So I could use some help. I am getting no cold air on the driver's side when the a/c is on. So far all I have seen is write ups and videos for the passenger's side. I'm assuming it's the blend door problem. All of the video's say to go through the passenger's side and remove the dash. Would the fact that I'm not getting cold air on the driver's side make any difference?

Also if I keep the a/c running while driving then shut the truck off, then come back in say 5 minutes and start the truck again the drier's side blows cold for a few minutes. I read on another site where owner's have said just adding freon will fix the problem.

Any help or suggestions for this would be much appreciated. Thanks!
