Where can I get a digidoor 1 garage door motor ?

on the rail there should be 2 cylindrical black magnetic read switches with white wires connected to them.
Those are the open and close distance units
sometimes they come loose and move with the vibration of the motor when opening the door

Fixing a garage door is not easy and you will need an expert. Don't waste your effort and take the help of Garage Door Repair Katy TX.

I think the headlight switch sends power to a relay that powers the two motors that open and close the doors. Could be a faulty motor.
You might try an internet search on the sealant or check with a local body shop for tips.

Instructions

1. • 1 Turn off the engine of the car and press and hold buttons 1 and 3 on the Jeep's transmitter for 20 seconds to erase previous codes. Release them when the display reads "Channels Cleared."
     
   • 2 Hold your garage-door remote 1 to 3 inches from the Jeep transmitter.
     
   • 3 Press and hold the open button on your handheld remote and simultaneously press the button you wish to program on the Jeep's transmitter. For example, if you want button 2 to be the one you use to open your garage door, press button 2 while pressing the open button the remote.
     
   • 4 Release the button once you hear a beep and the display reads "Trained."
     
   • 5 Press the "smart" button on your garage door motor. This button is usually located on the back or side of the motor near the antenna wire and light lens.
     
   • 6 Return to your vehicle and press and hold the programmed button in your Jeep for 2 seconds. Release and press and hold the button for another 2 seconds to complete the programming sequence. You will now be able to use the vehicle's transmitter to open your garage door.
     

$4000 for a cam??? Get real. They aren't that hard to replace and don't cost that much. Advise: 1. Find a New shop to do the work. 2. Get the Haynes Manual on your vehicle and do it your self. This shop you took it to screwed up and they are giving you a price to blow you out the door because they know they screwed up. If they did the job correctly they checked the tolerances and scoped and turned the cam which would have prevented this from happening. But that is way too high for a cam. If you talking Crank then they may have a halfway correct price but since that can actually be replaced in that vehicle without pulling the motor I would find a new shop. New crank should run around $200-$300 depending on the type your installing. Another $200 to $300 for labor and your out the door. Since they just replaced all the seals and should have turned the crank and replaced the Connecting and Main bearings those should not be an issue. I hate to see people taken advantage of, you can replace this cam or crank yourself relatively cheap compared to what they are wanting. That shop is trying to take you to the cleaners because if there was any problem identified while they were doing the seals they should have told you. I would do a real hard check of that motor and double check their work because it sounds like you paid them to re-seal a motor and what they did was take it out, steam clean it and put it back in replacing only the valve cover gaskets if they had to, very old shady shop trick like putting saw dust in the transmission.

I hope this helps.

Programming the HomeLink Transmitter
Do not use the HomeLink Transmitter with any garage
door opener that does not have the stop and reverse
feature. This includes any garage door opener model
manufactured before April 1, 1982.
Be sure that people and objects are clear of the garage
door you are programming.
It is recommended that a new battery be installed in
your hand-held transmitter for quicker and more
accurate transmission of the radio frequency.
Your vehicle's engine should be turned off while
programming the transmitter. Follow these steps to
program up to three channels:
1. Decide which one of the three channels (one of the
HomeLink buttons) you want to program.
2. Press and hold the desired button on HomeLink
through Step 3.
3. When the HomeLink indicator light begins to blink
slowly (this may take up to 30 seconds), hold the
hand-held transmitter about 1 to 3 inches (3 to 8 cm)
away from HomeLink and then press and hold the
transmit button on the hand-held transmitter.
Continue to hold both buttons until the indicator
light on HomeLink begins to flash rapidly (this may
take up to 90 seconds).
If you have trouble programming HomeLink, make
sure that you have followed the directions exactly as
described and that the battery in the hand-held
transmitter is not weak. If you still cannot program it,
move the hand-held transmitter to the left or right or
forward or backward or flip it upside down. HomeLink
may not work with older garage door openers that do
not meet current Federal Consumer Safety Standards.
If you cannot program the transmitter after repeated
attempts, refer to "Training a Garage Door Opener with
Rolling Codes" later in this section or contact the
manufacturer of HomeLink at 1-800-355-3515,
or on the internet at www.homelink.com.
Be sure to keep the original hand-held transmitter in
case you need to erase and reprogram HomeLink.


Training a Garage Door Opener with a
"Rolling Code" Feature (If Equipped)
If you have not previously programmed the hand-held
transmitter to HomeLink, see "Programming the
HomeLink Transmitter" listed previously. If you have
completed this programming already, you now need to
train the garage door opener motor head unit to
recognize HomeLink.
1. Find the "Learn" or "Smartbutton" on the garage
door opener motor head unit. The exact location and
color will vary by garage door opener brand. If you
have difficulty finding the Learn or Smart button,
refer to your garage door opener owner's manual or
contact the manufacturer of HomeLink at
1-800-355-3515, or on the internet at
www.homelink.com.
Because of the steps involved, it may be helpful
to have another person assist in programming
the transmitter.
2. Press the Learn or Smart button on the garage
door opener motor head unit. An indicator light will
begin to flash when the motor head unit enters the
training mode.
Following this step, you have 30 seconds to
start Step 3.
3. Return to HomeLink in your vehicle and firmly
press and release the programmed HomeLink button
three times.
The rolling-code garage door opener should now
recognize HomeLink. You may either use HomeLink
or the hand-held transmitter to open the garage door.
If after following these instructions, you still have
problems training the garage door opener, contact the
manufacturer of HomeLink at 1-800-355-3515,
or on the internet at www.homelink.com.

First remove the door panel, peel down the water barier, you will see three star screws remove these, then remove the window motor, take themotor apart, replace the plastic plugs with ball bearings, repact the motor, then remove the rivits holding in the winidow regularot and the window glass. To do this you need /14 punch, punch out the rivits, then using 1/4 drill drill out the aluminum plugs, replace these with 1/4 boltd and lock washers. Replace the window but do not over tighten the window or it will go up slow. You can purchase the regulators on line much cheaper than purchasing them from a shop. On Line around $18-30. At an auto shop $60-70. Hope this is helpful.

there is a great website that has the instruction go here and download the instructions http://www.homelink.com/programming/programming.taf
If there is anything else I can help you with let me know

1. Position vehicle within 10 feet of garage door- engine off and battery on.

2. Press/hold 2 outside buttons of Homelink transceiver until red indicator starts flashing rapidly, then release button. This should take about 20 seconds. This erases any previously learned codes.

3. Press/hold remote control and press/hold button of Homelink transceiver simultaneously. Slowly move remote control from 5" away to 1" away from Homelink transceiver. Release both buttons after red indicator starts blinking rapidly. This should take about 5 seconds. I discovered that the Homelink in my TL is a bit faulty because it took much longer to accomplish this than when programming the Homelink in my MDX. My TL's Homelink may "unlearn" it's code in the future and the needed proximity of the TL to the garage door may be much closer than desired until I get the Homelink fixed.

4. Press training button on garage door opener unit until the indicator lights illuminates- this should be immediate.

5. Within 30 seconds press/hold the Homelink button for 2-3 seconds until the red indicator starts flashing rapidly. Repeat a second time. It should now be programmed. Check it by pressing the programmed button on the Homelink receiver.

6. When programming more than 1 garage door opener unit, disconnect power from unit before programming more units. By not doing this the programmed unit could conflict with the unprogrammed units commands.

Problems:

1. The Battery in the garage door remote may be too weak to program Homelink. However, the battery may be strong enough to operate the garage door. One of my remote controls had a weak battery- my system was installed today, fresh out of the box. I had to use the second remote control for the programming of Homelink on my 2 vehicles.

2. Antenna on the garage door opener unit must be hanging down, fully extended.
