You will need a volt Volt-Ohm (VOM) reader to fix this problem.
This doesn't rquire sound technical knowledge for this but you should be good at following some instructions.
This could be the effect of a number of problems. Here's a list of things to check and details on how to do it.

• Fuse could be bad -- Check the fuse for a break inside. If it’s bad, replace it with an identical fuse.
• Temperature switch could be bad -- Use VOM to check the switch. Set VOM to RX1, remove leads and touch the probes to the switch's terminals. The reading should be zero or infinity. Turn the switch, and the reading should change from zero to infinity or infinity to zero. If not, the switch is bad.
• Thermostat could be bad -- Set the VOM to RX1, take a lead off one of the two outside terminals and press the probes to the two outside terminals. There should be a reading of zero. If not, it's bad.
• Heating coils may be bad -- Set the VOM to RX1 and remove the leads from the coil. Press the probes to the terminals. If the reading is zero, the coil is bad.
• Timer could be bad -- Disconnect the leads from the motor. Set the VOM to RX100. Clip the probes onto the leads. If the reading is infinity, the timer motor is bad.

a lot of 4wd you have to back up for a few feet to disengage the hubs after you tourn them back to 2wd

If you have a Chraftsman/Liftmaster:
1.Check to see if the door is running correctly.
A. Run the door down and pull the emergency release. See if the door will run easily by itself.
1. If it runs hard by hand try lubricating the rollers and hinges with silicone spray or some form of lubricant (not WD 40)
2. If the door is heavy and falls back to the ground, you probably have a spring issue (either broken or needs more tension) in this case call a professional door repair company in your area.
B. If the door runs fine then check the up and down force on your operator (the box that hangs from the ceiling and reads Craftsman). If the light(s) on your operator go from front and/or back, the force adjustment screw is on the back of the operator. If the lights are on the sides of the operator then the force adjustment screw is on the right side (looking from the back of the operator and facing the garage door). Turn the light blue adjustment screw with the up arrow to a higher number.
C. If this does not solve your problem the top bushing could be going out of your operator. Open the case and see if a lot of black filings are on the top of the big gear. If so the gear assy. will have to be replaced part # 41C4220A

Check your down limit switch and even your up one too almost sounds like one is stuck one way or the other.

Timer may need to be replaced. You can test it with an ohmmeter or test light.
You can do the same with the push button. If you have more problems, then the main control could be faulty
