Unfortunately you have a completely different truck than what everyone on here does, you have a S10 platform Bravada (90s-00) and not a GMT360 platform Bravada (02-04). You have a 4.3L V6, the GMT360 has the 4.2L I6. About the only shared parts are the transmission between these trucks.
Id recommend searching and then posting on www.s10forum.com for a better chance of getting an answer. Good luck getting your answer!
Sounds like your clutch isn't engaging. Check the fuses. Sometimes, when the correct recharging gas isn't used, the compressor won't engage because it isn't being oiled properly. It will stay off to protect itself from getting damaged
You haven't charged it if the clutch don't come alive. Sometimes the kits you get at auto-zone and the like don't want to take. I have tried before with these and failed to get it to take. I put my 30 lb can and robinair gauges on it and no problem. BUT sometimes it is just a bad compressor. These for your truck are reasonably priced tho. it is 134a right?
