Vacuum loss.
You have 4wd? If so, check the lines to the hubs.

Ya it is, I'll check in the morning thanks! Will I see a crack in the line or one might have poped off?

Both maybe.
You can plug off individual lines and see which one plugged makes the defrost change.

Hey I bet it's your vacuum pump itself. Turn the key on you should hear your pump running. If not it's the pump.
