non working air vents/no heat

My husband has a F250 diesel truck. The only vent that works is the one on the floor, and that is because he rigged it up to stay open. Also he has no heat. Since he will wait till last minute I thought I would try to find out what can be done or if anyone knew what the problem is

Thank You

I have a 1999 ford f-250 there is no air coming out of the vents but very little and i live in florida please help

its either not getting enough vaccum to operate the actuator (leak) or there is something wrong with the ac vent door (blend door) or the actuator (mode door actuator) itself

My 1999 F250 4X4 has no heat at all. Checked fuses & relays. Coolant is full. Both heater hoses get hot. Fan & vent selector both work well. When you move heat control from hot to cold it always just blows cold. Need heat - live far up north !

i have a 99 f250 super duty with the 5.4l gas engine. when i got the truck it had slight heating issues such as when you flip the temp knob back to heat it wouldn't always work. after using the ac all summer i can't get the heat to come back on. is this due to a bad knob or something else?

thanks Mike

I have changed the PVH Solenoid, the Vacuum Pump and tested the hub and heater vacuum lines for leaks and there are none to be found. I only have defrost heat UNLESS I put ESOF into 4x4 high then I get floor heat. My feet freeze in 2 wheel drive and are toasty only in 4X4. The vacuum pump continues to run and drawing out the top of the PVH solenoid is that right? If I take the vacuum line off the PVH and plug it, the heating system works fine. Any ideas?

If you want to target autoparts as a whole, that's fine, but it will take a little more time to see the level that you are trying to achieve. If you do something more specific like "Honda auto parts" or "mercedes autoparts" you could have a good customer base once you set up your eBay store!

03 E250 Air blows only default (defrost) Have vacuum help
01/17/11 21:31

2008 Ford F150 - Auto air & heater does not work. No heat or air blow out vents. If it does kick on (which is rare) then the air gets really hot and will not cool down no matter what the temp is set on. The blend door was replaced but did not solve the problem.

The dealership does not know what to do. They basically want us to live with it but we paid for this feature and it can get really cold in NC and we have travel there frequently.

Any help appreciated
