1999 S10 heater blower problem
The blower in my '99 S10 has stopped working. It worked one day, and didn't work the next time I got in the vehicle. When power is supplied directly to the blower from the battery, it works. I replaced the switch panel in the interior of the vehicle thinking that the switch was bad, and that didn't work. I'm not sure where to go from here... Any help, and/or a wiring diagram of this part would be appreciated.

Most wiring diagrams are copy right. AZ web site may have some wiring diagrams. Also most public libraries have car repair info. Or http://www.alldata.com/products/diy/index.html

I've checked the fuses. After reading some posts here, my next course of action is to check the blower resistor...

Re: 1999 S10 heater blower problem
I found a blown 30amp fuse in the under-hood fuse box. I didn't know there was a HVAC fuse there the first time...D'OH! Anyway, I replaced that fuse and my blower works, but only on the highest setting. I took the resistor coils out and tested continuity across them and one resistor has no continuity so I think the unit is bad. I just wondered if you guys could either agree with my diagnosis or point me in the correct direction....thanks!
