think logically,your cars symptom's can help isolate the problems source/cause
if the fans work when tested individually,
but they fail to come on,when they should, its likely a temp.
sensor or a relay related issue.
these are generally not difficult to test or just replace.
but it can be rather frustrating if your not familiar with a logical testing,
and isolation method of finding the defective components(s)
PULL TROUBLE CODES CHECK FUSES
this is one of the more constantly recurring issues,:( with the c4 corvettes
these corvettes are now 25 plus years old in most cases,
the relays and sensors are going to fail randomly if not replaced.
you'll need to get good at isolate and testing procedures,
and having the correct year shop manual is almost mandatory.
use of a shop manual and multi meter can be very helpful,
its just a simple process of testing sensors ,
fuses and fuel delivery voltage and circuit resistance

without testing you simply guessing
never guess, deal in verified FACTS!

guessing is a waste of time
think logically, isolate and test

yes IM aware some guys would rather dig out their eye with a red hot fork than to read links,
but if you take the time to actually research the problem and isolate and test you,ll soon find the answers
well the first thing you do is pull trouble codes
and it would help if you purchased a shop manual.:D
