When starting my 97 Blazer, often my ABS light stays on and power windows and heater blower won't work. Sometimes, eventually, the ABS light goes off and then blower and windows work. I have noticed that my brake light will come on right before the ABS light goes off and things work again. More and more often now, the ABS light stays on and I can never use my heater blower OR power windows!

 

Sorry for the slow response time. Forum problems at the beginning of the year meant a lot of new posts got missed. I do hope that you have cured your problem by now, if not, see below.

This sure sounds like a failing ignition switch.

 

i lost my power windows and blower tonight and my abs and ebrake lights are on just happened while i was driving and truck still starts fine. Any ideas?

 

It is possible that one side of the ignition switch has failed. Trouble shooting is required to narrow it down though. First check all of your fuses. A few wiring diagrams would tell you if those components have a common power source.
