR THE 1996 CORVETTE
the earlier c4 corvettes had a simplier wire diagram for fans
