I'm looking at eBay listings for seats. Some of the Chevy full-size pickup bucket seats (manual, not power) have adjustment knobs on the outer side of the seat bases near the front (ahead of the recline lever). It's a hefty knob with big grip notches molded in. I've seen them on both the driver's and passenger's seats. The ones I've seen say 99-03 application.
Are these for seat cushion height/tilt, or lumbar support, or what? If this isn't the lumbar adjustment, where is that?
Some of the seats have this knob, plus what I think is the the recline lever a little farther down and back on the base, and then another lever at the lower end of the seat back. I assume this additional lever is the release to tilt the seat forward. I'm looking for seats for another vehicle project and don't know the
1500 very well. Thanks for a quick response.
