FAN WONT ENGAGE

2008 GMC Acadia • 6 cylinder FWD Automatic • 52,000 miles

The fan wont come on on our gmc 2008 acadia even though it shows the bars lit up as if it is on. The fuses are all good and I can't seem to find a relay any where for the fan.

There's 3- relays in the underhood fuse block above right front wheelwell-power the fan motor direct from the battery if it comes on-check the relays, coolant temperature sensor and computer

I am talking about the fan inside the car for your heater and a/c to blow inside the car. Maybe you call it a blower instead of a fan. Is there a relay for this fan/blower somewhere?

There's no relay involved or blower motor resistor

Check the HVAC blower fuse if okay-the problem is coming from the blower control module or the HVAC contol module-have it checked

Hey svjorn,

I'm having the same problem you had. The blowers won't seem to turn on. I was wondering what you did to fix it.

Thanks for the help!
