2009 Ford Ranger blows only cold air in max a/c mode regardless of where the temp control is set. It blows only hot air in all other modes regardless of where the temp control is set. ---

Probably have a mode door issue and it is not moving correctly . ---

So what is your question? Why is it doing this? Where should I take it to get it fixed? How do I fix it myself? Will one of you guys come to my house and fix it? Which one? ---

More than likely there’s a problem with the HVAC control module. ![image](https://global.discourse-cdn.com/cartalk/original/3X/9/5/95865c87d7b9ad8e7d5bb28a21fb12e4f2bb232f.jpeg) Tester ---

The other 2 posters have 2 good suggestions. Find the mode door and how it is actuated… a push pull cable or electric actuator. It is under the dash and may need replacing as might the HVAC control module. ---

Looks like it uses vacuum distribution from the mode control to shuffle things around. This could mean a leak in a vacuum line, vacuum canister, or the control panel itself. My guess would be the control panel. If it’s anything like Ford’s EATC units there may be a number of irritating tiny O-rings in there; any of which are prone to leaks. The EATC units are rebuildable. I do not know if the manual control is. Likely not. To narrow it down may involve a vacuum tester, smoke machine, and a Helms manual. Weighing that cost against an educated guess it might be faster and cheaper to guess at the control unit. I do not know the limits of your mechanical expertise so it’s difficult to say plow ahead and start following vacuum lines and so on. ---

My gut feeling was that the controls are electronic only. That’s why I pulled up one for sale on eBay. It shows the color coded vacuum lines have been snipped off (lower left) along with the other wiring. Several others I pulled up also showed vacuum nipples on the ones without connectors. I’ve never had occasion to tear into a 2009 Ranger so I can’t speak definitely. ![image](https://global.discourse-cdn.com/cartalk/original/3X/6/a/6aa3d2a5b47c84414f7bc1f8bb1334b346267c1e.jpeg) ---

After some investigation, it appears to be a blend door problem. This is the hot/cold control. Either the actuator or the control panel resistor. ---

Had 1 carn no ac at low speed, but fine on the highway, turned out the fan was not actually working, blower resister.
