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.

Do you
have the same problem?

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!
