Sunroof glass fit

[Texasram1]

How do all of your sunroofs fit? My glass is high in the middle back, such that the seal protrudes above the cab. Is this normal? It makes wind noise on the highway.



If the dealer adjusts it so the middle back is flush, the back corners are below the roofline. This also yields wind noise.

Does anyone have sunroof glass that matches the roof contour?

Mine does that too! I tried all the recalibration procedures I could find, none worked. Does anyone know how to fix this? The glass is too high on the back when fully closed, makes wind noise and might get some water in when going through the carwash...

Here is what I tried:

From the 2019 Ram 2500 Owner’s Manual & Community Sources​

From the manual:

• The 2019 Ram 2500 has a “Relearn Procedure” for the sunroof when the Express Operation (one‑touch open/close) stops working. ManualsLib
• To reset:
  
  1. Ensure ignition is ON / in RUN mode. ManualsLib+1
  2. Use the sunroof switch to close fully. ManualsLib+1
  3. Release the close switch. ManualsLib
  4. Within 5 seconds, push and hold the close switch again. The sunroof will cycle (shade close, then open & close, then shade close). ManualsLib+1
  5. Once all motion stops, release the switch. The sunroof should be calibrated and express open/close restored. ManualsLib+1

From user / forum sources (for Ram / similar vehicles):

• Starting from the fully closed position:
  • Press and hold the CLOSE/forward switch continuously.
  • The sunroof will make a “hard stop” movement, then shade will close, then it will cycle through open & close, then shade close again.
  • Only release once everything has completed. (If you let go early, the calibration may fail) Reddit
• If the motors or any part of the sunroof assembly has been replaced, reinstallation can require a special reinitialization mode. Reddit

Step‑by‑Step (Refined for 2019 Ram 2500)​

Here’s a combined, practical procedure:

1. Turn the ignition to RUN / ON (accessory or full run mode such that power is available to the system).
2. Ensure the sunroof is fully closed (glass panel and shade).
3. Push and hold the sunroof CLOSE (forward) switch.
   
   • Continue holding even after it seems closed.
   • Wait for a “hard stop” movement (motor may click).
   • You should hear/see the shade move to closed if not already.
   • Then the roof should cycle open → close.
   • Then shade will close again.
4. Only release the switch after all movement stops (end of the cycle).
5. Test express open/close, and venting, to see if the functions are restored.

If it doesn’t work, repeat the process. Make sure no obstructions are in the tracks and the rails are properly lubricated.

Have you tried the glass adjustment screws on each side to just lower the glass a bit?

I will look for them, I have not seen them...

Ok if you need I can take a pic of them. You must do the adjustments with it in vent as to not bind/bend the mechanism
