97 Camaro z28 Cruise Control Inop. Any suggestion i've looked at all the fuses no avail. Any Suggestions? Only thing I can think of as a posiblilty is the switch.

 

Has it ever worked while you owned the car or is this loss of CC something new?

 

doesnt the cc go out if one of the brake lights are out? i thought i read that somewhere.

 

Doesnt a brake light being out also trip the "abs inop" light? Reason i ask is because my light is on and my cc is no good either... maybe i need to check that

 

ya im pretty sure the third brake light will trip the abs inop but i swear i remember someone saying it will shut down the cc too

 

yep i have heard the same thing, from pete i think. i dont know because my center light has never went out. lol now it will.

 

It has worked before but now it doesn't. I'm at a loss

 

my cc in the first 93 quit working and it was the switch in the blinker handle. picked up a new one and worked fine. it would work then not then work etc. one day it wouldnt work anymore.

 

here is wiring for 93 you have a body control module in there, here is wiring for it http://shbox.com/1/bcm_1996.jpg

 

I know for a fact the third brake light being out will cause an "ABS INOP" light on the dash and loss of cruise control on the '94 Z28s. However, GM rewired the system in '96 or '97 IIRC to fix this issue.

The short explanation I found somewhere online was that the wheel speed sensor on the rear axle gets its power in series through the third brake light. So if the third brake light is burnt out, then no voltage can get to the speed sensor, and therefore no ABS or CC. Also, if you replace the standard bulbs with LEDs, then you need to also add an automotive relay into the wiring to get everything to work again (though I cannot remember the reason why).

I know this because when I bought mine a few years ago, I had the "ABS INOP" light and no cruise control and my third brake lights were burnt out. Once I fixed the third brake lights, my CC started working and the "ABS INOP" light went out.

I would suspect that the third brake light being out would affect a '93 in similar manner.
