Hey all, new here and first time posting. I recently purchased a 2008 H3 Alpha and noticed whenever the A/C is engaged it will blow air, but the moment I switch it to the max fan setting of 4, it cuts off entirely. Any ideas? I checked all fuses on the truck when I first got her. I took her in for the recall service as well. Has anyone else seen this issue or know where I could begin narrowing down what the issue could be? Thanks!

 

Has it had the HVAC recall performed?

Search out the HVAC resistor threads as well.
