96 C4 Cruise Not working
The Cruise on my 96 never worked when I purchased it and I need to get
this thing fixed. I turn the switch on but nothing, is there a dash light that should come on wether you are driving or not? I checked the fuse and it was blown, replaced it and still nothing. I'm thinking it may be the module but I cannot locate it(my first vette). Any ideas would be appreciated. I've read the threads about the vacum lines and didn't even bother to check them yet. Thanks, Dave |

Some simple things to check, which you have already started, if these are ok than you may need a professional to fix it. Check the fuse, the power, and continuity at the vacuum pod switch and the 2 part brake light switch behind the brake pedal. Get a friend with a similar model to compare it's operation to yours. My guess would be vacuum. Last but not the least important, check to see if the CHMSL (center high mounted stop light, third brake lights) are working. Seems the cruise circuit uses the CHMSL bulbs for a ground or at least part of the circuit, if one is out the cruise control won't engage in some cases. -- Dad 05 C6 Silver/Red 6spd Z51 72 Shark Black/Black/4spd 64 Red/red/white top/4spd |

The C5 and 6 has a message in the DIC that says "Cruise set XXX" and then goes out. |

I had the same problem and it was just the vacuum line. My troubleshooting training has always been to check the cheapest, easiest thing first. Rob |
