You are in the Chevy Venture
What is this discussion about?
Chevrolet Venture, Pontiac Montana, Oldsmobile Silhouette, Van

Many people look to used American vehicles as a value play. Save a bunch by not paying for new vehicle depreciation and pay less than used comparable Japanese brands. Of course, this assumes the car you are getting used is reliable in order for it to be a good value. Herein lies the problem with the GM minivans.
The high number of TSBs relates to engineering or design or manufacturing defects by GM and/or its suppliers when the van was originally put out. The TSBs are generally the solutions to these original defects. Oftentimes, the TSBs include new and redesigned parts. I know this is the case for our new intake manifold gaskets (2nd set) and our new A/C condenser.
I would suggest only buying a GM minivan used if you know all the service history of the vehicle. Ideally, this would be a one owner who looked after the vehicle him/her self or had it serviced by the book at the dealer. This is not a good used vehicle to buy from someone that doesn't look under the hood frequently and instead takes it to the cheapest lube shop for oil changes.
I have caught two intake manifold gasket failures, A/C condenser failure, A/C compressor failure, and tranny failure early and under warranty because I change my own oil and look at things on a regular basis. This is a high maintenance vehicle that does require attention.
As far a longevity, go to Autotrader.com and type in 1997 Chevy Venture/Olds Silhouette/Pontiac Montana and you will see a lot of vans with 100K-200K miles. I plan on getting at least 200K miles out of our van.
#1480 of 1617 Need Some Help With Buying Decision
Apr 22, 2007 (5:21 pm)
I would appreciate your help. I am at a loss as what I should do:
Which should I purchase:
1. 1997 Olds Silhouette GLS, 55K, immaculate shape, most all the extras, $7500
2. 1997 Chevy Astro conversion, also immaculate shape, 77K miles, $8000.
The tradeoffs: $600 less, fewer miles for the Silhouette vs. high quality conversion, more plush interior and extras, TV/VCP, better engine, less possible major problems.
Carfax is clean on both vans, both are local owners with no major repairs, and are being sold by dealers.
I just don't know which one to pick!

Question: did GM agree to pay for any of the problems with the intake manifold gasket failures after the warranty period? They told me that they did not know of any problems or TSBs for intake manifold gasket failures on my 1999 Montana.
Comment: on the Astro....they have a 4-speed aotomatic transmission which has been having lots of failures.

The dealer is not telling the truth if they were not aware of the issue of intake manifold gasket failure on 1997-2003? GM minivans. The gasket was redesigned in 2003 or 2004, I believe, to address the high failure rate. So the dealer is keeping quiet so as not to point the finger at GM.
Getting GM to help pay for the cost of replacement has been difficult for many people who had the standard 3/36 warranty. Some have gotten assistance and others have not. I can understand why many people have swore off GM after having to pay $800 to fix this problem right after the new car warranty expired. We were just lucky to have the 5/60 warranty.
We have not yet had an IMG failure since the second set was put on in Feb. 2006 under warranty.
#1483 of 1617 Door Lock Switches
Apr 27, 2007 (9:18 am)
I have a problem with a 1999 Venture interior door lock switches. I believe both interior door lock switches work since they will activate the door locks to lock but will not unlock the doors. The door lock motors work since I can unlock the doors with the remotes. Is this a BCM programming problem? Anyone have any clues to search for a cause of not being able to unlock the doors with the door switches?

Yes I have engine oil in the coolant and coolant in my engine of my 1997 Silhouette. I purchased the van new in 1997 and its been a great vehicle without problems for 150000 miles, 210000 miles if you count the miles towed behind my motorhome. I replaced the lower manifold gasket and the problem was still there. I removed the OEM oil cooler and pressure checked- sure enough the cooler had developed an internal leak that let oil into the engine coolant when running and let coolant into the oil when dormant. I may purchase a short filter thru bolt and eliminate the cooler. I also have a 2003 AWD and it dosen't have a cooler.

i have a 2002 venture with the same problem with the door unlock switch along with some other issues, i just had the bcm replaced and the new one programed, it didn't help with the door unlock switches or any of the other problems.

Buy new door lock switches, they're cheap and easy to install yourself. The plate they ride in just pulls up with your fingernails.
The interiors of these vans are snap togther.
GM parts direct, you can't beat 'em. Also can be had on E bay.

Lot's of similar problems with my 1999 Montana.....and others on this web site. A major problem has been the rear tail-light socket shorts out between the black wire (power) and one or more of the other wires in the socket (pig-tail).
GM used a supplier of sub-standard pig-tails with plastic that could not resist the heat....melts and allow a short.
I replaced the pig-tail.

Aug 23, 2007 (7:19 pm)
I seem to remember someone mentioning a rattle in their left rear underside of their Montana/Silloutte/Venture.
I have had this problem for 6 years....45 to 60 MPH speed. I thought it was the mud flap, but that was false.
Can't find anything loose, but while washing mud off of the left rear wheel-well last week I discovered that the hard plastic wheel-well makes a rattle noise. I'll investigate further...but does anyone have a similar problem??? Or solution?
