1998 Chevy Blazer 6 cyl Four Wheel Drive Automatic 110000 miles
The other day when starting the car, the battery warning light stayed on. The volt meter was lower than normal but after a couple of miles the volt meter went up to the normal reading and the light went off.
The next day, the check engine light came on and has been on for 2 days now. Volt gauge is normal and no battery light on. There is no noticeable change to the running or performance of the car. I have checked the engine belt which seems fine, and there is nothing obvious wrong. Any ideas?
I perhaps should mention that there has been other electrical issues in the past, like the ABS warning light that comes on and off every so often, problems with the windshield wipers doing there own thing, but there has never been any problems with the running of the car.
The " check engine" light is an indicator for a system that monitors many electronic functions in the system, also called the " malfunction indicator lamp" (MIL). It can come on for any of hundreds of different causes from any of the systems that the computer monitors. Some are very important and can lead to further component or engine damage and some are emissions related not as serious but still a problem and need to be repaired.
Your first step is to have the computer scanned to retrieve the trouble codes that were set when the check engine light came on. Those codes will give you specific information about what the computer saw and will get you pointed in the right direction to find your problem. With a 1996 or newer and some 95 cars and you have an AutoZone or Advanced auto parts in your area, they will read them for free. Once you have these code numbers, we can be a lot more specific about what your problem may be.

I agree with the previous statement, have it scanned. As far as your ABS light, most likely a wheelbearing, as you have sensors located in them. While your there, check the balljoints! They always go bad.
