You may have an ignition switch that is starting to go bad. The next time the problem occurs try wiggling the key cylinder slightly to see if you can make the problem go away or turn the vehicle off and restart it and see if that helps. I see a fair number of these switches go bad and many have the same symptoms you are describing. What I usually find is that one of the internal contact points goes bad and won't always make a good enough connection to get power out to that circuit. Hope this helps and good luck!

Thank you SO much for this tip! It looks like for me it is the ignition switch. I jiggled and wiggled but nothing happened. Then I gave it a firm knock on the top down with the palm of my hand and pow. Everything turned on! So where to find a NEW switch. . . But thank you SO much for the tip GREAT help! I joined the board just to pass the good word along.

Power distribution issue?


Bad fuse box or power center. The reason you have difficulty steering is power steering pump is not coming on. The abs and air bag light are on because of a fault in system. Windows don't work because of no power going to system with all this happened at one time a bad fuse box is most likely the cause

ABS and brake light will not go out sometimes when you start the truck. Then again you start it and all lights act properly.


hello tra.... these two issues are related. The ABS sensors often go bad as the vehicle ages. Once the lights start acting up the failure of the ABS is not generally far behind. The only bright light there is that the only function of ABS is the autopumping of the brakes. Once that goes, you still have brakes, you just have to manually pump them when on icy or wet roads.

The cost of replacing these ABS sensors, and ultimately the ABS system is generally cost prohibitive. Joe

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.

The age of your vehicle might suggest that wires in your interior fuse box have either come loose, corroded or shorted out.  The high current once like A/C and interior fan may have caused the wires at the back of the fuse box to become embrittled due to heat.  I once had a problem with my starter circuit where the wire became so hard it couldn't be bent.  I replaced the section of wire to the fuse box and all the starting issues went away.
The only explanation for the Airbag and ABS, is that they too go to the fuse box.  I suggest checking wires behind the fuse box for the affected circuits (if you can remove it enough to see and feel behind it).  Using the VOM you can check for power at your fuses and focus on the ones without power.  Then check those wires first (remember most circuits don't energize until the key is turn on).

Hi my name is Allen!

If the ABS light comes on this means there is a problem some where in the system. Go to AutoZone and have them pull the code for you, right down the code number and what it means and I will assist you in repairing the problem.
