I just bought a '96 Chevy Blazer. The ABS light comes on steady. Attempting to troubleshoot, I found the lead power wires going to the ABS. One (black) is a ground. Two red wires are also present. One is from the battery and runs hot all the time. The other I'm not sure about, but isn't running hot ever aparently. Should this run hot from the ignition switch? Is it possible this is my problem? Also, I can't seem to find a schematic or any sort of diagram for this model. Does anyone know where to find one online?

You should read the codes stored in the ABS system to give you more focus on your diagnosis.

If you haven't found out by now:
Near the firewall on the passenger side should be a small tube rising up near the throttle body. It is no more than 1 inch in diameter and has a small cap.

Check and replace Disributor cap. Especially if this slow start issue occures on rainy or humid days more then any other.

Check and replace the destributor cap. They carrode inside, and have a tendency to collect moisture.

I like Sylvania Silverstar sealed beam headlights for my 1991 S10 Blazer.
#3657 of 3674 99 Blazer 4x4 4.3 L poss. transmission problem?
Dec 29, 2011 (7:59 pm)
My 99 4x4 blazer (160K miles) has had some problems with shifting for about a year now. The problem is intermittent, only begins after driving for long periods of time highway or city driving. Seems worse when the engine is hot.. Shifting gets very jerky between 1st and 2nd gears, also between 2nd and 3rd. Again, this problem only occurs after driving it for a while.
Any insights? My boyfriend and I are expecting and would really like to fix this problem so I'll have a reliable car to cart the peanut around in.. He's very capable and willing to look into any suggestions you might have. Great with troubleshooting, just needs to know where to start the search!
Should I get a transmission flush? Do you think it's a connector issue? I'm really hoping it's not my transmission that needs replacing!

NO! Don't get a "flush" but you could certainly opt for a transmission fluid drop, with a new filter. This is also a good time to examine the old fluid for signs of metal debris. Also, don't use additives. Do the fluid change and see how it goes from there. This is an old transmission so don't do anything drastic to it.

I agree with Mr. Shiftright, a flush is only good for the shop doing it, not for the transmission.
This kind of hard shifting is almost always due to the line pressure in the transmission being too high. There are several possible causes. The PCM computer is supposed to regulate the pressure based on the driving conditions. For example, more pressure for high RPM shifts, less pressure for slow speed shifts. so it could be a computer issue or a pressure regulator valve issue, or something else.
I think your first step should be to take it to a local (not chain) transmission shop for a filter and fluid change. Ask them to read the codes associated with the trans. Then you will have some knowledge of what to do next.
The design life of these transmissions is 70,000 miles, to last through the 50,000 mile warranty period and then a little more, so be prepared since you are already into the third life.
