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

Along with the 'vette, a Factory Service Manual (fsm, alias "Helm
manual") is a good idea. Check eBay or order from <www.helminc.com>.

C4 cruise control doesn't resemble that in other GM cars. Early C4s had
it integrated into the dash display along with the signals to and from
the engine control module -- '96 is probably somewhat different. The
'96 FSM will give you all the circuitry, troubleshooting 'trees' and
test measurements. Even if you don't do the work yourself, the info
will help your mechanic fix the problem.

Here's one for less than $ 60 -- a bargain: < http://cgi.ebay.com/ebaymotors/1996-...spagenameZWDVW

This is a complex system that requires an electrical schematics to
diagnose correctly. 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.

OK thanks but is there a light of some sort that should come on and if
there is will it come on when the switch is in the on position or does
the vehicle have to be moving for the light to come on?

I have no idea, it has been 10 years since I've driven a C4. The C5
and 6 has a message in the DIC that says "Cruise set XXX" and then
goes out.

no, there is no light or any other indication that it is in operation
besides the gas pedal going up and down.

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.
