I searched the past posts and didn't find anything that related to this problem. Hope someone can help!

I have a 97 Blazer LS that has the weirdest thing happen. The ABS lights and the Emergency break lights flash while driving. While this is happening I have no A/C or heat, the fan doesn't work, and I have no power windows. We have replaced wires and searched everywhere in the vehicle we can think off to find the problem.

This problem has stumped everyone that I have asked so far. If anyone has any advice/suggestions they would be greatly appreciated!

Chekc the fuse panel for a worn through wire.

I had the same problem on our 1997 blazer. We had to replace the ignition switch in the steering column. The switch is not sending power to a relay under the dash that will make those things work. Beleive me I tried testing everything and this is the one thing that fixed the problem. Let me know if you get this fixed. Hope this helps.

Yea, the ignition switch would cause this, thanks for pointing that out.

Yep....it was the ignition switch. My mechanic did a swap test just to be sure that it was the ignition switch. It got fixed and the heat wave ended. Thanks for all your help.
