Have a 2003 Ford F-150 air condition compressor turns on once in awhile and then doesn't turn on have voltage to low pressure switch . And jumped out the low pressure switch it doesn't turn on at all no voltage change out the low pressure and high pressure switches relays fine and have good fuse so could it be switch on the dashboard bad. Also never added Freon into the system but you need to compressor running to add freon to the system correct

2003 Ford F-150 Crew cab 5.4L Headlights stopped working replaced the combo switch worked for a little and now does not. I can get headlights to work on High Beam ONLY when I manually hold(PULL) the switch back. Running lights are always on but no Headlights. Any help would be appreciated :)
How long have you had this problem? Months
Set still it comes out the vent but driving down road it comes out the defrost.
Especially noticeable on the freeway. Truck drives normally until you lift your foot off the accelerator to slow down (like in traffic). When you accelerate again, you can feel the truck missing or slightly hesitating.
I check Freon that's good. I have the A/C heater auto climate control unit.
I am not sure if I am posting in correct place. My husband has a 2003 Ford F-150 with a 4.6 L V8 that has many problems. 1. The Service Engine light comes on. 2. The engine starts missing. 3. The Temperature Gauge goes to hot. 4. Oil light comes on. 5. He put a tester on it and it reads that the #1 Cylinder Misfire Code comes up.
What he has repaired so far: 1. Replaced the PCM. 2. Replaced all plugs & all coils. 3. Checked all fuses.
It is still doing this. What is causing this problem?
