Having problems with your 1997 Chevrolet Blazer ?
I have a 1997 Blazer. The ABS light comes on intermittently. When the ABS light is on the power windows and blower motor do not work. When the ABS light is off everything works just fine. Help????
That sounds strange about the power windows and the blower motor not working when the ABS light comes on. I happen to have a 99 Chevy blazer and I had the ABS light come on several times. There are ABS sensors on the two front wheel bearing hubs. If you take off the front wheels you will be able to see a black electrical cable that has 2 wires inside of it. This cable is coming directly from the ABS sensor on the wheel hub and is strapped to a bracket the is on the upper ball joint. From the hub it then goes to a plug connector that is under the protective flap that you lift to change your spark plugs. What I found that is a common problem is that wire tends to corrode or doesn't have enough slack in it when making turns and starts to pull and break. Examine that cable and if you see any breaks in it, that will cause the ABS light to come on. Also if you can get to the plug underneath the flap, unplug it and use a multimeter to see if you are getting any resistance on the two wires. If you aren't getting any resistance then your sensor is bad or you have a broken wire to the sensor. On my vehicle the ABS light kept on coming goin on and off intermitently and I found that wire from the sensor to the plug had a break in it. I stripped the wires back, spliced them together, soldered them and I used heat shrink tubing to cover the connections. The ABS light went out and it has been fine ever since. Hopefully this will solve your problem as well.
Check body wiring grounds, battery to frame or starter, body to frame. When an electrical ground is bad on one circuit, it can use another circuit (ie windows or blower motor) to complete the circuit to ground.
