CS window trim.

Recommended Posts

Hey everyone, I want to remove the black window trim that goes around the top/bottom sides of the rear glass and doors on the 88-93 CS International coupes.  I need to remove the nice ones from my 89 parts car to use on my 91 International coupe.  Are there any tricks to doing this?  I obviously don't want to damage them.  I'd like to remove the large piece of trim that runs between the rear glass and the quarter panel window glass also.  Any ideas would be great, thank you!

I've never touched trim on a CS coupe. I've removed all the trim on my 94 CSC at some point or another. Look for small bolts or screws first. Then carefully pry by hand and check for movement.

These might have adhesive on them. You might want to look into trim removals tools so nothing gets damaged. 

These arent easy to find pieces.

Does that help? Let me know if you need anything else!

That's incredible information, actually a bit overkill.  I don't want to remove the glass, just want to remove the trim around it.  I will look at this more in depth, I also have a body man (friend of mine) who is coming over to help me evaluate how to pull the trim.  Looks like some of it is non reusable like the windshield trim.  That's ok, nothing I can really do about that.  I mainly want to get the belt line pieces and the trim around the door windows, the upper and lower rear glass trim.  Thanks so much for this info.

I might actually have this same book, I need to look in my parts room but this stuff looks familiar.  Never thought about using it as reference, my mistake on my part.

Glad the info helps!



It’s from the GM factory service manual. It is an absolute MUST have if working on these cars! They tell you basically everything you need to know including diagnosing al issues.

They’re dirt cheap now too! Without the manuals my car would not be on the road!

What is the official name of this book? This was great information, can you post a picture of the front cover. I'm going to Hershey 10/11 and I'd like to see about picking one up. My back rear drivers side window leaks into the trunk and I'm needing to know the way to get the trim off so I can re-caulk the side & back window. thx

It's the original Oldsmobile Cutlass Supreme Service manual.  My cars wiring is from an 89, so I have the 89.  There were changes throughout the years, especially with wiring, that I would highly recommend finding the GM service manual for the make, model and year of your car.  

 

Saying this, there are lots of 89 cutlass supreme manuals on ebay.

Update,

I spend a lot of time this weekend finding window trim pieces for the STE and decided to tackle this same job on the International.  Thank you to everyone who commented and helped out!

I thought I would practice on this 95 CS coupe I found in my local yard.  If I messed something up or broke a piece of trim, it wouldn't have been too big of a deal.  Turns out, it was pretty easy to remove all the pieces.  Now I have two sets of perfect window trim to replace the bad ones on the 91 car.

So I just used a small flat screwdriver and slowly started to pry the trim away from the body.  There are metal clips that hold it to the body of these cars and it took me about 10 mins on each piece as I took my time and made sure not to damage or bend them.  I also removed the passenger side lower beltline trim as the window was broken and learned how to get them out.  I haven't removed the upper front door window pieces as you have to get the windows down in order to remove them.  The junkyard car unfortunately has bad ones on each door so I didn't mess with it.

Getting back to the front door lower beltline pieces, it's the same on the STE.  You have to remove part of the door panel and get the sideview mirrors off.  This will reveal two screws that you need to take out for this piece of trim.  Same for the back of the door, take off the plastic door hinge cover on the inside of the door frame to expose the screw that holds on the back of the trim.  Then I used a non marring tool to tap it out and over the pinch weld on the door.  Not too bad!
