    Anyone know the part number for the fog lights? I have been looking for the part to see if I can replace them with brighter lights. I would like to add HID's if they are available for the fogs, I know they have them for the HB.

    They done gots balance shafts:

    5 cyl "no longer inherently balanced " just the opposite as I recall. One of the supposed advantages of the inline 5 cyl configuration is its inherent balance without adding balancing shafts etc

    Hmm.. musta slept since then. Coulda sworn I read that referring to one of the other I-5 engines as to the advantages of 5 vs. 6 cyl etc. Thanks for posting the link! Sounds like a smaller engine with more internal moving parts to make it work right.

    I've recently noticed a couple of things about my 2003 Envoy - I'm looking for some advice if you have any to give.

    First: my parking brake handle seems really crooked. I had not had any reason to use it until last week. When I went to release it so I could drive off, all of my fingers that were curled around the handle got smashed because they were pinched between the handle and the side of the console (the area where the handle resides when it is down). Looking closer, I have noticed that the brake handle and shaft is totally crooked and is almost touching the side of the console. Does anyone else have this problem? I am going to take it to the dealer soon and have them look at it and hopefully straighten it out so I don't smash my fingers any more!

    Second: My drivers side door is way out of alignment - its difficult to open the door some days. And this past weekend when I went to open it it opened all the way and bounced against the stops and I happened to be looking at the hinge when it did this and I saw a big crack forming where the hinge is welded to the door! How in the heck did that happen and can it be fixed?

    Thanks!

    I guess GM thinks everyone's forgotten about the Cadillac V-8-6-4 from the early 80's. Hpoefully 20+ years later they finally figured out how to make it work.

    My Envoy is back from the dealer and I found out that the "dark stuff" in my coolant expansion tank was dried coolant. They drained the system, removed the expansion tank, cleaned the expansion tank (tech indicated it took 45 minutes!), flushed out cooling system, and filled with new Dex Cool. All performed under warranty (would have cost $113). Service Manager could not tell me WHY this happened (but he seems to have seen it before). I would suggest everyone look at their expansion tanks and checking them out before the warranty expires.

    Sounds great on paper, but according to the article if will boost fuel efficiency by 8%. So that means if a vehicle gets 20 MPH on the highway without DOD, it gets 21.6 MPH with DOD? Makes you wonder whether it's worth the extra cost and headaches.

    If I remember correctly (remember this is eons ago!), what was surmised in some of the most severe cases (hundreds of feet of uncontrolled motion in some cases), was that the driver was pressing only the accelerator. Regardless of the driven wheels (normally the engine should stall before the brakes are overwhelmed), the non-driven wheels would definitely lock on full application of the brakes, and skid marks where never found. And yes I know about Quattro drive; many 5000s were FWD only.

    What some wanted to claim was that at a given moment in time the throttle opened wide on its own and simultaneously the brakes totally failed. This was never replicated in 100s of tests.

    Just a point of clarity - if you've got tons of torque, the brakes don't win when you press both pedals. I haven't tested this on my Chevelle yet, though.

    And gee Steve, can we stick to topic? :^)

    Volvo is making gas I-5's for their cars. I think they may be the only one with any I-5's these days. I-6's and V-12' are the best of the bunch for ballance.

    As far a Audi 5000's, I remember Car and Driver doing a test where they ran the Audi to 70 mph, floored it while hitting the brakes. While it took more brake pressure to stop the car, it did stop, and only took about 10-20 ft more than with the throttle released! THAT test never got much public attention.

    My Envoy finally showed its first defect after 15 months and 15,000 miles.
    My wipers decided that they wiped their last raindrop. At least they made it through an extremely wet day here in Chicago on Saturday before retiring. I went out Sunday morning and as I turned on the washers, all I got was washer fluid sprayed on the windshield. I had to pull over and wipe it by hand. After checking the fuse and tilting the steering wheel up and down repeatedly, thinking it was a wiring harness thing, I gave up.
    I took in in today after work. They said that the wiper motor had shorted out and fried. The mechanic claimed that water had been seeping onto the electrical contacts/connector of the motor, which corroded and caused the short. He said that he's seen this before, so beware.
    I have to wait 2 days for the parts to come in. I'm praying for blue skies!

    Sorry Scottc454, all that Audi talk got me curious. I did refrain from posting the other 6 or so links I found :-)

    I'd post a link about "displacement on demand" but y'all beat me to it...

    Now the question is whether the incentives will be suspended since the plant is closed due to the recent tornado.

    My TrailBlazer turned 40k this past weekend. Still running strong!

    2002slt: did your wiper motor act up before quiting. Recently, my TB wipers hesitate mid wipe if in the slow or auto rain sense mode. I was wondering if this is normal to the auto rain sense mode.

    Ficuss,
    They have worked flawlessly since last June. Back then I had a problem where they came on during a car wash while the switch was in the off position. Each time the spray hit the windshield it did this. I don't have the rain sense option, so it was really strange. It never happened since, so I just ignored it.

    with all their years of experience, GM would have figured out how to make reliable windshield wipers:

    GM Recalling Pickups for Wipers
    Date Posted 05-08-2003

    Faulty windshield wipers are again causing General Motors to issue a recall on its vehicles. The company will recall nearly 1.77 million pickup trucks, SUVs and vans in an extension of an earlier recall that replaced wiper circuit boards and wiper-motor covers. The problem hasn't caused any fatalities, the company said in a release. The vehicles affected include the 1994-1997 Chevrolet C/K and GMC Sierra trucks; Chevrolet Tahoe and Suburban/GMC Yukon SUVs; 1995-1997 Chevrolet Astro and GMC Safari vans and Chevrolet/GMC full-size crew cab trucks; 1996-1997 Chevrolet Blazer and GMC Jimmy mid-size SUVs, and Chevrolet S-10, GMC Sierra and Isuzu Hombre compact trucks.

    ficuss,

    My wipers started acting up last week as you describe. On fast, they work great, on intermitant speeds they work great - BUT on the regular setting (one below fast), they have a mind of their own! They may stop altogether, they may run a ramdom intermitant cycle, it varies from day to day.

    Had the same problem (twice)when I picked up my 2002 Envoy. Whats happening is that there is water inside the wiper motor!! As you go around a corner or in some cases over a bump the water makes the contact that activates the motor!! The second time it happened I watch the mechanic open the motor housing and no less than a cup of water come pouring out. They put a new motor in and it has not occurred since.....that was 10 months ago.
