This..but they ran all way thru '90. Some '91 didn't have them as GM switched seat belt suppliers. I have a nos set without the button.
They work when you open the door, the belt retracts. Button pushes a tab and spring tension releases, winding up the belt. Pretty simple. The lock is different from the release. A hanging weight, looks like a fishing weight, works on gravity to lock up.
9 times out of 10 its just dirt inside that stops them from working. Sometimes the clock spring is broken. I have pix of them all blown apart if you need.
I have many a day into fixing Blazer/Jimmy belts.
A little fun fact...the passenger belt can be swapped with drivers side. Just flop the reels from the retractors behind the plastic cover. Figured that out trying fix a frayed driver side.
These are a life saving parts so don't fool with them unless you are 120% confident in your skills.
