double check that the jumper cables did not loosen your battery ends.

Need some sort of antifreeze in the transmission by the sound of ,think its just to cold ,either put a small parrifin heater under the engine or some sort of antifreeze ,evan diesel will wax at these sort of temperatures.But i seem to remember someone saying that in siberia in the WW2 era the russians kept their tanks running by putting petrol in with the oil to stop it freezing ,thats how they defeated the germans because they didnt know about this and left engines running using precious fuel.another useless fact i learned from someone,but 20 yrs after a german here in spain told me the same story ?? Who knows

If it has a trailer harness ,check this harness,you may need to replace it.

i hate to ask you this,so don't be offended,
but did you remove both protective coverings from each injector?and did it run before you changed them?and why did you change them?

not too bad... remove the front wheels ad go thru the wheel wells, I usually use a cherry picker to support the engine..

rip it out and put a manual gearbox in .

if you are referring to the check engine light... disconnect the negative terminal on the battery for about two minutes then reconnect this should take care of the light.

the oil sending unit is in the rear of the motor center right as you face the motor.You almost have to climb up on the motor to see it because it is down on the block.If you remember where the distributor used to be in the rear.The sending unit is just to the right as you face the motor.Good luck.

The little snow flake you speak of,is what we used to call max air.This actually closes the vent to the out side,and recirculates the inside air.This is supposed to make it colder.The problem with the air system,that you are having is,the actuator motor for the directional door in the vent box,and the temp door,This would be a good job,all these door actuator motors are hard to get to.If the ac line going into the firewall is cold while this is happening,then it is the actuator motors that have gone bad.This would be the large ac line,low side,the one going into the cab,from the engine compartment.If the ac line(large,low side)is sweating,and it is not cold,you have a problem.Check it and see.When this happens,it usally means that there is air in the ac system.If the ac was evacuated and charged with a recovery machine,this was the problem.The machine is faulty,and is not recharging with 134a freon,but mostly air.This happens sometimes when the straw in the freon tank has fell off in the tank,or the valves in the recovery tank are not shuting off all the way.Air condition is my certification,I know ac on automotive,And I have had this problem before,numerous times.I hope this has help somewhat,if so,please let us know,thank you.

You have a 6.6 diesel correct? check for leaks between the air cleaner and the turbo. If you can't find any you may have a sticking egr valve. If you just want to clear the code, try disconnecting the battery for a few minutes.

The dealership has to program it. There is no unlock code. Also, these radios are very specific in these years and trucks. Looks mean nothing, only part numbers are important.

I would check the brake switch, located above the brake pedal.  It's not common, but they do go bad occasionally.

it is located in the wire harness that runs along the column. You have to take off the panels around it to get at it. Some earlier models had a fusible link that was not replaceable and you had to buy the new harness (which came with an actual inline fuse). Not sure which one yours is.

This is because your brake light switch has gone out. There are two sides to the switch one goes to the two main lights and the second goes to the third light. This is a common problem but is an easy and inexpensive part to replace. It is located on the brake pedal and can be changed in just a few minutes. Good luck and thanks for using FixYa!

Your brake light switch has gone out. It is located on the brake pedal and is a very easy cheap fix. When it goes out, it doesn't send the signal to the bulbs to turn on. The bulbs are still good they just don't know they need to work. Replace that and you will be good to go. I'm assuming USAF is for Air Force. If so, thank you so much for serving our country! Let me know if you have any other questions. Thanks, Keith.

then your fuel filter is clogged or your gas guage is broken and she's bone dry

The vents are controlled by and electric actuator. The actuator when it starts to go bad will lose it's base and not know where the gears are to have the vent door open or closed and soon the gears will over run and jam to the open or close. Sorry about the bad news. Best thing to do is turn your a/c system off and everything to the off position before turning the engine off, so when the truck is restarted the system is already in the default and not have to reset it self to know where that actuators are. Good luck.
