I was wondering of anyone else has had this happen to them? I called Onstar and they ran a diagnostic but nothing came up. I did though manage to find out how to disable the automatic headlights and go manual ,but want to know how to fix this properly. Any suggestions?? I really don't want to have to go to the dealer if i don't have to.
Thanks~
As stated above our experiences seem to be similar in that we are unable to start the Suburban in the mornings when the vehicle has sat for several hours. Then once started after several attempts it dies when traveling down the road. I also noticed that it started accelerating in a school zone from 20 mph to 25 mph in a matter of 50 - 75 yards without pressing the accelerator.
We just put in a new battery two weeks ago and just did our 60K service at the dealer.
I will post again after we find a solution.

If a sensor that both systems use goes bad you'll get warning light for both systems.
First check sensors that they have not been knocked off correct alignment to the signal sending wheels that they read. The end of a sensor normally is mounted really close to the wheel it reads. I have not looked at the sensors in my Tahoe but an old Ford I used to have had only about 0.030" gap between the sensor and the sending wheel.
Check the wiring, especially the wire harness. Sometimes moisture penetrates inside harness and corrodes the contact pins.
If wires, harness and sensor alignments are ok BUY ONE SENSOR and rotate it in each wheel to see if you find a bad one. I don't know how much a sensor cost but to take your car to a dealer or anybody else for diagnostic will cost you $70 - $80, which easily is more than the sensor cost. For example the crank shaft position sensor that I believe works exactly the same way as wheel speed sensor cost $63 + tax.
I'm not sure if ABS and traction system warnings set a code in your car's computer but to check for that can be done for free at AutoZone and perhaps in other car part stores. If there is a code it probably says what sensor is bad if it is a sensor problem.
Usually wheel speed sensors are easy to change so little work can save you few hundred dollars.
I'm talking about the wheel speed sensors here because I don't know any other parts that ABS and traction systems have in common. This does not mean that there isn't any though.
As today's cars all have a lot of sensors to go bad I recommend to purchase a scanner that reads and resets computer codes. I bought an OBD II scanner years ago for my Ford as all cars have connection for it since 1997 I believe. Scanner has saved me its cost many times over as it only cost about $100.

The one I'm looking at has 200,000 miles, a rebuit transmisstion and transfer case. A/C and power steering.
How many miles have well mainained Suburban's been known run for?
What is a reasonal price to pay for this vehicle?

Thanks for your help
Does anyone know if their is a model crossover from one radio to another or if a radio from a silverado would work in a suburban if the connectors and mounting looks alike? Thanks!

I solved it by putting a marine on/off switch on the positive battery wire...still can't find the short ! Can't use electric door locks or alarm with the marine switch.

looking underneath it appears i'm missing some brackets, and from what I heard If your burb didn't come with factory boards you can't add them later.
I know what the missing brackets look like, but want to know if the above statement is true. and where can I get them at?
also the new to me burb the rear window wiper and defroster don't work. Any thing I should look for when repairing these things?
Same with the cruise control.
Thank you

Any ideas?

The way the meter helps is that you will see immediately which circuit the problem is if you go pull fuses one by one. The amp amount should be very low when car is standing without having any assessories on. I talk about 0.05 A or so. If you read 0.5 A when car is sitting I think you have a problem, now it is to go find it, which work you have been doing already.
Did you ever disconnect the alternator? Often the diode bridge in the alternator goes bad and can cause battery drainage. Alternator would still work but if the car sits for a whole day or so it might not start any more. When disconnecting the alternator take first the thick charging wire off. If amp reading does not go to zero then disconnect the wire harness with 3 or 4 small wires. If amp reading now goes to zero then you need to replace the alternator. If amp reading stays the same your alternator is fine.
I had a similar problem about 12 years ago with an 1982 Chevy Impala. I'm in a heavy traveling job and my car sits in an airport parking lot a lot. When that car was sitting for 3 days I would need a jump. Any shorter undriven time did not drain battery enough to cause a problem but that third day did it.
I found the problem being that someone who owned that car before me had connected the cruise control in a fuse that was fired all the time. That caused a draining amperage at about 0.6 A, which was enough to drain my battery in 3 days enough so that the car would not start any more.
Another symptom was that my cruise control always remembered a speed setting even after car was turned off. If you have this problem you can easily test for it by pushing the resume switch without first setting the speed. If the car remembers a speed it means the power for cruise control was not turned off when car was.
Connect an amp meter on your battery cable. It really helps in trouble shooting your issue and it should show which circuit the problem is when you pull the fuses one by one.
If after pulling all fuses and relay switches the amp reading still stays and you have checked that the alternator is not doing it about the only thing left to check is the starter motor, which can also be easily disconnected.

Any idea if this is where this o-ring goes and what happens if I'm wrong?
Thanks.
It did the job
Thanks for your help.
and washer. Check all 6 or 8 body bolts, and make sure they are all tight.
These are the 6 or 8 bolts that connect the body to the frame.
fuse until the draw goes below 1 amp. Reinstall each fuse one at a time,
and look for 1 or 2 amp gain in draw. Concentrate on the one circuit that
has a big draw. You should not have more than 3/4 amp draw.
After market radios are a big problem, along with add on stereo equip.
and it will come out. Get new light at auto-zone etc., for few $$ and put
back in. Easy.
I decided to replace these batteries every 2 1/2 years, and no problems
ever. I have 2 subs, and a tahoe, and changed batteries on both subs,
no problems. Tahoe is close to 2 1/2 years, so a new battery is on the
horizon.
Cheap insurance for having no problems.
can fix this without replacing the whole seat covering.
What I did do, was take a small knife, and carefully cut the tab off right at
the leather fabric. If I did not show this to anyone, they would never notice
it.
