Picked up a high mileage 2005 1500 a couple of months ago. A/C wasn't very cold. Just figured it needed a little freon and never got around to it. Now with cooler weather, we tried to get some heat the other day. Very little heat. Google around and assume a blend door issue.

I don't want to spend days fixing this. I've found a shortcut fix from HeaterTreater for fixing the doors. Anyone familiar with this deal? Any other suggestions? I'm going to get under the dash and try to verify the cause this week.
