Hi,

I have a 2003 Silverado and this morning on my way to work the blower shut down and then started back up and went straight to high speed and is now stuck on high. I get to work and shut the vehicle down and the blower is still running????????? I had to disconnect the battery so it won't run all day. Any idea what would be causing this?
HELP


Thanks,

something is keeping the high speed blower relay energized. either a short in the wiring, or most likely a bad relay
