I'm having a very similar issue. My AC and heat work fine, but I can't switch from vent to floor to defog. It sort of blows from all three at once. I'm told I have a bad "defroster door actuator motor". But I wonder if I have a vacuum leak. I do know two hoses that run over to the brake booster are cracked (but no brake issues). Could I be losing vacuum and that affect my dash/defog/floor selector? Thanks for your help, and the video!
Thank You , you nailed it. Ez fix for a problem I’ve chased for a couple of brutal summers on my son’s truck !!
Wow thanks you helped me get my ac blowing through vents! Bravo 🎉😂😊
At least on my 99 if you have a 4x4 it’s not a ball it’s like tube shaped
