Hi, I have a 1978 - 924 with a/c, (it has 2 fans.) The driver side fan will kick on when the temperature starts to rise too high, but the regular fan is never on, any suggestions?
Thank you,
Gary

You have to look for the wiring diagram for your specific year, there are at least two versions, early and late.
My 1980 924 turbo with AC had the same problem, also my AC wasnt working.
The problem was misplaced relays and the wrong relays being used.

So first of all check that you have the right relays installed in the right slots.
Then check the fan itself by feeding it 12V to see if it is operational.

I went through the relays and found one slot empty, that not the problem though. I will try the 12v to the motor to see if that may be the problem.
Thank you.
