Hey, btw your GA has a 3.4
So your fan as in the heater blower is not working?
Does it work on any settings?
Years ago they were under the hood where they usually got wet and when they failed they usually made all sorts of noise. But yours in on the pass.side under the dash. Which they still do get wet when your HVAC drain becomes clogged.
Check the fuses and relays first.
Drivers side IPC/HVAC Batt
Pass.side HVAC Blower motor
Under the hood fusebox, #13 mini relay Hvac blower
maybe #53 Fuse.
If those are good then pull the kick panel off on the pass.side floor. Some 5.5mm(or 7mm) screws hold it on.
Three screws hold on the blower motor.
Be sure and check all your plug connectors for corrosion.
As this can happen and make your blower not work.
If your blower works on 3-5 settings then its your resistor which is behind the blower. Same screws, 2 of them, a real pain to get to laying on your head.
If you need anything else just ask!
