#16724 of 18177 Rear A/C in Envoy XL by champton488 Jun 03, 2005 (8:30 am)
I have a 2004 Envoy XL, and am having problems with the rear A/C. I had taken my Envoy in for the GMC dealership to look at this problem. See article # 15825. I took it in during the winter. Now since it is spring/summer I am having the same problem. Now the rear A/C blower has come on by itself and keeps running until I do 1 of 2 things, 1. Turn on the rear A/C or 2. Shut off my Envoy. The bad thing is now it blows really hot air; unless I turn on the A/C then it blows cold air. I can't see always running my A/C to prevent this, especially with high gas prices. So has anyone else experienced this problem? If so what is the fix. I have another appointment to take my Envoy in on Tuesday and would love some fire power. Thanks for all your help.   Cary

Replying to: bigsexy (Jun 02, 2005 3:29 pm) The idle should be in the 700-800 RPM range. What is your voltage reading...top right instrument with battery icon? Is it stable or does it flunctuate? I had a battery leak a year ago and it wreaked havoc on the computer causing hard transmisson shift and my voltage and idle was off.   -gmfan Replies to this message: bigsexy (Jun 03, 2005 2:23 pm) bigsexy (Jun 03, 2005 2:24 pm) gmfan (Jun 06, 2005 5:24 am)

Replying to: mcupps (May 17, 2002 9:19 am) I put in 61/2 mb quartz in my envoy. You have to modify the speaker holder to place them into the holder. There was a lot of custom work put into it but it is totaly woth it. If your gonna put speakers in buy quartz they are much better then infinity. I used to have the kappas and the quartz blow them away. any questions feel free to ask.
#16729 of 18177 Synthetic Oil by twinrotts Jun 04, 2005 (5:32 am)
I have been running full synthetic Mobil 1 for a couple of years in the 4.2 but have the piston slap. Goes away in a coupe of minutes. This is probably the tightest engine I've ever owned as it has never needed oil added between changes and with the synthetic I go 7K or more. I ususally watch the oil change reading in the DIC and allow it to reach 40% or so
#16730 of 18177 Envoy Denali by blink3 Jun 04, 2005 (3:20 pm)
Anyone with one of these out there? Looks sweet, with the 5.3 in the standard (short) Envoy, it should scoot pretty good, and it gets 20mpg hwy. That is only one less than the 4.2. I have an '02 Envoy now and I put about 1000 miles on it a week. Very satisfied with it, but wish it had a 5 speed trans to keep peak power more available. Would love to hear some feedback from Envoy Denali owners out there. Replies to this message: ross1962 (Jun 04, 2005 4:17 pm) 01_hoe (Jun 04, 2005 8:36 pm) 01_hoe (Jun 04, 2005 8:38 pm)

Replying to: blink3 (Jun 04, 2005 3:20 pm) What I'd like to see is a short wheelbase TB with the 5.3. I really have no complaints with the silky smooth I-6, but ..... there's noting like a V-8! Replies to this message: 01_hoe (Jun 04, 2005 8:36 pm)

Replying to: ross1962 (Jun 04, 2005 4:17 pm) You will get your wish with the '06 TB. Will have a 5.3L available in SWB in all trim levels. You could just go all the way with the TB SS and the LS2 engine
#16733 of 18177 Re: Envoy Denali [blink3] by 01_hoe Jun 04, 2005 (8:38 pm)
Replying to: blink3 (Jun 04, 2005 3:20 pm) Not an owner (yet) but have driven some of them. The 5.3L is very noticable, as it moves out much better than the 4.2L even as tight as the new engine is at first. They are a nice ride.
