Shade Replacement - Motorized Windshield Shade (with 2nd Generation Motors 4280P and 4270P)

This manual will guide you through the process of replacing a motorized DRS (Double Roller) Windshield Shade. In here we explain how to remove and replace the whole shade assembly. If you need instructions on how to replace the motor inside the shade only, refer to QRG #17.

For instruction on how to access the shade assembly behind the valence, contact your coach manufacturer.

In here we explain how to remove the whole shade assembly.

1. Disconnect the wire cables of the shades from the vehicle wiring

   Before you remove the shade from the ceiling, you need to disconnect the power cables of the shade from the coach wiring. With 2nd generation motors, there is a Molex connector that you need to disconnect the cable from this connector. Do not cut the wires!
   To disconnect, you need to press the lug on the Molex connector then pull the connector to separate. (Do NOT pull from wires. Hold the body of Molex connector and pull).
   On 4280P this connector located on the cable, 3 inches away from head of motor, but on 4270P this connector located right on the head of Motor.

   Note:
   It is a good idea at this point that you verify whether it is indeed a motor problem that makes your shade inoperable as it could also be a wiring problem in the vehicle; in such case you would find out that your shade problem still persists even after having replaced the motor. To verify this, remove the cable that supplied with new motor and use this cable as a tool. Connect this cable to the motor directly, and on the other side of cable connect the green and blue wires to a battery; if the shade starts moving in one direction and when you swap polarity of green and blue wire, it moves in the opposite direction then you know that there is nothing wrong with the motor and the root cause is a problem from the vehicle wiring. Please note that if there is a 3rd (red) wire, you do not need to connect it to anything for this test. Keep this extra cable that supplied with new motor, as a test tool for your future tests.

2. Removing the Shade Assembly

   Now that you have disconnected all the wires, you are ready to remove the whole shade assembly. The windshield shade mounts on the ceiling of the coach. The heavy-duty top mounting rail has 4 to 6 mounting brackets, each with 2 screws. Due to the size and weight of this shade assembly, this job requires two people. On the following pictures you can see how the shade assembly is installed to the ceiling.
   
   To start, remove the screws on the middle brackets first. Now you have only one bracket left on each side that hold the shade in place. Here you need two people each holding one side of the shade while the screws in these last two remaining brackets are being removed. Now bring the shade assembly down.
   
   If you have any problem on how to reach the screws behind the valence, consult with your vehicle manufacturer.

3. Re-installing the Shade Assembly

   To re-install the shade assembly, follow above instructions in reverse order, making sure that all the brackets are fitted with 2 screws again and that all the screws are well tightened. 

4. Adjusting the Limit Positions

   After re-installation of the shade assembly, carefully run the shade up and down to check the limit position; if they need adjustment, please refer to QRG #2 if your replacement motor(s) is a standard motor 4280P or to QRG #7-2 if your replacement motor is an ignition-lock motor 4270P.
   
   Note 1:
   If you would like to only replace the motor(s) and keep the existing shade, please refer to QRG #16 for standard motor 4280P or QRG #17 for ignition-lock motor 4270P.
   
   Note 2:
   If, during the replacement process you notice that a safety spring in your windshield shade might be broken, please refer to QRG #20 for remedy.
