I am having great difficulty fully closing sunroof

[Joseph C]

Hi there. I apologize for what, on the face of it, may appear a dubious, or silly question. But I assure you, it is a problem I have had on at least two vehicles: Previously a Ford Expedition, and, in this case, a 2003 GMC Envoy XL.

The issue I am having is that, I open the sunroof. Cool.. BUT, when I CLOSE the sunroof, it APPEARS closed. UNTIL I GO THROUGH A CAR WASH.

So. I ask.. How do you FULLY close a sunroof on, in this case, a 2003 GMC Envoy XL?

Thanks.

Do some internetting and look for a sunroof re-learn procedure. Try a re-learn and if that doesn’t work successsfully, there is some sort of a mechanical issue going on.

Often times, especially on Gm vehicles if battery voltage is lost it will effect anything with a “calibrated” motor, like hvac actuators and sunroofs.

Try to check in the trunk of your vehicle where the emergency jack is. Usually there is a wrench to remove the lug nuts and there should be a smaller looking wrench to manually close the sunroof. Usually all the info will be in your Owner’s manual.
