#1853 of 2511 1997 Chevy Venture Electrical Systems Problems
May 23, 2005 (10:14 pm)
I have a 1997 Chevy Venture, which I have started having a few problems with lights dimming and the electrical system in general. I do have an amplifer and subwoofers added on to the system as well as an aftermarket cd player which can account for a total addition of 35 amps to 45 amps of draw. When my subs are turned up all of the way they do tend to make the lights dim. Also when I use the ABS the lights will dim while they are on.... That is a side note to my current problem with the electrical system. For the past week it has been getting worse In which I attempt to start the vehicle and it wont start the first few times, but on the 4th or 5th time if it give it some gas it will start up. Also, the lights now dim when the bass is turned up half way instead of all of the way. In the past two days, my ABS light will pop on at various times when i am driving normally and not even using the ABS, as well as the Brake light (in the insturment cluster) does the same thing. Today, it required a jump to get started and then after driving for 10 minutes the ABS light comes on so i turn it off and try to restart it (because that usually clears the lights in the dash cluster) it died again requiring a 15 minute long charge from a car before the jump start would work.
I'm guessing it is the alternator, but on a previous post someone mentioned a "10316685 Kit screw for Bosch generators" that fixed an electrical system problem? Is it the alternator? The battery? Also if i have to replace the alternator what is a good place to get an alternator with lots of Amps so i can eliminate all light dimming from my subs.?????

Have the alternator and battery checked. Also there is a TSB on a ground connection on the alternator for these GM minivans. Check to make sure this has been done.

There is a bulliten on this problem. It deals with a screw in the back of the alternator which has to properly ground the voltage regulator to the case of the alternator. GM has a screw kit with instructions on how to fix this.
#1856 of 2511 What is a TSB?

First thankyou for your quick reply's. Just a couple more questions. What is a TSB ground connection? Is that the thing with the screw that post #1855 is talking about, and if my alternator happens to be dead, how much should i expect to pay for a new alternator (or refurbished one) that is an OEM replacement? Also I was thinking of putting a bigger alternator to prevent my subwoofers from dimming my lights, how much more would a alternator for that cost as opposed to the previous? Finally, what should I expect for the labor charge (either number of hours or labor price) that would be reasonable?

Yes, TSB is "Technical Service Bulletin" as stated in #1855.

This may sound unbelievably simple and silly, but the same code came up on my wifes Venture. I found that she hadn't tightened the gas cap enough. You have to tighten it till you hear at least 3 clicks. If not, it will allow the fumes to leak out thus not allowing the proper pressure in the system setting the EVAP Emiss code. This might not be your problem, but is worth a shot. You may also want to make sure the gas cap is working correctly. They can go bad as well and do the same thing. Hope this helps.

Our van has got a bin which has slots in it for CD's to ride in. It is a little out of the way, but comes in handy!

Thanks your note and had it fixed sometime ago, so far all OK, but find lights in the switches are dying off and one in the fuel gauge.
#1861 of 2511 200,000 miles on my 2000 Venture

My ugly brown van has been a great car for me and my kids.
My problems have been minimal over 200,000 miles, but include the following and resolutions:
If you have ever changed the air filter, it is a PAIN. Get a K&N filter, it does not need changing very often, increases gas mileage, and it is reuseable.
Change your plugs more often than 100,000 miles. Ask the mechanics for the used plugs - there was nothing left of mine, and it really puts a strain on the ignition system to bridge an enlarged gap. You would be amazed at how little is left of them. My mechanic can put the car up on the lift and change them without lowering the engine.
Change your fluids - transmission every 50,000 - mine was not and a local dealership messed up a warranty repair on a valve assembly - the combination equalled a new transmission.
LOSE THE RED ANTIFREEZE!!! - That stuff will eat your gaskets, especially the intake gasket. After only 40,000 miles I changes mine out - it looked fine, but it washed out mud. I put in green and it stayed clean. The red turns very acidic quickly. I recently put in the yellow/orange universal fluid.
I still have the original brake rotors, all original brakes and pads on the back. Ceramic pads are on the front, a little more expensive, but great improvement in braking, and the rims stay clean. A pad change on the front of these is a snap!
I just got new struts and shocks - I was riding on nothing but springs. Well worth the cost, the back shocks are cheap and simple to change.
Get an induction treatment from your mechanic to clean all of the goop out of your intake. Mine gets so bad that my throttle plate sticks shut.
I enjoy driving my car, and I love the 25-28 mpg on the Interstate. I have a rattle that is a lifter or injector, not sure which. I am tempted to take off my intake and clean it out good. I got the idea to get a shotgun cleaning kit and try to use it to reach in and clean it out, but have not tried it yet.
Hope this helps someone someplace!

There are two different alternators listed for the Venture - one is for most, but I believe that there is one that has a higher amperage to handle vans equipped with AWD or the rear air compressor. Alternators are expensive, and the labor is worse. There is not enough room to fit over the engine, so everything, including the wipers and motors on the passenger side have to be removed, or the engine rotated down. Very time consuming and labor intensive, and the compact space-saving size means extremely fine, tight windings inside the alternator - life expectancy is only about 60-80,000 miles!
