Sunroof can't close. Can't lower wind deflector.

[Snoopyslr]

I just started having an interesting issue. When closing the sun roof it gets to the wind deflector and bounces back. It's like the motor detects too much pressure and backs off (safety measure so you can't guillotine yourself). The roof will close just fine if I hold the deflector down manually. I've lubed everything I could up, but made no difference.

Does anybody know if there is a procedure to reset the motors limits or allowed resistance? I can't find any way to mechanically adjust the deflector. I did find on an Accord forum a reset button dance, but it didn't seem to do anything when I tried it last night.

I would just take it to the dealership. Dealt with this kind of issue on my driver side window for months before I took it in. They fixed it in an hour or two it was a faulty window regulator

I've been using Shin-etsu grease on my Hondas since 1995 or so. If you keep the seals and weatherstripping in the guides/channels lubed up; it seems to lower the resistance/friction of whatever is trying to move against it. Some folks use silicone. But it's something to try if ya' want.

It's not a binding or non-lubed issue. The issue is when the glass hits the arm to lower the wind deflector, it's creating more resistance than the motor is set to overcome as a safety issue.

Back when I worked at Ford as a mechanic, I had to constantly reset the window limits because they wouldn't close/open fully. It was a simple procedure involving the switch to reset the min/max limits. I was hoping Honda had a similar option because mechanically nothing is wrong. It's just triggering the safety prematurely.

Here you go.

Hope this doesn't sound stupid, but I don't think my car has this pop up wind deflector. Is this something that wouldn't be on a coupe?

My 2018 Si Coupe didn't come with one. I ordered one from HondaPartsNow and installed it myself. I lubed it up with superlube synthetic grease and have not yet had any issue with the sunroof closing.

But it's clear the system can have faults and needs to be reset, hence the guide in the service manual.
