#16837 of 18277 Driveshaft maintenance question by pepper50 Jun 16, 2005 (9:53 pm)
I had asked earlier about whether the driveshaft needed to be dropped and lubed on a 2002 Envoy 2WD at the 30,000 service like my dealer wanted to do. I had also asked that question in a GM trucks group and this is an answer I got, but not sure of its relevance to Envoy.:   I don't know about the Envoy, but late model GM trucks have a problem with spline bind at the yoke. Pulling the shaft and lubing the spline/yoke alleviates the problem(for a while).   I have a feeling he's referring to full-size GM trucks, and not these mid-size SUVs, but I don't know. Anyone ever hear of such applying to Envoys or TBs?? Is there a TSB on it or mention in the service manual? Thanks. Replies to this message: burdawg (Jun 17, 2005 6:04 am)

Replying to: pepper50 (Jun 16, 2005 9:53 pm) Well, maybe. I can see this level of service for something that is exposed to water or dirt often, such going off road often or living in a very wet climate where the universal joint needle bearings or spline shaft could be contaminated. For general purposes though it could be overkill. If you drive on bumpy dirt roads often, you may want to consider it since the spline shaft will get more movement in the transmission tail housing plus will get coated with more dirt/dust, in effect drying it out.

Replying to: tblazed (May 29, 2005 1:27 pm) hi I have similar proble with 03 trailblazer -- the heater when turned on above 2, the heater motor makes a rumbling noise and seems to shake the whole vehicle. Is the motor bad?   thanks Replies to this message: tblazed (Jun 17, 2005 11:56 am)

Replying to: timkite (Jun 17, 2005 9:53 am) Don't know.. that other situation was no power at all to the motor on speeds 1-3 . Probably have to take the blower-motor ass'y out to see what's going on inside. Maybe something fell in through a vent or duct and is rubbing or obstructing the blower.

Replying to: gmfan (Jun 07, 2005 4:12 am) I guess everyone has his or her own experiences. I use nothing but Anco and I love 'em. I've tried Bosch, Trico, and others, but in my view, they don't compare to Anco.
#16842 of 18277 Power Window/ Power lock switch light bulb by malibu99 Jun 17, 2005 (10:57 pm)
Hello everyone   I have a 2002 Trailblazer and the passenger side front door power window/power lock switch light is out. My question is...is this a simple bulb I can replace myself and if so how do I go about it? Does the plastic trim around the switch just pop out? Or is this one of those where the bulb is built in and the whole switch needs replacement? Please help.   Joe Replies to this message: johntr (Jun 23, 2005 3:57 am)

Replying to: gmfan (Jun 10, 2005 11:11 am) My 04 Envoy has manual heating and a/c controls. My a/c has done the same thing. Do you think I can reset it. It first done it on the hottest day so far here on the east coast. In a funeral convoy seemed like it took forever for a/c to kick in.

#16844 of 18277 trailblazer dvd player by johnh123 Jun 19, 2005 (5:59 pm)
Anyone know what kind of media the dvd player in the 03 trailblazer will play? Will it play dvd-r, dvd+r, svcd?   Any help would be appreciated. Replies to this message: wxman4 (Jun 20, 2005 6:06 pm) glubash (Jan 18, 2009 8:59 am) glubash (Jan 23, 2009 5:03 pm)

Replying to: b36 (Jun 18, 2005 11:17 am) What I do is crack the windows to alleviate the interior temperatures while sitting in the sun on a hot day. I crank up the vehicle (my a/c is already turned on since I run it constantly here in the south), and then I press the rear defrost button and and hold down for about five seconds, and then release. The rear defrost button will still be lit up and it seems to help get the compressor going a little quicker. It does not work every time, but it seems to help get it cooling quicker. Once I get moving down the road and I can feel the air cooling, then I turn off the rear defrost button. I guess you could try the front defrost setting for a little and then switch back to a/c cycle...I may give that a try this afternoon. Once mine starts cooling, it cools great, but it should take only thirty seconds to cool like I want it do, not a minute +. One other thing I do is run outside air first when the vehicle has been sitting in the hot sun because if you start out on recirculate mode it will take longer since all it is doing is recirculating hot interior air. After it starts cooling, I switch to recirculate mode if outside is not doing enough.   tblazed has the same issue on his and he says there is no fix yet (he would know) Replies to this message: tblazed (Jun 20, 2005 6:34 am) steveapc (Jul 16, 2005 1:20 pm) wxman4 (Jul 16, 2005 3:53 pm) notfair (Aug 05, 2005 2:09 pm) and 4 more...

I've tried running in outside air mode during the first min and, in my situation anyway, didn't work any better - actually seemed to slow the cooling process - so the results doing that probably has a lot to do with how humid the outside air is. I have found it cools down the hotter less humid interior air faster than the somewhat cooler but much more humid outside air. One thing I do at startup is reach behind and turn on the rear A/C vents on the back of the console to help get the overall interior cooler as soon as possible.
