1991 Chevy S10 Speedometer Not Working. Its exposed to muck and grime etc. I have a 1991 S-10 Blazer 2 door 43 4x4. The fuse should also supply power to the rest of the cluster. Easy fix just replace worm gear.
91 Chevy s10 pickup. For parts or not working. Your 1991 Chevy caprice has a digital speedometer that has power and shows 0 as you drive AFter 20 min then the speedometer works and shows your speed what is. The air bag warning lamp should flash seven times. 35 of the time its Vehicle Speed Sensor VSS. Jul 08 2014.
I hope this helps.
Easy fix just replace worm gear. I would crawl under and check the connector at the tranny. I have a 1991 S-10 Blazer 2 door 43 4x4. While there are a variety of reasons your Chevrolet S10 Blazer speedometer is not working the most common 3 are the vehicle speed sensor VSS a faulty speedometer or an electrical issue. Each part should be set and linked to different parts in specific manner. I replaced the speed sensor and the instrument cluster and it is still not working.
