My blazer is a 2001 with the 3 button switch there is no auto mode on it

Wooo Hooo it's fixed I pulled the 3 button switch off the dash by gently prying it off with a plastic knife and found the harness almost disconnected. I reconnected it and pulled the 2 ECM mini fuses for 10 mins and presto it worked.

Wildman,

Good work, the old Do It Yourself spirit....F-ck with it until you figure it out. Great job and thanks for posting back the fix!

2 ECM mini fuses????

Where are those at?

My switch is not working either. i did the same as you, but everything is connected.

Where are the 2 ECM mini fuses located at? so I can try to reset them. Thanks

in the under the hood fuse box on the drivers side both fuses are near the center of the box. If you need the diagram for a 2001 I can take a pic of mine and post it.
