hit return before describing the problem… I was going to change the speakers in the headrest but the zipper is stuck fast. I’ve tried lubricant etc but to no avail. Is there a trick or way around this or am I going to have to cut it open and sew it up?

Thanks

All I can suggest is push against the headrest a bit, to take the tension off the zip.

If its corroded, wd40 can help but you will need to soak it thoroughly with repeated applications and try to scrape softened corrosion out as you go.

Tapping the slider with a small hammer can help too.
Good luck
