Ok so heres the deal; 2000 Safari passenger w/ a brand new alternator. The van cranks fine cold, and the voltage gauge is cranked to 3/4. Then as it warms up it dials down to where it should be. When I go on the highway the stereo's volume increases by itself and when I am idling the volume decreases as well, plus when I put both windows up at the same time the guage almost drops to dead... Battery tests come out fine... Gauge also fluctuates when I crank the heat or turn on rear defroster. Any thoughts? Also, I have had GM's for a while and after a long trip (or also when they're about to crap out) I hear the fuel pumps whining. I hear mine whining like 5-10 seconds after I turn the van off... Anything about anything would be appreciated!

Its very likely that your ABS Module needs to be refurbished. Mine was doing exactly the same. Vibrations seemed to set it off and both BRAKE/ABS lights would come on until I turned the car off. It is a popular problem with the modules.The fix was less than $100 dollar and it was very easy.
There are two companies that do this and give you a warranty for their work:
ASI (Automotive Scientific Inc) www.AUTOECU.com (HINT: their Ebay listings are way cheaper! http://myworld.ebay.com/ate1234)
And the other company is Module Master: http://www.modulemaster.com/en/index.php
You can ship it to them and still drive your vehicle. Your brakes will work just fine, but the ABS feature won't until you replace the controller. Just make sure you cover the other half of the ABS unit on your car. You'll want to protect it from debris and water.
Best of luck.

#151 of 152 2000 astro van starting, no heat, power loss problems by scwand51

These problems seem related, all started around the same time - won't start on 1st key turn, if doesn't start on 2nd try sometimes won't start for a long time, minutes, hrs. or even days. The heater and the A/C won't work. Massive loss of power and tremendous fuel consumption. Shifting from 1st to second hesitates. If you have any clues or solutions, I'm all ears. Thank you so much.#152 of 152 Re: For THOSE SUFFERING with the BRAKE/ABS LIGHT [bsibaja] by rpep

Thanks for your input. Sorry it took so long to answer. I was out of the country for a few months.
