Cool Fan 1 issue
I have a 2008 SS/TC, with a ZZP tune. Currently I have noticed increased coolant temperatures upwards of 229f. I opened to hood only to see cool fan 2 (passenger side)working, cool fan 1 was not. To my knowledge at at temp as high as 229f both fans should definitely be on. Here are the steps I have taken to troubleshoot cool fan 1 not working:
1. Checked fuse, not blown, tried another 30A fuse anyways
2. Checked relay, verified it worked after applying resistance, tried another relay
3. Applied 12 volts to the fan, it turned on.
4. Checked cap on coolant tank
5. Reset ECU
6. Turned AC on and off to see if anything changed
Im out of ideas, does anyone else know what I should try?

Correct... You could try swapping the relays or jumper 30-87 to check it.
Just remember, when you find 30 and 87 0n the relay, your looking at it upside down. It is usually the bottom left and top right opening.

Anyone know where I can get another one of these connectors? After visually inspecting the underside of the fuse box the ground wire coming out of one of the fan relays is burnt.
