Thanks. I located the pump, driver side inside the fender, now I’m trying to locate the fuse for the pump. The fuse box on the fender doesn’t show a label for the pump, do you happen to know which fuse controls the pump and how its labeled? ---

This is a quote from another forum, but it looks like the Air Pump has it’s own fuse box. Your S10 . has a small fuse box Next to the battery. 1 - air solenoid 10 amp. 1 - air fuse 30 amp. 1 - Mini relay (air relay) On under hood main fuse block you have. 1 - fuse Engine E 10 amp. Here is a link to a very detailed troubleshooting thread. [http://blazerforum.com/forum/showthread.php?t=19286](http://blazerforum.com/forum/showthread.php?t=19286) Here is the wiring diagram from the thread, the fuse names agree with those in the beginning of this post.
