I have not looked at the Rainer/Envoy/Trailblazer plugs and coil packs. I will look at them soon since it is about time to change the plugs on my wife's Envoy. If the coil packs are similiar to the ones on my '00 Trooper it is possible that one or more will be difficult to break loose from the plug. Trooper has a rubber tube covering the spring down from the coil to connet to the plug..tend to get stuck and difficult to remove. IF that happens do not try and force them off since they can tear and if that happens you might have to replace the complete coil pack. Take compressed air and blow down the center of the rubber tube and it will pop right off. I used one of those small 'compressor' you can get for $20-$30 for inflate your tires...worked real well using one of the pointed inflater tips that came with it. You could probably even use a manual pump but might need assistance to hold it in place.

Do any of you know if GM has discontinued the Trailblazer, Envoy and Rainier. I heard that neither one would be produced after the '08 models but I haven;t been able to confirm this. Thanks

I went to gmsupplierdiscount.com and looked under the incentives they list... None of these were showing up in the list of 2009 models but were there for the 2008's. Interesting that they were showing $6000 incentives on the 2008s. But that does not really confirm either way.
 
Edit... I next went to www.gm.com, selected GMC, then went to Build Your Own.. chose 2009 and the Envoy does show up there. So, maybe they are still building them after all.

Have a family member that weighs towards 400 pounds. Any SUV model or sedan that can take that weight on a constant basis?

in your message about trailer towing you mentioned that the air suspension worked great to keep the load level---I am getting conflicting answers about the auto air suspension on my 2005 rainier some GM people say to disengage the system when towing others say leave it alone these same conflicting answers are also coming from RV dealer service people---so who do I believe which mode should I tow my trailer in----any insight from you could be very helpful
 
thanks

HandyAndy3:
 
I do not have the ability to turn the air suspension on or off in my Envoy. It is "on" all the time and usually I hear it come on every time I start the car. It has done that since new. I can turn on or off the aux. air pump outlet located in the passenger side rear panel in the cargo area. I cannot imagine why someone would not want it on when towing unless there was some fear it would overload the system. That has never happened to me. I would think that even if you could turn it off while towing that the back end would sag lower due to the extra weight of the trailer tounge. My Envoy has the extra duty towing package so I have always assumed that the air rear suspension was designed to work in towing situations. Mine is a 2002 that I bought new 7 years and 1 month ago and the air suspension has worked the entire time. We have towed with it during the summer since new. Our boat/trailer weighs 5000# and the Envoy tows it just fine. Does your owner's manual say anything about it? Do you have a switch that lets you turn the air suspension feature on and off? On mine the air suspension has air bladders instead of rear coil springs. I replaced the rear shocks last year but they are not connected to the air suspension bladders and are just plain old shock absorbers.
Good luck and keep us posted!

I have only had my rainier for a month now and did not tow my trailer (4800#) with it yet because I wanted to be sure about the air suspension----the fellow from the help desk at buick customer service told me to disable the system by just pulling the fuse when I am towing----I think that I will judge for myself by towing with and without the suspension activated----I am going camping for the holiday so I will try it at that time and let you know what happened

"the fellow from the help desk at buick customer service told me to disable the system by just pulling the fuse when I am towing,"
 
That sounds like the absolutely most absurd "customer service rep's" advice I've ever heard.
 
If towing something caused an adverse response in the model you own, the manufacturer would have designed something a little more "sophisticated" than pulling a fuse.
 
And I would sure get hold of the franchise owner and get, in writing, what he would suggest in the situation you describe.

The air bladders can handle the rating of the hitch. I would not tow with the suspension system turned off because the back end will sag like crazy and the handling will probably stink. If you are concerned about overloading the system, check your trailer weight (fully loaded) as well as the load on the hitch. You should be able to do that at any public scale.
 
Good luck.
