A/C blows hot in front and cold in back of 1997 Ford Expedition 5.4L

You'll need to replace the temperature blend door actuator, normally you have to pull the panel out to reach it but you might be able to see it if you pull a bunch of stuff from front of panel. Not a very easy job... No there aren't very many good pics of this, this pic was taken from the ford site and was about the best one. The motor will be on the outside but like I said normally the panel has to come out, not a very easy job.

Here is a guide to help you see what you are in for when doing the job.

Actually the mechanics don't make as much as you think they do. If they turn in $600 a week paycheck that would be aboutnormal If it's a dealer the dealer is paying them like $20 per hour flat rate and charging 100 or more. So what ever it takes book wise to replace thepart then that's what they are paid regardless if it takes them days to fix the vehicle. Hope yo get it fixed ok.

Most likely its the blend door motor. This controls the temperature door. Very common. Its located on top of heater box. You can access it by removing glove box.
