Hello, on my 87 camaro only the driver side cooling fan comes on when car is hot and neither come on with the a/c, i put a wire in pins a and b on the obd1 to put the car in diag mode and only the driver side fan comes on, when i tested this with the car hot the drivers side fan came on but after about 20-40 seconds i heard a click and the passenger side fan came on but the driver side fan went off. when i tested this a second time only the driver side fan came on and stayed on. i checked both relays by the battery for the fans and they both work, i checked this by swapping the relay for the fan that wont come on with the fan that will come on and the driver side fan still worked. i checked the a/c relay, the one that has a green wire with a white stripe on the drive side firewall, and that one is not clicking when i turn the a/c on. im kinda stuck on what to do next to get the fan to come on. any ideas anyone?
