Cooling fans not working

[Ahallman]

Cam was installed and car was tuned. Today I drive the car and the temp outside is above 70. I looked down and my temp gauge was in the dead center. It's never been that high. I came home and I never heard my fans running. Popped the hood and nothing. No fans running. I disconnected the harness and tested the fans. Both work high and low. I've swapped relays and took a test light to all related blade style fuses. Everything checked out. I've got to get a volt meter tomorrow. Any body have some advice on this?

So what temp is dead center? I run an obd2 gauge so don’t really look at the oem gauge that much.

If you were moving the fans wouldn’t be needed and you probably have an air pocket trapped.

Check your temp on your DIC display. Check and see if fans turn on with A/C on. Give a little squeeze on those rad hoses. Obviously you've checked your coolant level right? No boil over? As mentioned you may have an air pocket or something didn't get plugged back in during reassembly.

maybe the fans were turned off accidentally in the tune?

I should have ran my obd to my torque 2 but it was more of a panic and shut it down. I had the key in the on position with ac to max and no fans at all.

I could hear the coolant bubbling. Again I shut the car off as quickly as I could and noticed no fans were on with the key in the on position, max ac. I immediately checked fuses and relays. I will be burping the system today. It's too early and everyone's asleep. My car is loud as hell.

I was thinking the same thing. Oddly enough. I went to put it on defrost and accidentally hit the rear defrost and the icon never popped up on my screen. (metra kit) is that something that can be "tuned out" as well?

I paid attention to where the gauge got to this morning and about 1/2 way is where I would expect a stock thermostat to get to. Mine has a 170 thermostat and it gets to about 3/8. The fans won’t kick on unti upper 220’s unless changed in the tune.

This is my only means of transportation. I'm waiting on a ride. My ac fan didn't even kick on. That has me concerned. Before tune I'm pretty sure my fan kicked on around 204.

The tuner could have started with another tune (either stock or an existing modified) that might have had the fans set to different cut on by point. But the not running with ac doesn’t sound right.

Just as a heads up, I did find the problem. 2 actually. I had a relay that was loose and I found a coolant leak from where the oil heater was deleted. Looks like I'll be ordering the upper radiator hose from a 2012 as it's solid and not a 2 piece. Thanks for the help.

Hey, glad you found the problem. Thanks for getting back and letting us know what it was. Good luck with the fix..
