Check the vacuum line from the engine intake manifold. You can identify it as a small diameter plastic hose that goes from the engine to the firewall on the left side of the firewall. Is it connected to the engine? Is the hose at the connection cracked or otherwise leaking? If the hose is OK, it may be the switch at the control unit. If you can pull the vacuum connector from the control panel, check to see if there is vacuum on the same hose from the engine while the engine is running. If you have more questions, please reply.

I have a 2002 Ford Econline E350 that the front air comes out only out of the windshield area, no air out of face/feet area. Already replaced the Blending Door Actuator, please help! :)


Go directly towards a vacuum leak . The vacuum reservoir is notorious for going bad in the these vans , unfortunately you have to pull the heater box to repair it which takes numerous hours. Hopefully it is just a vacuum leak that's accessible. If its a diesel I would first check the vacuum pump , if its gas then start by checking the small vacuum line under the hood along the cowl on the right rear of the engine compartment. Pull apart one of the tee fittings and check for vacuum with the engine running . Then check inside the truck pass side under dash for a bunch of vacuum hoses . Got vacuum?

99 ford f150 heat works fine but after 5 minutes of driving goes ice cold !! Changes heater core checked hoses checked switch checked blend doors flushed it twice everything!! Any advice?


Could possibly be a vacuum leak. The blend door actuator controls are usually ran off of vacuum. It is possible that once the engine warms up, even though you have it to heat, the loss of vacuum will cause the blend door to switch positions.

A/C is blowing out of the floor vent instead of the dash vents


The vacuum motor in the blend door is not working right. May have to replace the blend door motor or check for vacuum hoses working themselves loose from the actuator.
